Dear Krisch,
Thanks for your updates and let us know the situation here.
May I know whether the issue happens in each user in the security group in your environment?
If you save the files in another site library with IRM enabled in another site and do a test there, what's the result?
As the latest version number of the Microsoft 365 Apps for enterprise applications is Version 2009 (Build 13231.20418 Click-to-Run), I'd like you to check whether the version number is fully updated. If no and if it is convenient, I suggest you update the version number, restart the computer and then do a test to see the result again.
Best Regards,
Cliff
Hi Cliff,
I have tried all of those but still receive that same error message...
I also tried with a security group that has full permissions, but it doesn't change a thing.
Kind regards
