Post to SharePoint
Allow Owners (or Members if Owners allowed) to post a conversation thread from Teams to the corresponding SharePoint site as a new News item. The thread would remain active and could be liked and replied to from the SharePoint site which would in turn update the thread in Teams.
This would be good for important conversations that happen when some of the group members may be out, such as while taking time off for vacation.
This would be really great, because the conversations are 'gone' after a while and we use Teams to share news & updates with everyone. It could be implemented as an extension to "Post in multiple channels".
I would have done this via Power Automate but unfortunately there is no action for posting news via the SharePoint connector.
