Windows Mobile 5 ActiveSync - Changes not synchronised back to server
Posted on 2006-11-13
We have just configured an Exchange 2003 SP2 Front-End Server for Outlook Mobile Access (OMA - ActiveSync over GPRS).
New mails are sent to the device as soon as they arrive in the mailbox - great ;D.
When an email is read on the device, or is deleted on the device, the change is not replicated back to the Exchange Server until you do a manual send and receive.
I have configured OMA at multiple customer sites over the last few months and have not had this problem before.
I have two theories, both of which could be completely wrong but I will note them anyways as they are both unique to this deployment (like the problem is unique to this deployment).
1) The device we are using this time is a Vodafone UK Palm Treo - this doesn't have a "Comm Manager", which seemed strange to me as all other WM5 devices I have worked with before have had this, but the DirectPush (if this is indeed what it uses), seems to work anyway.
2) The Exchange server is a front end server for several "real" exchange servers behind the scenes. The desktops do not connect to this server as the mobile device does. Could this be the problem?
All suggestions very welcome and thanks for taking the time to read my question,
