Controlling settings, permissions, and membership within Teams and channels
Hi,
I understand now that you’ve already deleted the channel post. What you want to remove is the remaining “This message has been deleted” entry. Microsoft’s current instructions for deleting a Teams message do not provide a further option for removing that entry. I couldn’t verify a supported step that would clear it from an individual post while keeping the channel.
If this is affecting how your channel is used, you can request that option through the Microsoft Teams Feedback portal. If you submit feedback, please share the link here so I can follow it and upvote it as well. I can see how those leftover placeholders make it frustrating to keep your channel tidy. Looking forward to your response.
