Trouble with OST

[barrycuda72]

Office 2007 Exchange 2003 SP2.
Have several clients that are having issues getting the OST to sync
correctly. The are NOT running in cached mode and no additional add-ons are
enabled.
Did a fresh install and created a new OST file and still having the same
issue. There are no errors, example if you are online you may have 25
messages in the inbox
you synch and work offline you may only have 20 messages in the inbox

Ok Found part of the problem in the Send/Receive Group settings the Exchange
account was not included in the group to sync.
I know it was configured before. What possibly could be changing this???
