Protected file decryption

Gayathri-VGM 

If a user has protected a file using Information Rights Management (IRM) in Excel, it is designed to enforce specific access controls and restrictions on the file. These restrictions are often tied to user identities and tenant configurations, which means that even if a user has the file, they may not be able to access its contents if the necessary permissions or identity conditions are not met.

In cases where a user has migrated to a different tenant or there have been changes in account deletion or permissions, it can indeed affect the ability to access IRM-protected files. IRM protection is meant to be highly secure and cannot be easily bypassed, especially if it is functioning as intended.

To address this issue, you would typically need to involve your IT administrators or Microsoft Support, as they would have the expertise to troubleshoot and potentially help recover access to the protected file. Here are some steps you can take:

1. Contact Microsoft Support: If you suspect that the issue is related to tenant changes or account deletion, contacting Microsoft Support would be the best approach. They can provide guidance specific to your situation and may be able to help you recover access to the file.
2. Review Tenant Changes: If the user's migration or account deletion is suspected to be the cause of the issue, work with your IT team to review the changes and their potential impact on file access.
3. Check IRM Configuration: Make sure that the IRM settings and configurations within your tenant are correctly set up. Incorrect or misconfigured IRM settings could lead to access issues.
4. User Identity and Authentication: Ensure that the user's identity and authentication are properly set up in the new tenant and that they have the necessary permissions to access the IRM-protected content.

Please, Remember that IRM is designed to protect sensitive content and prevent unauthorized access, so any attempt to bypass its protection mechanisms would likely be complex and require careful handling by professionals familiar with IRM and encryption technologies.
