Clear the Most Recently Used lists

For certain actions, Outlook holds a list of most recently used items (MRU lists) so you have quicker access to them. In some cases you might want to clear this MRU list.

Outlook holds two different kind of MRU lists. Some are tied to the general Outlook configuration of the logged in user and others are tied to the specific mail profile Outlook has been started with.

To clear either MRU list, you can simply delete the corresponding registry key when Outlook is closed. If you are not comfortable editing the Registry yourself you can use OutlookTools instead.



Profile MRU

MRU lists that are kept in the mail profile are stored in the following Registry key:

  • Outlook 2013
    HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Outlook\Profiles\profile name\0a0d020000000000c000000000000046
  • Outlook 2010 or previous on Windows NT, 2000, XP, Vista, Windows 7 or Windows 8
    HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\profile name\0a0d020000000000c000000000000046 
  • Outlook 2002/XP or previous on Windows 95, 98 or ME
    HKEY_CURRENT_USER\Software\Microsoft\Windows Messaging Subsystem\Profiles\0a0d020000000000c000000000000046

Note: Replace profile name with the name of your mail profile (by default it is called Outlook).
