Outlook 2k2/Exchange 2k3 Custom Form Search Problem

[Adams999]

We run Outlook 2002 on WinXP machines through Exchange 2003 on a Windows 2003 standard server. We schedule appointments in Outlook Calendar using a custom form whcih includes the user defined field "Client Name." I can open Advanced Find and run a search using this field, but when I save the search and reopen it, the field appears as "

http://schemas.microsoft.com/mapi/string/{00020329-0000-0000-C000-000000000046}/Client Name."

When I remove the field from the Criteria list, it disappears. I have set up full text indexing per Microsoft KBA 319436, but I still can't save the search with the field intact.
