- Scenario

- Observed behavior

Submit a Service Request via Microsoft 365 Admin Center
Use this solution to have Microsoft support engineers investigate backend tenant synchronization and account permission issues.
If your permissions are correctly configured but the Exchange Admin Center remains inaccessible, the issue is likely tied to a backend service glitch, a tenant provisioning error, or a temporary service outage.
Because these issues are on Microsoft's servers, a support engineer must manually check your tenant status and reset backend access tokens.
Open your web browser, navigate to admin.microsoft.com, and log in using your administrator credentials.
On the left-hand navigation pane, scroll down and click on 'Support', then select 'Help & support' or 'New service request'.
In the search bar, type 'Cannot open Exchange Admin Center' and review the automated diagnostics. If the issue is not resolved, click 'Contact Support'.
Fill in your contact details, provide a brief description of the issue including the fact that other admin centers are working, and click 'Contact me' to submit the request.

Frequently Asked Questions
Why can I access Microsoft 365 but not the Exchange Admin Center?
This typically occurs if your account is assigned a limited administrative role (like Billing Admin) rather than the Global Admin or Exchange Admin role. It can also happen due to backend synchronization delays after permissions are newly assigned.
How can I check if Exchange Online is experiencing an outage?
Log into the Microsoft 365 admin center, navigate to 'Health' on the left menu, and click 'Service health'. Look for any active incidents or advisories specifically affecting Exchange Online.
Is there a direct link to access the Exchange Admin Center?
Yes. You can bypass the main Microsoft 365 admin portal by typing 'admin.exchange.microsoft.com' directly into your browser's address bar. If you still receive an access denied error, you will need to contact support.
