Microsoft Windows(TM) Messaging.... Error

Greetings folks. Does anyone have a fix for this error:

Microsoft Windows(TM) Messaging Subsystem Spooler has encountered a problem and needs to close. We are sorry for the inconvenience. :mad:

(No the smiley is not a part of the error message, lol.)
This is a pc on a LAN in a workgroup running Windows XP and Office 97' (Yes we have plenty of licenses for Outlook 97 but we are too cheap to get new licenses for the 2003 software). This allegedly happened when no changes were made however it didn't happen on my pc so I'm working on the word of one of the sales people at my job. Anybody have any insight on any new hotfixes or other issues that may fix this? Thanks.
