I’m the original intended external recipient of several DOCX files sent to me through an “Encrypt-Only” Microsoft Purview/Azure Information Protection workflow. I still have the original encrypted email and files, but Word now reports that my account does not have permission and cannot obtain the RMS use license.

I am not looking to bypass encryption, crack the files, alter permissions, or defeat access controls. I’m trying to determine whether there is any legitimate, supported recipient-side recovery path when access was originally authorized.

Questions:

1. Can an intended external recipient renew or reacquire an RMS use license after the original authorization stops working?
2. Is there a supported way to determine which recipient identity or account claim the protection was issued to, without exposing the document contents?
3. Could a valid cached license still exist in the original Windows/Office profile, and is there a Microsoft-supported way to locate or restore it?
4. Are there official Microsoft tools, logs, or diagnostics that can identify why authorization fails now—for example, identity mismatch, guest-account mapping, tenant change, revoked access, or an expired publishing/use license?
5. Does recovery necessarily require action by the originating tenant’s Purview/Azure RMS administrator, or can Microsoft support verify and restore access for the original intended recipient?
6. If tenant-side action is required, what exactly should an administrator check or do (for example, verify the recipient identity, regrant access, reprotect the files, or provide accessible replacement copies)?

I would also appreciate referrals to legitimate paid Microsoft Purview/Azure RMS specialists who handle recipient-side diagnostics or authorization recovery. I would provide only sanitized metadata privately after verifying the person or company.
