Hi; Is Exchange 2007 Active Sync support custom port deplyment, instead of default 443 port for internal and external users access? If so, how to configure the new custom port in Windows Mobile 6.1 under "Server address" Active Sync?

Hi MMO, As per my understanding, we can not change the default port 443 to custom one for ActiveSync.

Areyou saying that, IIS in E2K7 serverwill not permitus to change the defaut port of 443 to another custom port such as 57786 port? And Windows Mobile 6.1 Active Sync only recognise port 443 for communicate with IIS in E2K7 server?

Hi, As there is no way to configure ActiveSync port in device, we could not customize the EAS port in the Server. Thanks, Elvis

Thank for clarification.
