Changing the SSL port number used by OWA

A question was asked “How can I change the SSL port# used to access OWA?“. This response was provided by Ray Fong (assuming we want to change the port# from 443 to 10001:

1. Go to Exchange System Manager, Protocols -> HTTP. Right-click New HTTP Virtual Server.
2. Specify “Exchange OWA 10001” for the name.
3. Click Advanced, modify, change the port from 80 to 81. SSL port is not available, that’s OK.
4. After you click OK and Applied, go back to the same screen. Now remove port 81 and specify 10001 as the SSL port. Click OK all the way.
5. Follow the steps below to force the DS2MB replication.

ID=”61472″   (<—- This one)
Value=”53322″
