Opening Protected Messages from a Shared Mailbox
I have a user who has full access with auto mapping to a Shared mailbox who cannot open protected messages. I'm not sure if this related to the https://answers.microsoft.com/en-us/outlook_com/forum/...
We have a user who reported this issue as well around the same time that other users reported the inability to open encrypted emails using the authentication option. I'm also wondering if it's related to the encryption advisory MS still has open. The error message was not consistent with the error message other users were receiving but I think the difference is encrypted emails sent to a shared mailbox (delegated access) versus sent directly to a user. We have an open case with Microsoft regarding the encryption issue so we'll run this past them as well. If I learn anything further, will advise.
The timing of this seemed the same as the advisory. I appreciate the help! Thank you for taking the time to read this!
