What is causing my Outlook to freeze when I try to send messages?

I have a SBS 2K3 domain.  We are using this server as our Exchange Server also.  All in the domain works well with the exception of One PC.  The PC in question is loaded with Windows XP Professional.  The problem I'm having is this; on this one PC a particular user can't send /receive any email.  A new email can be opened however when the user clicks send Outlook freezes.  The same is true when attempting to FWD and/or Reply.  If this user logs into another machine it works fine.  If the user logs in through OWA it works fine.  Other users can log into her machine and they have no problems.  This user has local admin permissions for her PC.  I've verified that the PC was up-to-date on all of its service packs and patches.  Finally I've reinstalled Outlook.  None of the above have fixed my issue.  Any assistance is greatly appreciated.  Thanks in advance.

    is this user configured to use cached mode?  if so, uncheck use cached mode and then delete the OST file manually.  try sending email. then re-enable cached mode.

    in outlook go to the user account properties.  there is a checkbox that says "use cached mode".  if it is checked, uncheck it and close out of outlook.

    the ost file should be:
    c:\documents and settings\%username%\Application Data\Microsoft
