The MRU list opens other users' folders. Any time that you open a folder that someone else owns (Inbox, Calendar, Contacts, and so on), Outlook stores that folder in a list so that you can gain access to the folder more quickly the next time that you open the folder. To open another user's folder:
On the File menu, point to Open, and then clickOther User's Folder.
In the Name box, type the name of the person who granted you sharing or delegate access permission, or click Name to select aname from a list.
In the Folder box, click the folder that you want to open.
