Teams meeting recordings are now accumulating as MP4 files in OneDrive for Business and SharePoint Online. If you have Office 365 E5 licenses, you can use an auto-label policy to remove recordings after a set period. If you don’t have those licenses and need to remove recordings, you’ll have to come up with another plan, maybe after tracking the creation of recordings through the Office 365 audit log.
It seems like the original plan outlined at Ignite changed... perhaps because auto-labeling needs Office 365 E5 and not every tenant has these licenses.
