Last night we restored our SBS 2003 server from tape after a disaster. At first, it appeared that the Outlook clients were working correctly and matched OWA - I sent and received from both with no problems. Today, users report not receiving emails in their Outlook, but if I check OWA, all is good. I can still send/receive in OWA just fine. Outlook says all folders synchronized, yet messages aren't showing up. The issue is not isolated to one version of Outlook, as we have a mix of Outlook 2003 and 2007.
