Send Teams Message

Sends a message to a Microsoft Teams recipient — a direct user, a team channel, or a group chat — using a configured Microsoft 365 service account.

Purpose

Use this task to deliver automated notifications or communications via Microsoft Teams from within a workflow. The message type determines the target: a single user by email, a named channel within a team, or a multi-user group chat. Messages can be sent as plain HTML text or as a structured Adaptive Card for richer formatting. A valid Microsoft 365 linked account must be configured on the task.
