Clear Outlook AutoComplete Cache

This tip is especially useful if you've sent an email to someone, but accidentally misspelled their email address. Clearing the cache will delete this entry and allow you to create another entry that is correct.

1. Quit Microsoft Outlook.
   
2. Click on Start -> Run
3. Type in %appdata%\microsoft\outlook.
4. Delete the file [profile name].n2k.
5. Relaunch Outlook.

Outlook will then create a new .n2k file to store your cache.
