User with full access to shared mailbox can't open protected email in Outlook
EsaggeseIf a target recipient is a "regular" mailbox, but not specifically configured as a "shared" mailbox, and multiple authenticated users have delegated access to this mailbox, is it expected these authenticated users should be able to open the message/document? Or is it important that the "shared" mailbox be a true shared mailbox? (I just want to be sure before we try to convert to a truly shared mailbox as there are automated processes that also pull content from the mailbox).
Scott Wakeman I'm no longer working on that area but my understanding is that with the updates shipped last year if the user is directly assigned full access permissions to a mailbox, they should be able to view protected content to which the owner of that mailbox has rights. But there are some constraints, for example if rights are granted indirectly through a group that doesn't work. I recommend consulting in the Exchange forums for more details.
