Setting Up Outlook 2003 Cached Exchange Mode Accounts

Often this is caused by a synchronization that is not occuring
correctly.

Also check to see if the clients are setup for "Roaming Profiles".
I would also try deleting the OST files (in case they are corrupt). These
files can be deleted without a problem, they will simply recreate
themselves when you log back into Exchange using Outlook.

but

Windows XP Sp2
