Sometime in the past 4-6 weeks Microsoft changed the dialog box for adding and browsing groups from within the Outlook desktop app to the new web version. In conjunction with that all of my dynamic groups now no longer have a join button that would let me add the inbox/calendar into Outlook, instead the button now says "access restricted" presumably because you can't manually add members to a dynamic group. The problem is, this was the only way to add a group inbox/calendar into Outlook. And yes, I am a member of this group. Does anyone know if another way to accomplish this?
