We have Windows 2008 R2 ADRMS server.
Lately we have experiencing a very strange behaviour. We can protect the documents with RMS. But if we want to reopen the file to modify the list of people there, after adding people and saving the rights some of the people are disappearing from the list.
After some investigation we found that their email address somehow is being changed to X500 address rather then classic SMTP format.
So from the list of 40 users half of them still have their "email@example.com" and others have "/O=Organization...."
Any idea ?
