First thing I would try is to clean up the forms cache.

To do so, follow these steps:
1. On the Tools menu, click Options.
2. Click the Other tab, and then click Advanced Options.
3. Click Custom Forms.
4. Click Manage Forms.
5. Click Clear Cache.
6. Close all open windows, and then restart Outlook 2003.

If the above does not work, try the following.

Deleting the Forms Cache File:
The Frmcache.dat file is the primary file to delete. The Frmcache.dat
file serves as an index of the individual forms that have been cached
on the computer. Use the following steps to manually delete the
Frmcache.dat file. In addition, these steps delete all of the cached
forms on your computer, which are stored in subfolders of the
Forms folder.

1.. Quit Outlook.
2.. Search the Hard drive (F3) to locate the Frmcache.dat file.
(Be sure to check in HIDDEN files on W2K or WXP.)
3.. Delete all that are found from the FIND window.
4.. Open Outlook.

When you restart Outlook, and use a form, the forms cache
is re-created.

When the error occurs, can the client access ANY public folders?
If not, check to see what GC the client is using. Is anyone else,
that is using that GC also having problems? Could it be the port
the client is hooked into, going offline for any reason?

Does this happen when the client tries to open a particular
Distribution List in their Contacts?
