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.

There are a handful of cases that have reported the same situation. There has been an escalation made with our Engineering team to get this resolved. There has been a fix applied to the server, but it will take around a week to fully deploy. I will follow up with you next Thursday to confirm if you are still seeing the issue, if that is okay.- BogdanofffFeb 05, 2022Brass ContributorI wanted to share I was able to resolve this issue. I had to directly assign permissions to the shared mail box and make sure that automapping was on. - No security Groups.
The kicker is to get IRM to kick off and check permissions. I recently learned in Outlook - Double clicking the email or reading it in pop-out mode can initiate permissions check and allow the user to read the email in the Outlook application. No more redirection via edge, the content can be read from the mail box.
