Clear the Most Recently Used lists

For certain actions Outlook holds a list of recently used items so you have quicker access to them. In some case you want to clear this list.

Outlook holds two different kind of lists. Some are tied to the logged in user and others are tied to the mail profile. To clear them you can simply delete the key when Outlook is closed. If you are not comfortable editing the registry yourself you can use OutlookTools instead. The following tables show an overview of MRU lists that Outlook is keeping and where you can find them in the registry. To open the registry editor click Start-> Run and type regedit

Profile MRU

MRU lists that are kep in the mail profile are kept in the following key;
HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\profile name\0a0d020000000000c000000000000046
Replace profile name with the name of your mail profile (by default it is called Outlook).

If you can’t find this key look for the following key instead;
