For Microsoft Teams meetings that are managed by using a shared mailbox, only a limited number of features are available. The following table lists the details of each feature.
Note
Shared mailboxes aren't intended for direct login. Keep the shared mailbox account in the Disabled state, and avoid resetting its password or signing in by using the shared mailbox user account.
Available feature
Details
Create meetings
The meeting must be created by a delegate by using the shared mailbox calendar.
The meeting must be updated by using the shared mailbox calendar.
The meeting can be updated by the delegate who organizes the meeting, or by other delegates who have Full Access permission to the shared mailbox.
Update meeting options
Meeting options can be updated only by the delegate who organizes the meeting, or by co-organizers who have delegate access to the shared mailbox.
Depending on how the shared mailbox is added to Microsoft Outlook, in some scenarios, you might not be able to access the meeting options for a meeting that's scheduled by using the shared mailbox. In this case, a workaround is to remove the shared mailbox and then add it again by using the File > Add Account option in Outlook.
Note: Meetings created for a mailbox that doesn't have an Audio Conferencing license will lack the Public Switched Telephone Network (PSTN) details in the meeting invitation.
Create custom meeting policies
To create custom meeting policies, the shared mailbox must be assigned a Teams license.
