Re: Sync Windows Mobile 6.1 with Exchange Server

I for one do not have our exchange server published onto the web and I access it through VPN. So that setup in a WM6.1 phone is a little bit more tedious as you have to setup a work VPN AND an exception rule under connection settings/advanced to the internal address that I use to reach my exchange server through my internal LAN. That way whenever Active Sync tries to sync WM will detect that I'm trying to use that address and activates the vpn automatically for the duration of the sync. The only drawback that it takes a while for the first few active sync timeouts to actually come into effect because it starts sending packets to request data while the VPN is connecting. During this time the phone won't reach the exchange server and will wait for these packets to timeout before trying again. When they timeout active sync proceeds normally, this usually takes about 4 minutes. I haven't looked into lowering this timeout but I think that could be a good project for tonight.
That maybe why it worked for you by just installing the certificate. I do not use a VPN and I sync OTA using GPRS.
