How to Fix Exchange Admin Center Recipients Access Errors After Migration
Product
Microsoft Exchange / Microsoft 365
Device & OS
not provided
Scenario
Navigating to the Recipients tab in the Classic Exchange admin center following an account migration.
Observed behavior
A request error prevents access for one specific administrator, while other administrators can access the page normally. The issue persists across different web browsers and computers.
Before you start

Ensure that you have access to another global administrator account in your Microsoft 365 organization, as you will need it to modify the affected account's administrative roles.

Solution 1Recommended

Disable and Re-enable the Administrator Role

Resetting the administrator role helps resolve access errors caused by a corrupted or incorrectly applied permission during the migration process.

During a migration to Microsoft 365, role assignments can occasionally become unsynchronized. Completely removing and reassigning the role forces the system to refresh the administrator's permissions.

1
Log in with a different Global Admin

Sign in to the Microsoft 365 admin center using a secondary global administrator account that is not experiencing the error.

2
Locate the affected user

Navigate to 'Users', click on 'Active users', and search for the administrator account that is unable to access the Recipients section.

3
Remove administrator roles

Click on the user's name to open the properties panel, go to the 'Roles' section, unassign all Exchange and Global administrator roles, and save your changes.

4
Reassign the roles

Wait approximately 5 to 10 minutes for the changes to propagate, then return to the user's properties and reassign the required Exchange and Microsoft 365 administrator roles.

5
Verify access

Log out, sign back in with the originally affected administrator account, and open the Classic Exchange admin center to confirm the Recipients page loads properly.

Disable and Re-enable the Administrator Role
Propagation Time: Allow sufficient time for Microsoft 365 backend systems to synchronize the role changes before testing access again.

Frequently Asked Questions

Why does the Classic Exchange admin center show a request error for only one administrator?

This typically occurs when a specific administrator's role gets corrupted or is incorrectly applied during the account migration to Microsoft 365, creating a mismatch in backend permissions.

Does clearing my browser cache fix the Exchange admin center request error?

While clearing the cache or switching browsers can resolve generic loading issues, this specific migration-related request error usually requires resetting the administrator roles in the Microsoft 365 admin center.

What should I do if resetting my admin role removes my access to the Microsoft 365 admin center?

If you lose access after resetting your role, you must ask another global administrator in your organization to log in, review your account, and explicitly re-grant the necessary administrative privileges.
