Today, we are announcing the deprecation of the classic Exchange admin center (EAC) in our GCC and GCC-H environments.
The modern EAC is already available in these environments and can be accessed at:
The classic EAC will be deprecated by August 30, 2023. After that date, admins in those environments 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 these environments transition to the modern EAC as soon as possible.
To learn more about the modern EAC, see Exchange admin center in Exchange Online.
