How do I set up custom OAuth credentials for Microsoft (Outlook)?

For a step-by-step guide on creating and configuring your own Microsoft (Outlook) OAuth credentials with Composio, see How to create OAuth credentials for Microsoft (Outlook).

Why does the Outlook new message trigger only return a message ID?

Outlook's webhooks send only the message ID on trigger events. To get the full message (subject, body, headers), call the OUTLOOK_GET_MESSAGE tool with that message ID.

Why doesn't OUTLOOK_SEND_EMAIL return message details?

Microsoft Graph's send endpoint returns an HTTP 202 with no message details. To get the message ID and conversation ID, create a draft first with OUTLOOK_CREATE_DRAFT, then send it with OUTLOOK_SEND_DRAFT. See Microsoft Graph docs.

What's the @odata.context / @odata URL?

The @odata.context URL provides metadata about the response (entity set, service version, and schema info) to help clients interpret the payload structure. It's primarily used for pagination and data parsing — not as a direct URL to the resource itself.
