Recover Access to an Excel File Protected with Information Rights Management
Question details
The user needs to regain authorized access to an Excel workbook protected by Information Rights Management after tenant migration, account deletion, or identity changes.
- Product
- Microsoft Excel / Microsoft 365 Information Rights Management
- Device & OS
- not provided
- Scenario
- A previously authorized user can no longer open an IRM-protected Excel workbook because the underlying identity, permissions, or tenant configuration changed.
- Observed behavior
- Excel blocks the workbook from opening, or the user receives a permission or identity error despite having the file.
Before attempting recovery, identify the original Microsoft 365 tenant, the account that applied IRM protection, and any tenant migration or account deletion details. Keep the original Excel file unchanged and do not try to remove protection manually.
Verify permissions and identity with the original tenant administrator
Use this solution first when a formerly authorized user cannot open an IRM-protected workbook after tenant migration or account changes.
IRM restrictions are tied to Microsoft 365 identities and tenant policies. A changed or deleted account can revoke access even if the file is still available.
Sign in to the original tenant's Microsoft 365 admin center with an administrator account, then go to Users > Active users and confirm whether the user account still exists and is licensed.
In the Microsoft Entra admin center or compliance portal, review the user's roles, group memberships, and any sensitivity label or IRM policy that grants rights to the protected workbook.
In the admin center, check Migration logs or service health information to confirm whether the identity was migrated to a new tenant or whether the original tenant was decommissioned.
Ask the original tenant administrator to grant the user appropriate permissions in the protection policy or to re-protect the workbook in the new tenant.
Contact Microsoft Support when the original tenant is decommissioned
Use this solution when the original tenant no longer exists, the protecting account was deleted, or the tenant administrator cannot recover the identity.
Use WPS Office for Standard Excel Workbooks After IRM Recovery
WPS Office cannot bypass Excel Information Rights Management, which is controlled by Microsoft 365 tenant identity and permissions. For standard Excel workbooks and everyday spreadsheets, WPS Office is a free, lightweight Office alternative with strong .xlsx compatibility, a familiar ribbon interface, and simple migration from Microsoft Excel.
- 1. Download WPS Office: Go to the WPS Office download page and click Download WPS Office Free to install the suite on Windows, macOS, Android, or iOS.
- 2. Open a standard Excel workbook: Launch WPS Spreadsheets, click Menu > Open, and select the .xlsx or .xls file that is not IRM-protected.
- 3. Edit and save: Use the familiar ribbon tools to edit the workbook, then click Menu > Save As and choose Excel format to keep compatibility.
Frequently Asked Questions
Can WPS Office open an Excel file protected by Information Rights Management?
WPS Office cannot bypass or remove IRM protection. IRM is enforced by Microsoft 365 identities and tenant policies, so you must open the file in Microsoft Excel with an authorized account or use an official recovery process.
What should I do first if a tenant migration removed my access to an IRM-protected workbook?
First ask the original tenant administrator to check Microsoft 365 admin center > Users > Active users and verify that your account, license, permissions, and migrated identity are correctly configured.
Can IRM protection be removed by editing or converting the Excel file?
No. IRM protection cannot normally be removed by editing or converting the workbook. Attempts to bypass it are not supported and may not be technically possible.
How do I contact Microsoft Support about an IRM access problem?
Go to support.microsoft.com, sign in with your Microsoft account, select Excel or Microsoft 365, and provide the file name, original tenant domain, migration dates, account deletion history, and the exact error message.
What should I preserve before requesting IRM recovery?
Preserve the original Excel file unchanged, and keep records of the original tenant, the account that protected the file, permissions, licenses, and any migration or deletion events.
