HELP! Former IRM setup keeps a complete document library on lock (SharePoint Online)

Iron Contributor

A customer of ours is working in SharePoint Online with a document library.

This library once was protected with Information Rights Management.


The settings were disabled years ago and even the policies are removed later on.


A while back some users discovered that all older files are still protected with IRM and are unable to open any of these older documents. New documents are working normally.


Is there any way on how to unprotect these documents in bulk?

We already started a supportcase without a solution, i have a Partner Manager reaching out within Microsoft but havent had any luck on cracking those documents.


We also tested creating a similar situation on a new sitecollection by enabling IRM on a library. We copied some of these protected files and some new files in it, and disabled IRM. Alle regular files are unprotected but the previously protected files are still locked.


Anyone any suggestions?
