Videos: Audio Conferencing in Microsoft Teams
The Microsoft Teams admin center is gradually replacing the Skype for Business admin center, and we're migrating Teams settings to it from the Microsoft 365 admin center. If a setting has been migrated, you'll see a notification and then be directed to the setting's location in the Teams admin center. For more information, see Manage Teams during the transition to the Teams admin center.
