Q: How can I clear the Microsoft
Office Outlook auto-complete
address cache?
A:Outlook has an auto-complete cache to help fill in recipient
information when adding recipients. If you want to delete this
auto-fill cache, you can delete individual items or the entire
cache. You remove individual items by typing an address on
the To line of an email, and when the auto-fill suggestion is
displayed, press the Delete key. To delete the entire cache,
stop Outlook, navigate to the %APPDATA%\Microsoft\Outlook
folder (type this in Explorer address bar), and delete the
Outlook.NK2 file. Restart Outlook.
