(FAQ) What port numbers does ActiveSync use?
What port numbers does ActiveSync use?
ActiveSync requires WorldClient to use port 80 for non-secure (SSL) HTTP connections, and 443 for SSL/HTTPS connections, for both the built-in web-server or running under a third-party web-server like Microsoft IIS. This is an ActiveSync implementation requirement, so it cannot be changed to a different port.
Note that ActiveSync support requires MDaemon Pro.
