This article describes the Outlook Most Recently Used (MRU) list and how to clear it.

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:
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:

1.	On the File menu, point to Open, and then click Other User's Folder.
2.	In the Name box, type the name of the person who granted you sharing or delegate access permission, or click Name to select a name from a list.
3.	In the Folder box, click the folder that you want to open.

The MRU list is saved in the registry. You may want to clear the MRU list (if someone in the list is no longer with your company, for example).

To clear the MRU list, follow these steps.
