Hmm, no. That's about the deleted emails. This is about the read ones. He reads an email in outlook, and it shows read on BB. Thanks though!
Hmmm, I think that I may have found something. I don't know, but maybe...
Notes on BES batch processing delays that may affect how quickly reconciliation is performed: The wireless email reconciliation feature implemented between a handheld and a BlackBerry Enterprise Server (BES), processes requests in batches. As messages are handled (read, deleted, moved, etc.), these modifications are queued up and sent to the BES for batch processing. Batching delays the wireless synchronization of folders and message status while the information is being queued and the batches are being created. The batching process is designed to regulate the amount of wireless traffic the BES has to process so that it does not become inundated with requests that the worker threads need to process. Heavy wireless traffic from wireless email reconciliation, as well as other wireless features, can cause the performance of the BES to degrade and may result in noticeable delays in reconciliation.
Does that mean that if he reads the email, (but doesn't delete it), that it should show as read on his BB after a short spell?
