Why Teams Can’t Schedule Meetings with (Some) Teams

You can use Microsoft 365 Groups and distribution lists to schedule meetings in the Teams calendar app, but sometimes you can’t schedule meetings with Teams. That sounds odd, but it’s because of the way that Teams selects groups from the Exchange Online GAL to show to users in the “picker” control to select meeting attendees. You can make changes to have Teams show up in the GAL, but that might not be enough if you want everyone in the team to receive meeting invitations.
