Hi @alex
The Teams Meeting add-in is still building functionality, so be aware of the following:
- Users can't schedule live events from within Outlook. Go to Teams to schedule live events. For more information, see What are Microsoft Teams live events?
- The Teams Meeting add-in requires an Exchange mailbox for the primary user scheduling the meeting. Ensure that you have at least one Exchange mailbox configured in your Outlook profile and use it to schedule Teams meetings with the add-in. For Exchange requirements, see How Exchange and Teams interact.
- The add-in is for scheduled meetings with specific participants, not for meetings in a channel. Channel meetings must be scheduled from within Teams
