Sync Windows Mobile 6.1 with Exchange Server

[rhauer]

Thank you. However, my situation seems a little different. Although, like everybody else my IT dept won't help and I cant understand why MS can't talk to MS. Oh well. My issue.

My certificate was issued by GoDaddy. Once in OWA I can download to CER files. I put them on my memory card and install them through explorer. They both install successfully. Then when I go on my handheld to activesynch to install server info all goes well. I get a messgae about security, I press yes and it sync perfectly.

Then the problems start. If the phone is turned off, or the batter dies, and sometimes for no reason (every two days or so), it stops syncing and I get the error message that my certificate is not valid. The only thng I can do is go into Active Sync and delete the exchange server account and then reinstall.

ANY IDEAS at all would be greatly apprecaited.
