Mass deleting posts

[CoachTom]

I've been tasked with cleaning up a team channel that has gotten absolutely massive, with literally thousands of posts. I have been added as an owner of the team, and while I can delete any comments, it would be incredibly inefficient to delete every post and reply one by one.

Is there a way to delete a post *and all replies to that post* at once, as a team owner? I have not yet found a way to do so. It would be even acceptable for me to do a "hard reset" and delete all posts entirely and just start over, with me curating it moving forward.

Not possible via the UI, but you should be able to automate it via the Graph API: https://docs.microsoft.com/en-us/graph/api/group-delete-thread?view=graph-rest-1.0&tabs=http

It looks like deleting conversations (emails) in O365 groups, not sure if it works for Teams, too...

Graph API does not support yet the deletion of Teams messages

Deletion is still manual today.
