Joe, I'm missing new messages too. The last three four days. Although everything seems normal, There will later be some unread messages and I can't figure out why I missed them--there were no anomalies to explain it.

Can you tell me how you know you didn't see some new messages when doing a ReadAllNew regularly?

You say later there will be some unread messages. When you actually see these "unread" messages later, how are you seeing them?
