I agree it probably should be a Microsoft option> I know there's the old ZoomIt tools (Sysinternals - a Microsoft toolkit) but it's pretty clunky. I'm hearing a lot of this concern that ZOOM can do it but TEAMS can't.
I think there's a Uservoice but doesn't have a lot of traction. Hopefully it'll be something they add in time as they've been targeting a lot of the Zoom features to try to keep users from migrating to Zoom instead.
