Microsoft Teams

Status: text + DM attachments are supported; channel/group file sending requires sharePointSiteId + Graph permissions (see Sending files in group chats). Polls are sent via Adaptive Cards. Message actions expose explicit upload-file for file-first sends.

Bundled plugin

Microsoft Teams ships as a bundled plugin in current OpenClaw releases, so no separate install is required in the normal packaged build.

If you are on an older build or a custom install that excludes bundled Teams, install the npm package directly:

openclaw plugins install @openclaw/msteams

Use the bare package to follow the current official release tag. Pin an exact version only when you need a reproducible install.

Local checkout (when running from a git repo):

openclaw plugins install ./path/to/local/msteams-plugin

Details: Plugins

Quick setup

The @microsoft/teams.cli handles bot registration, manifest creation, and credential generation in a single command.

1. Install and log in

npm install -g @microsoft/teams.cli@preview
teams login
teams status   # verify you're logged in and see your tenant info

2. Start a tunnel (Teams can't reach localhost)

Install and authenticate the devtunnel CLI if you haven't already (getting started guide).

# One-time setup (persistent URL across sessions):
devtunnel create my-openclaw-bot --allow-anonymous
devtunnel port create my-openclaw-bot -p 3978 --protocol auto

# Each dev session:
devtunnel host my-openclaw-bot
# Your endpoint: https://<tunnel-id>.devtunnels.ms/api/messages

Alternatives: ngrok http 3978 or tailscale funnel 3978 (but these may change URLs each session).

3. Create the app

teams app create \
  --name "OpenClaw" \
  --endpoint "https://<your-tunnel-url>/api/messages"

This single command:

• Creates an Entra ID (Azure AD) application
• Generates a client secret
• Builds and uploads a Teams app manifest (with icons)
• Registers the bot (Teams-managed by default — no Azure subscription needed)

The output will show CLIENT_ID, CLIENT_SECRET, TENANT_ID, and a Teams App ID — note these for the next steps. It also offers to install the app in Teams directly.

4. Configure OpenClaw using the credentials from the output:

{
  channels: {
    msteams: {
      enabled: true,
      appId: "<CLIENT_ID>",
      appPassword: "<CLIENT_SECRET>",
      tenantId: "<TENANT_ID>",
      webhook: { port: 3978, path: "/api/messages" },
    },
  },
}

Or use environment variables directly: MSTEAMS_APP_ID, MSTEAMS_APP_PASSWORD, MSTEAMS_TENANT_ID.

5. Install the app in Teams

teams app create will prompt you to install the app — select "Install in Teams". If you skipped it, you can get the link later:

teams app get <teamsAppId> --install-link

6. Verify everything works

teams app doctor <teamsAppId>

This runs diagnostics across bot registration, AAD app config, manifest validity, and SSO setup.

For production deployments, consider using federated authentication (certificate or managed identity) instead of client secrets.

Goals

• Talk to OpenClaw via Teams DMs, group chats, or channels.
• Keep routing deterministic: replies always go back to the channel they arrived on.
• Default to safe channel behavior (mentions required unless configured otherwise).

Config writes

By default, Microsoft Teams is allowed to write config updates triggered by /config set|unset (requires commands.config: true).

Disable with:

{
  channels: { msteams: { configWrites: false } },
}

Access control (DMs + groups)

DM access

• Default: channels.msteams.dmPolicy = "pairing". Unknown senders are ignored until approved.
• channels.msteams.allowFrom should use stable AAD object IDs.
• Do not rely on UPN/display-name matching for allowlists — they can change. OpenClaw disables direct name matching by default; opt in explicitly with channels.msteams.dangerouslyAllowNameMatching: true.
• The wizard can resolve names to IDs via Microsoft Graph when credentials allow.

Group access

• Default: channels.msteams.groupPolicy = "allowlist" (blocked unless you add groupAllowFrom). Use channels.defaults.groupPolicy to override the default when unset.
• channels.msteams.groupAllowFrom controls which senders can trigger in group chats/channels (falls back to channels.msteams.allowFrom).
• Set groupPolicy: "open" to allow any member (still mention‑gated by default).
• To allow no channels, set channels.msteams.groupPolicy: "disabled".

Example:

{
  channels: {
    msteams: {
      groupPolicy: "allowlist",
      groupAllowFrom: ["[email protected]"],
    },
  },
}

Teams + channel allowlist

• Scope group/channel replies by listing teams and channels under channels.msteams.teams.
• Keys should use stable Teams conversation IDs from Teams links, not mutable display names.
• When groupPolicy="allowlist" and a teams allowlist is present, only listed teams/channels are accepted (mention‑gated).
• The configure wizard accepts Team/Channel entries and stores them for you.
• On startup, OpenClaw resolves team/channel and user allowlist names to IDs (when Graph permissions allow) and logs the mapping; unresolved team/channel names are kept as typed but ignored for routing by default unless channels.msteams.dangerouslyAllowNameMatching: true is enabled.

Example:

{
  channels: {
    msteams: {
      groupPolicy: "allowlist",
      teams: {
        "My Team": {
          channels: {
            General: { requireMention: true },
          },
        },
      },
    },
  },
}

If you can't use the Teams CLI, you can set up the bot manually through the Azure Portal.

How it works

1. Ensure the Microsoft Teams plugin is available (bundled in current releases).
2. Create an Azure Bot (App ID + secret + tenant ID).
3. Build a Teams app package that references the bot and includes the RSC permissions below.
4. Upload/install the Teams app into a team (or personal scope for DMs).
5. Configure msteams in ~/.openclaw/openclaw.json (or env vars) and start the gateway.
6. The gateway listens for Bot Framework webhook traffic on /api/messages by default.

Step 1: Create Azure Bot

1. Go to Create Azure Bot

2. Fill in the Basics tab:

   Field	Value
   Bot handle	Your bot name, e.g., openclaw-msteams (must be unique)
   Subscription	Select your Azure subscription
   Resource group	Create new or use existing
   Pricing tier	Free for dev/testing
   Type of App	Single Tenant (recommended - see note below)
   Creation type	Create new Microsoft App ID

3. Click Review + create → Create (wait ~1-2 minutes)

Step 2: Get Credentials

1. Go to your Azure Bot resource → Configuration
2. Copy Microsoft App ID → this is your appId
3. Click Manage Password → go to the App Registration
4. Under Certificates & secrets → New client secret → copy the Value → this is your appPassword
5. Go to Overview → copy Directory (tenant) ID → this is your tenantId

Step 3: Configure Messaging Endpoint

1. In Azure Bot → Configuration
2. Set Messaging endpoint to your webhook URL:
   • Production: https://your-domain.com/api/messages
   • Local dev: Use a tunnel (see Local Development below)

Step 4: Enable Teams Channel

1. In Azure Bot → Channels
2. Click Microsoft Teams → Configure → Save
3. Accept the Terms of Service

Step 5: Build Teams App Manifest

• Include a bot entry with botId = <App ID>.
• Scopes: personal, team, groupChat.
• supportsFiles: true (required for personal scope file handling).
• Add RSC permissions (see RSC Permissions).
• Create icons: outline.png (32x32) and color.png (192x192).
• Zip all three files together: manifest.json, outline.png, color.png.

Step 6: Configure OpenClaw

{
  channels: {
    msteams: {
      enabled: true,
      appId: "<APP_ID>",
      appPassword: "<APP_PASSWORD>",
      tenantId: "<TENANT_ID>",
      webhook: { port: 3978, path: "/api/messages" },
    },
  },
}

Environment variables: MSTEAMS_APP_ID, MSTEAMS_APP_PASSWORD, MSTEAMS_TENANT_ID.

Step 7: Run the Gateway

The Teams channel starts automatically when the plugin is available and msteams config exists with credentials.

Federated authentication (certificate plus managed identity)

Added in 2026.4.11

For production deployments, OpenClaw supports federated authentication as a more secure alternative to client secrets. Two methods are available:

Option A: Certificate-based authentication

Use a PEM certificate registered with your Entra ID app registration.

Setup:

1. Generate or obtain a certificate (PEM format with private key).
2. In Entra ID → App Registration → Certificates & secrets → Certificates → Upload the public certificate.

Config:

{
  channels: {
    msteams: {
      enabled: true,
      appId: "<APP_ID>",
      tenantId: "<TENANT_ID>",
      authType: "federated",
      certificatePath: "/path/to/cert.pem",
      webhook: { port: 3978, path: "/api/messages" },
    },
  },
}

Env vars:

• MSTEAMS_AUTH_TYPE=federated
• MSTEAMS_CERTIFICATE_PATH=/path/to/cert.pem

Option B: Azure Managed Identity

Use Azure Managed Identity for passwordless authentication. This is ideal for deployments on Azure infrastructure (AKS, App Service, Azure VMs) where a managed identity is available.

How it works:

1. The bot pod/VM has a managed identity (system-assigned or user-assigned).
2. A federated identity credential links the managed identity to the Entra ID app registration.
3. At runtime, OpenClaw uses @azure/identity to acquire tokens from the Azure IMDS endpoint (169.254.169.254).
4. The token is passed to the Teams SDK for bot authentication.

Prerequisites:

• Azure infrastructure with managed identity enabled (AKS workload identity, App Service, VM)
• Federated identity credential created on the Entra ID app registration
• Network access to IMDS (169.254.169.254:80) from the pod/VM

Config (system-assigned managed identity):

{
  channels: {
    msteams: {
      enabled: true,
      appId: "<APP_ID>",
      tenantId: "<TENANT_ID>",
      authType: "federated",
      useManagedIdentity: true,
      webhook: { port: 3978, path: "/api/messages" },
    },
  },
}

Config (user-assigned managed identity):

{
  channels: {
    msteams: {
      enabled: true,
      appId: "<APP_ID>",
      tenantId: "<TENANT_ID>",
      authType: "federated",
      useManagedIdentity: true,
      managedIdentityClientId: "<MI_CLIENT_ID>",
      webhook: { port: 3978, path: "/api/messages" },
    },
  },
}

Env vars:

• MSTEAMS_AUTH_TYPE=federated
• MSTEAMS_USE_MANAGED_IDENTITY=true
• MSTEAMS_MANAGED_IDENTITY_CLIENT_ID=<client-id> (only for user-assigned)

AKS Workload Identity Setup

For AKS deployments using workload identity:

1. Enable workload identity on your AKS cluster.

2. Create a federated identity credential on the Entra ID app registration:

   bashCopy

   az ad app federated-credential create --id <APP_OBJECT_ID> --parameters '{
     "name": "my-bot-workload-identity",
     "issuer": "<AKS_OIDC_ISSUER_URL>",
     "subject": "system:serviceaccount:<NAMESPACE>:<SERVICE_ACCOUNT>",
     "audiences": ["api://AzureADTokenExchange"]
   }'
   

3. Annotate the Kubernetes service account with the app client ID:

   yamlCopy

   apiVersion: v1
   kind: ServiceAccount
   metadata:
     name: my-bot-sa
     annotations:
       azure.workload.identity/client-id: "<APP_CLIENT_ID>"
   

4. Label the pod for workload identity injection:

   yamlCopy

   metadata:
     labels:
       azure.workload.identity/use: "true"
   

5. Ensure network access to IMDS (169.254.169.254) — if using NetworkPolicy, add an egress rule allowing traffic to 169.254.169.254/32 on port 80.

Auth type comparison

Default behavior: When authType is not set, OpenClaw defaults to client secret authentication. Existing configurations continue to work without changes.

Local development (tunneling)

Teams can't reach localhost. Use a persistent dev tunnel so your URL stays the same across sessions:

# One-time setup:
devtunnel create my-openclaw-bot --allow-anonymous
devtunnel port create my-openclaw-bot -p 3978 --protocol auto

# Each dev session:
devtunnel host my-openclaw-bot

Alternatives: ngrok http 3978 or tailscale funnel 3978 (URLs may change each session).

If your tunnel URL changes, update the endpoint:

teams app update <teamsAppId> --endpoint "https://<new-url>/api/messages"

Testing the Bot

Run diagnostics:

teams app doctor <teamsAppId>

Checks bot registration, AAD app, manifest, and SSO configuration in one pass.

Send a test message:

1. Install the Teams app (use the install link from teams app get <id> --install-link)
2. Find the bot in Teams and send a DM
3. Check gateway logs for incoming activity

Environment variables

All config keys can be set via environment variables instead:

• MSTEAMS_APP_ID
• MSTEAMS_APP_PASSWORD
• MSTEAMS_TENANT_ID
• MSTEAMS_AUTH_TYPE (optional: "secret" or "federated")
• MSTEAMS_CERTIFICATE_PATH (federated + certificate)
• MSTEAMS_CERTIFICATE_THUMBPRINT (optional, not required for auth)
• MSTEAMS_USE_MANAGED_IDENTITY (federated + managed identity)
• MSTEAMS_MANAGED_IDENTITY_CLIENT_ID (user-assigned MI only)

Member info action

OpenClaw exposes a Graph-backed member-info action for Microsoft Teams so agents and automations can resolve channel member details (display name, email, role) directly from Microsoft Graph.

Requirements:

• Member.Read.Group RSC permission (already in the recommended manifest)
• For cross-team lookups: User.Read.All Graph Application permission with admin consent

The action is gated by channels.msteams.actions.memberInfo (default: enabled when Graph credentials are available).

History context

• channels.msteams.historyLimit controls how many recent channel/group messages are wrapped into the prompt.
• Falls back to messages.groupChat.historyLimit. Set 0 to disable (default 50).
• Fetched thread history is filtered by sender allowlists (allowFrom / groupAllowFrom), so thread context seeding only includes messages from allowed senders.
• Quoted attachment context (ReplyTo* derived from Teams reply HTML) is currently passed as received.
• In other words, allowlists gate who can trigger the agent; only specific supplemental context paths are filtered today.
• DM history can be limited with channels.msteams.dmHistoryLimit (user turns). Per-user overrides: channels.msteams.dms["<user_id>"].historyLimit.

Current Teams RSC permissions (manifest)

These are the existing resourceSpecific permissions in our Teams app manifest. They only apply inside the team/chat where the app is installed.

For channels (team scope):

• ChannelMessage.Read.Group (Application) - receive all channel messages without @mention
• ChannelMessage.Send.Group (Application)
• Member.Read.Group (Application)
• Owner.Read.Group (Application)
• ChannelSettings.Read.Group (Application)
• TeamMember.Read.Group (Application)
• TeamSettings.Read.Group (Application)

For group chats:

• ChatMessage.Read.Chat (Application) - receive all group chat messages without @mention

To add RSC permissions via the Teams CLI:

teams app rsc add <teamsAppId> ChannelMessage.Read.Group --type Application

      ],
    },
  },
}

Manifest caveats (must-have fields)

• bots[].botId must match the Azure Bot App ID.
• webApplicationInfo.id must match the Azure Bot App ID.
• bots[].scopes must include the surfaces you plan to use (personal, team, groupChat).
• bots[].supportsFiles: true is required for file handling in personal scope.
• authorization.permissions.resourceSpecific must include channel read/send if you want channel traffic.

Updating an existing app

To update an already-installed Teams app (e.g., to add RSC permissions):

# Download, edit, and re-upload the manifest
teams app manifest download <teamsAppId> manifest.json
# Edit manifest.json locally...
teams app manifest upload manifest.json <teamsAppId>
# Version is auto-bumped if content changed

After updating, reinstall the app in each team for new permissions to take effect, and fully quit and relaunch Teams (not just close the window) to clear cached app metadata.

1. Update your manifest.json with the new settings
2. Increment the version field (e.g., 1.0.0 → 1.1.0)
3. Re-zip the manifest with icons (manifest.json, outline.png, color.png)
4. Upload the new zip:
   • Teams Admin Center: Teams apps → Manage apps → find your app → Upload new version
   • Sideload: In Teams → Apps → Manage your apps → Upload a custom app

Capabilities: RSC only vs Graph

With Teams RSC only (app installed, no Graph API permissions)

Works:

• Read channel message text content.
• Send channel message text content.
• Receive personal (DM) file attachments.

Does NOT work:

• Channel/group image or file contents (payload only includes HTML stub).
• Downloading attachments stored in SharePoint/OneDrive.
• Reading message history (beyond the live webhook event).

With Teams RSC + Microsoft Graph Application permissions

Adds:

• Downloading hosted contents (images pasted into messages).
• Downloading file attachments stored in SharePoint/OneDrive.
• Reading channel/chat message history via Graph.

RSC vs Graph API

Bottom line: RSC is for real-time listening; Graph API is for historical access. For catching up on missed messages while offline, you need Graph API with ChannelMessage.Read.All (requires admin consent).

Graph-enabled media + history (required for channels)

If you need images/files in channels or want to fetch message history, you must enable Microsoft Graph permissions and grant admin consent.

1. In Entra ID (Azure AD) App Registration, add Microsoft Graph Application permissions:
   • ChannelMessage.Read.All (channel attachments + history)
   • Chat.Read.All or ChatMessage.Read.All (group chats)
2. Grant admin consent for the tenant.
3. Bump the Teams app manifest version, re-upload, and reinstall the app in Teams.
4. Fully quit and relaunch Teams to clear cached app metadata.

Additional permission for user mentions: User @mentions work out of the box for users in the conversation. However, if you want to dynamically search and mention users who are not in the current conversation, add User.Read.All (Application) permission and grant admin consent.

Known limitations

Webhook timeouts

Teams delivers messages via HTTP webhook. If processing takes too long (e.g., slow LLM responses), you may see:

• Gateway timeouts
• Teams retrying the message (causing duplicates)
• Dropped replies

OpenClaw handles this by returning quickly and sending replies proactively, but very slow responses may still cause issues.

Formatting

Teams markdown is more limited than Slack or Discord:

• Basic formatting works: bold, italic, code, links
• Complex markdown (tables, nested lists) may not render correctly
• Adaptive Cards are supported for polls and semantic presentation sends (see below)

Configuration

Key settings (see /gateway/configuration for shared channel patterns):

• channels.msteams.enabled: enable/disable the channel.
• channels.msteams.appId, channels.msteams.appPassword, channels.msteams.tenantId: bot credentials.
• channels.msteams.webhook.port (default 3978)
• channels.msteams.webhook.path (default /api/messages)
• channels.msteams.dmPolicy: pairing | allowlist | open | disabled (default: pairing)
• channels.msteams.allowFrom: DM allowlist (AAD object IDs recommended). The wizard resolves names to IDs during setup when Graph access is available.
• channels.msteams.dangerouslyAllowNameMatching: break-glass toggle to re-enable mutable UPN/display-name matching and direct team/channel name routing.
• channels.msteams.textChunkLimit: outbound text chunk size.
• channels.msteams.chunkMode: length (default) or newline to split on blank lines (paragraph boundaries) before length chunking.
• channels.msteams.mediaAllowHosts: allowlist for inbound attachment hosts (defaults to Microsoft/Teams domains).
• channels.msteams.mediaAuthAllowHosts: allowlist for attaching Authorization headers on media retries (defaults to Graph + Bot Framework hosts).
• channels.msteams.requireMention: require @mention in channels/groups (default true).
• channels.msteams.replyStyle: thread | top-level (see Reply Style).
• channels.msteams.teams.<teamId>.replyStyle: per-team override.
• channels.msteams.teams.<teamId>.requireMention: per-team override.
• channels.msteams.teams.<teamId>.tools: default per-team tool policy overrides (allow/deny/alsoAllow) used when a channel override is missing.
• channels.msteams.teams.<teamId>.toolsBySender: default per-team per-sender tool policy overrides ("*" wildcard supported).
• channels.msteams.teams.<teamId>.channels.<conversationId>.replyStyle: per-channel override.
• channels.msteams.teams.<teamId>.channels.<conversationId>.requireMention: per-channel override.
• channels.msteams.teams.<teamId>.channels.<conversationId>.tools: per-channel tool policy overrides (allow/deny/alsoAllow).
• channels.msteams.teams.<teamId>.channels.<conversationId>.toolsBySender: per-channel per-sender tool policy overrides ("*" wildcard supported).
• toolsBySender keys should use explicit prefixes: id:, e164:, username:, name: (legacy unprefixed keys still map to id: only).
• channels.msteams.actions.memberInfo: enable or disable the Graph-backed member info action (default: enabled when Graph credentials are available).
• channels.msteams.authType: authentication type — "secret" (default) or "federated".
• channels.msteams.certificatePath: path to PEM certificate file (federated + certificate auth).
• channels.msteams.certificateThumbprint: certificate thumbprint (optional, not required for auth).
• channels.msteams.useManagedIdentity: enable managed identity auth (federated mode).
• channels.msteams.managedIdentityClientId: client ID for user-assigned managed identity.
• channels.msteams.sharePointSiteId: SharePoint site ID for file uploads in group chats/channels (see Sending files in group chats).

Routing & Sessions

• Session keys follow the standard agent format (see /concepts/session):
  • Direct messages share the main session (agent:<agentId>:<mainKey>).
  • Channel/group messages use conversation id:
    • agent:<agentId>:msteams:channel:<conversationId>
    • agent:<agentId>:msteams:group:<conversationId>

Reply style: threads vs posts

Teams recently introduced two channel UI styles over the same underlying data model:

The problem: The Teams API does not expose which UI style a channel uses. If you use the wrong replyStyle:

• thread in a Threads-style channel → replies appear nested awkwardly
• top-level in a Posts-style channel → replies appear as separate top-level posts instead of in-thread

Solution: Configure replyStyle per-channel based on how the channel is set up:

{
  channels: {
    msteams: {
      replyStyle: "thread",
      teams: {
        "19:[email protected]": {
          channels: {
            "19:[email protected]": {
              replyStyle: "top-level",
            },
          },
        },
      },
    },
  },
}

Attachments & Images

Current limitations:

• DMs: Images and file attachments work via Teams bot file APIs.
• Channels/groups: Attachments live in M365 storage (SharePoint/OneDrive). The webhook payload only includes an HTML stub, not the actual file bytes. Graph API permissions are required to download channel attachments.
• For explicit file-first sends, use action=upload-file with media / filePath / path; optional message becomes the accompanying text/comment, and filename overrides the uploaded name.

Without Graph permissions, channel messages with images will be received as text-only (the image content is not accessible to the bot). By default, OpenClaw only downloads media from Microsoft/Teams hostnames. Override with channels.msteams.mediaAllowHosts (use ["*"] to allow any host). Authorization headers are only attached for hosts in channels.msteams.mediaAuthAllowHosts (defaults to Graph + Bot Framework hosts). Keep this list strict (avoid multi-tenant suffixes).

Sending files in group chats

Bots can send files in DMs using the FileConsentCard flow (built-in). However, sending files in group chats/channels requires additional setup:

Why group chats need SharePoint

Bots don't have a personal OneDrive drive (the /me/drive Graph API endpoint doesn't work for application identities). To send files in group chats/channels, the bot uploads to a SharePoint site and creates a sharing link.

Setup

1. Add Graph API permissions in Entra ID (Azure AD) → App Registration:

   • Sites.ReadWrite.All (Application) - upload files to SharePoint
   • Chat.Read.All (Application) - optional, enables per-user sharing links

2. Grant admin consent for the tenant.

3. Get your SharePoint site ID:

   bashCopy

   # Via Graph Explorer or curl with a valid token:
   curl -H "Authorization: Bearer $TOKEN" \
     "https://graph.microsoft.com/v1.0/sites/{hostname}:/{site-path}"
   
   # Example: for a site at "contoso.sharepoint.com/sites/BotFiles"
   curl -H "Authorization: Bearer $TOKEN" \
     "https://graph.microsoft.com/v1.0/sites/contoso.sharepoint.com:/sites/BotFiles"
   
   # Response includes: "id": "contoso.sharepoint.com,guid1,guid2"
   

4. Configure OpenClaw:

   json5Copy

   {
     channels: {
       msteams: {
         // ... other config ...
         sharePointSiteId: "contoso.sharepoint.com,guid1,guid2",
       },
     },
   }
   

Sharing behavior

Per-user sharing is more secure as only the chat participants can access the file. If Chat.Read.All permission is missing, the bot falls back to organization-wide sharing.

Fallback behavior

Files stored location

Uploaded files are stored in a /OpenClawShared/ folder in the configured SharePoint site's default document library.

Polls (Adaptive Cards)

OpenClaw sends Teams polls as Adaptive Cards (there is no native Teams poll API).

• CLI: openclaw message poll --channel msteams --target conversation:<id> ...
• Votes are recorded by the gateway in ~/.openclaw/msteams-polls.json.
• The gateway must stay online to record votes.

Presentation cards

Send semantic presentation payloads to Teams users or conversations using the message tool or CLI. OpenClaw renders them as Teams Adaptive Cards from the generic presentation contract.

The presentation parameter accepts semantic blocks. When presentation is provided, the message text is optional.

Agent tool:

{
  action: "send",
  channel: "msteams",
  target: "user:<id>",
  presentation: {
    title: "Hello",
    blocks: [{ type: "text", text: "Hello!" }],
  },
}

CLI:

openclaw message send --channel msteams \
  --target "conversation:19:[email protected]" \
  --presentation '{"title":"Hello","blocks":[{"type":"text","text":"Hello!"}]}'

For target format details, see Target formats below.

Target formats

MSTeams targets use prefixes to distinguish between users and conversations:

CLI examples:

# Send to a user by ID
openclaw message send --channel msteams --target "user:40a1a0ed-..." --message "Hello"

# Send to a user by display name (triggers Graph API lookup)
openclaw message send --channel msteams --target "user:John Smith" --message "Hello"

# Send to a group chat or channel
openclaw message send --channel msteams --target "conversation:19:[email protected]" --message "Hello"

# Send a presentation card to a conversation
openclaw message send --channel msteams --target "conversation:19:[email protected]" \
  --presentation '{"title":"Hello","blocks":[{"type":"text","text":"Hello"}]}'

Agent tool examples:

{
  action: "send",
  channel: "msteams",
  target: "user:John Smith",
  message: "Hello!",
}

{
  action: "send",
  channel: "msteams",
  target: "conversation:19:[email protected]",
  presentation: {
    title: "Hello",
    blocks: [{ type: "text", text: "Hello" }],
  },
}

Proactive messaging

• Proactive messages are only possible after a user has interacted, because we store conversation references at that point.
• See /gateway/configuration for dmPolicy and allowlist gating.

Team and Channel IDs (Common Gotcha)

The groupId query parameter in Teams URLs is NOT the team ID used for configuration. Extract IDs from the URL path instead:

Team URL:

https://teams.microsoft.com/l/team/19%3ABk4j...%40thread.tacv2/conversations?groupId=...
                                    └────────────────────────────┘
                                    Team conversation ID (URL-decode this)

Channel URL:

https://teams.microsoft.com/l/channel/19%3A15bc...%40thread.tacv2/ChannelName?groupId=...
                                      └─────────────────────────┘
                                      Channel ID (URL-decode this)

For config:

• Team key = path segment after /team/ (URL-decoded, e.g., 19:[email protected]; older tenants may show @thread.skype, which is also valid)
• Channel key = path segment after /channel/ (URL-decoded)
• Ignore the groupId query parameter for OpenClaw routing. It is the Microsoft Entra group ID, not the Bot Framework conversation ID used in incoming Teams activities.

Private channels

Bots have limited support in private channels:

Workarounds if private channels don't work:

1. Use standard channels for bot interactions
2. Use DMs - users can always message the bot directly
3. Use Graph API for historical access (requires ChannelMessage.Read.All)

Troubleshooting

Common issues

• Images not showing in channels: Graph permissions or admin consent missing. Reinstall the Teams app and fully quit/reopen Teams.
• No responses in channel: mentions are required by default; set channels.msteams.requireMention=false or configure per team/channel.
• Version mismatch (Teams still shows old manifest): remove + re-add the app and fully quit Teams to refresh.
• 401 Unauthorized from webhook: Expected when testing manually without Azure JWT - means endpoint is reachable but auth failed. Use Azure Web Chat to test properly.

Manifest upload errors

• "Icon file cannot be empty": The manifest references icon files that are 0 bytes. Create valid PNG icons (32x32 for outline.png, 192x192 for color.png).
• "webApplicationInfo.Id already in use": The app is still installed in another team/chat. Find and uninstall it first, or wait 5-10 minutes for propagation.
• "Something went wrong" on upload: Upload via https://admin.teams.microsoft.com instead, open browser DevTools (F12) → Network tab, and check the response body for the actual error.
• Sideload failing: Try "Upload an app to your org's app catalog" instead of "Upload a custom app" - this often bypasses sideload restrictions.

RSC permissions not working

1. Verify webApplicationInfo.id matches your bot's App ID exactly
2. Re-upload the app and reinstall in the team/chat
3. Check if your org admin has blocked RSC permissions
4. Confirm you're using the right scope: ChannelMessage.Read.Group for teams, ChatMessage.Read.Chat for group chats
