SYMPTOMS

If you enter one or more friendly nicknames in your Personal Address Book or Outlook Address Book, Microsoft Outlook may fail with a Dr. Watson application error or a Quincy error.

CAUSE

If an earlier version of Outlook was installed and used on the client computer, the nickname file may be corrupted.

Outlook caches nicknames, which are words or names that are part of the display name of items in your Personal Address Book or Outlook Address Book. When you use words or names which are part of the display name, Outlook caches this information as nicknames in a nickname file. If you try to use a nickname that is stored in a corrupted nickname file, Outlook may not resolve it correctly, and it may fail with a Dr. Watson error or an application error.

WORKAROUND

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

Rename the nickname file and allow Outlook to rebuild your cache of nicknames.

The following registry key identifies the nickname file to be renamed: HKEY_CURRENT_USER\Software\Microsoft\Office\8.0\Outlook\AutoNameCheck NicknamePath = full path to nickname file
