Today, we are announcing the deprecation of the classic Exchange admin center (EAC) in Microsoft 365 operated by 21Vianet. The modern EAC is already available in Microsoft 365 operated by 21Vianet and can be accessed at

The classic EAC will be deprecated by September 30, 2023. After this date, admins in this environment will not be able to use the classic EAC. The modern EAC offers an array of new features, including a streamlined interface, enhanced performance, and security.

We recommend admins in this environment transition to the modern EAC as soon as possible.
