Device & OS
not provided
Scenario
A user returns to an organization and their previous Microsoft 365 account is restored or recreated using the same email address.
Observed behavior
The user receives a permission error or access-denied message when attempting to open OneDrive or create new Word and Excel files in the web browser.
Before you start

Ensure you have Microsoft 365 global or SharePoint administrator privileges, as resolving account identity mismatches requires access to the Microsoft 365 Admin Center.

Solution 1Recommended

Resolve the Account Identity Mismatch

Fix the backend identity conflict that occurs when an account is recreated with the same User Principal Name (UPN) but a different internal identifier.

When a user leaves and returns, administrators often recreate the account using the same email address. However, SharePoint and OneDrive still recognize the old, deleted identity's unique ID, causing a permission conflict for the new account.

1
Run the SharePoint diagnostic tool

Log into the Microsoft 365 Admin Center, navigate to the Help & Support section, and run the 'Check SharePoint User Access' diagnostic tool for the affected user.

2
Remove the old user profile

Access the SharePoint admin center, locate the user's personal OneDrive site collection, and remove the mismatched account from the Site Collection Administrators list.

3
Grant access to the new identity

Manually add the newly recreated user account back to the Site Collection Administrators list to grant explicit permissions to their OneDrive site.

Resolve the Account Identity Mismatch
Diagnostic Tool Automation: In many cases, running the Microsoft 365 diagnostic tool will automatically detect the PUID (Passport Unique Identifier) mismatch and offer a one-click fix.

Frequently Asked Questions

Why do I get an access denied error on OneDrive after my account was restored?

This happens because the recreated account has a new internal unique identifier (PUID), but OneDrive still associates your files and permissions with the old identifier of your previous account, resulting in a permission mismatch.

Can a standard user fix this OneDrive permission issue?

No, standard users cannot resolve this backend identity mismatch. You must contact your organization's Microsoft 365 administrator to re-sync your account identity or reassign your license.

Will I lose my old OneDrive files when my account is recreated?

Your files are usually preserved if the account is restored within Microsoft's standard retention period (typically 30 days). Once your administrator fixes the identity mismatch, you will regain access to your previous files.
