Fix Cannot Restore a Deleted Microsoft 365 User Account Error
Question details
An administrator is unable to restore a Microsoft 365 user account that was deleted two days ago and is receiving a recurring failure message.
- Product
- Microsoft 365
- Device & OS
- not provided
- Scenario
- Attempting to restore a recently deleted Microsoft 365 user account through the standard admin interfaces.
- Observed behavior
- The system fails to recover the account and repeatedly returns the error message: 'We couldn't restore the user. Please try again later.'
Ensure you are signed in with Global Administrator or User Management Administrator credentials, as standard users cannot initiate backend support requests for tenant restoration issues.
Contact Microsoft 365 Support for Backend Investigation
Because the automated restoration process has failed and is returning a generic error, Microsoft backend engineers must investigate your tenant to manually clear the block and restore the user.
When an account deleted within the standard 30-day recovery window fails to restore, it usually indicates a synchronization issue or a backend conflict within the Microsoft 365 tenant data. Standard troubleshooting steps will not resolve this.
You must open a formal service request through the admin center or call Microsoft Business Support directly.
Navigate to the Microsoft 365 admin center (admin.microsoft.com) and log in using your administrator credentials.
Click the 'Help & support' icon located in the bottom right corner of the admin center screen, or access it from the left-hand navigation pane.
Type a brief description of the restoration failure. Bypass the automated bot suggestions by clicking the option to contact support. Provide detailed information including the deleted user's account name, the exact date of deletion, your tenant details, and the verbatim error message you are receiving.
If you cannot submit a ticket online, visit the official Microsoft 365 'Support contact info' page to find the localized business support phone number for your region and call them directly with your tenant ID ready.

Frequently Asked Questions
How long do I have to restore a deleted Microsoft 365 user?
Microsoft 365 retains deleted user accounts and their associated data in a soft-deleted state for exactly 30 days. After this 30-day retention period, the account and all its data are permanently deleted from the backend and cannot be recovered.
Who has the permission to restore deleted users in Microsoft 365?
Only users assigned the Global Administrator or User Management Administrator roles have the necessary permissions to view and restore deleted user accounts within the Microsoft 365 admin center.
What data is recovered when I successfully restore a Microsoft 365 user?
When you successfully restore a user account within the 30-day window, all their associated data—including their Exchange Online mailbox, OneDrive files, Teams data, and access permissions—are fully restored to the state they were in prior to deletion.
