Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi Nikesh, if all the admin cannot access the admin portal, it may be also caused by an UI issue. My suggest is to use PowerShell cmdlet to see if you are able to connect to admin center.
You can run the following cmdlets:
- Connect to Office 365 PowerShell
- $role = Get-MsolRole -RoleName "Company Administrator"
- Get-MsolRoleMember -RoleObjectId $role.ObjectId
You can share the result to us in the private message which I will generate for you later.
Regards,
SD
