We've set the default org-wide team and its General channel to read-only (only owners can post and reply).
However, this one user (not the team owner) clicked "Schedule a Meeting" while being in that channel, and, surprisingly, the info about that meeting was posted to the read-only channel. Now we can't get rid of it.
So, can anyone suggest a way to do the following:
1) Remove the all info about the meeting from the channel. We were able to cancel the meeting and remove the meeting conversation, but there's a "The meeting **** is cancelled" auto-reply left under the deleted post, and no button to delete it.
2) Prevent users from scheduling meetings in this Read-only channel. I mean, it's an org-wide channel, the invite is sent to hundreds of people. How do you prevent that?
