Outlook 2003, and earlier, has a "forms cache" bug. Clearing the
cache usually fixes it. Choose Tools | Options | Other | Advanced
Options |
Custom Forms, then click Manage Forms, then Clear Cache. If simply
clearing
the cache doesn't fix the issue, try the other steps detailed at http://support.microsoft.com/default.aspx?scid=kb;en-us;836558
The bulk of the forms cache issues in Outlook 2003 are fixed in Service
Pack
1, so you should also install Office 2003 Service Pack 1 as well as BCM
SP1.
