Teams Message action

Posts a message to a Microsoft Teams channel through the connection's bot. In the action picker it is Teams Message, under Notification Actions.

Fields

Field	Required	Description
Connection	Yes	The Microsoft Teams connection to post through.
Team	Yes	The team to post to, chosen from a picker. Limited to the connection's allowed teams when it curates a subset.
Channel	Yes	The channel within the selected team, chosen from a picker that fills itself once a team is picked. Standard channels only.
Message	No	The message, as rich text. Accepts variables, and is delivered as an Adaptive Card.
Test Recipient Override	No	On the Advanced tab. During a dry run, this step posts to a test team and channel instead of the real destination.

Picking the recipient

Recipient selection is picker-only: pick a team, then a channel within it. You choose display names, never raw ids, and both lists come from the connection. When an administrator has curated a subset of allowed teams on the connection, the team list is that subset.

The pickers stay empty, with a note saying so, until an administrator has granted the connection's Microsoft Graph consent. Until then the action cannot be completed.

Composing the message

The Message field is a rich-text editor offering only the formatting an Adaptive Card can render: bold, italic, links, and bulleted and numbered lists. Underline, strikethrough, superscript, subscript, headings, tables, and inline code are absent because Teams shows their markup as literal characters rather than as formatting.

Links come from the Elements dropdown rather than a toolbar button, and take an external URL only. A link to CMS content would not resolve for whoever reads the message in Teams.

Content pasted from another editor keeps its text and loses only the styling Teams cannot show.

Output

Field	Description
channel	The channel id the message was posted to.
conversationId	The conversation the message was posted into.
activityId	The id of the created message.
