Answer 1

Hi Ackerman, Warren

Thank you for reaching out to Microsoft Q&A

I understand how frustrating it can be when a longstanding aspect of the platform after a year. However, for clarity, this is a user-to-user support forum. Moderators, contributors, and external Microsoft employees participating here do not have access to backend systems or the ability to intervene directly in Microsoft product features.

Given this, I may not you the definitive solution in this situation, but you can try the workarounds below:

Option 1: Delete via Power Automate (Recommended)

you can try to create a flow that deletes its own messages using the Microsoft Teams connector:

Trigger: Manual or scheduled

Action: "Delete a message" (Teams connector)

  - Team: [Your Team]

  - Channel: [Your Channel]  

  - Message ID: [From your flow's posted message output]

Note: Store the messageId from your original "Post message" action and use it later to delete.

Option 2: Use Graph API (Admin/Developer)

DELETE https://graph.microsoft.com/v1.0/teams/{team-id}/channels/{channel-id}/messages/{message-id}

Permissions required: ChannelMessage.Delete (delegated) or Teamwork.Migrate.All (application)

You can try the above workaround method, kindly let me know in the comments for further support.

Answer 2

The inability to delete Adaptive Cards posted by workflows in Microsoft Teams is indeed a known limitation. Currently, workflows support Adaptive Cards but do not provide a method for deleting them once posted. This limitation has been acknowledged, and while it is a significant issue for users, there has been no official workaround provided as of now. Users experiencing this issue may need to monitor updates from Microsoft for any future changes or improvements regarding this functionality.
