Reset the nickname and automatic completion cache

Applies to
Microsoft Office Outlook® 2003
Microsoft Outlook® 2002

Outlook maintains a nickname list that is used by both the automatic name checking and the automatic completion features. The nickname list is automatically generated while you use Outlook. If the nickname cache is corrupted, Outlook may not be able to identify recipients, may offer incorrect recipients when automatically completing the e-mail address, or may send the message to the wrong person.

Use the following steps that are appropriate for your version of Microsoft Windows to reset the Outlook nickname cache. After you restart Outlook, Outlook generates a new nickname cache.
