If I have a users mailbox with various folders in them, and that user wants to share those folders with certain other users. How do I open those folders from someone elses outlook? When you go to open, other users folder, the only folders listed are the general default folders. The folders I want to share are not in the inbox, they are in separate folders in the mailbox. Any tips on how to accomplish this. Users just want to share certain folders in their mailbox with other users, but we can't figure out how to open those folders on another users PC in outlook.
