Hybrid customers with online and on-premises configurations will be required to upgrade online users from Skype for Business Online to Microsoft Teams by the July 31, 2021 retirement date. Microsoft will provide assisted upgrades to help upgrade remaining Skype for Business Online users to Teams Only mode after the retirement date.
Organizations with a hybrid configuration can continue to use Skype for Business and Teams side-by-side until they're ready to move to Teams Only mode. After the Skype for Business Online retirement date, when a Skype for Business Server user is moved to the cloud, that user will be in Teams Only mode.
After the assisted upgrade is complete, all online users will be in Teams Only mode. Users in Teams Only mode receive incoming chats and calls, and schedule meetings, in Teams. Users in Teams Only mode will not be able to initiate chats or calls or schedule meetings in Skype for Business Online. Teams Only users will still be able to join Skype for Business meetings scheduled by users still using Skype for Business Server.
