ActiveSync requiring SSL question
Posted on 2007-08-02
I am running Exchange ActiveSync and using RPC over HTTP/S, as well as OWA. I noticed that OWA requests were being accepted using HTTP instead of requiring HTTPS. So I looked at some documentation, tested and found that when I hit the "require SSL" and "require 128 bit" on the Exchange virtual directory, it breaks the EAS and I get the 3029 Event ID in the Event Viewer. Playing around a bit I also noticed that when I just require the SSL withouth the 128 bit, EAS works properly and OWA only responds to HTTPS requests.
So my configuration in IIS is this: on the RPC directory it has require SSL and 128 encryption. On the Default Web Site, OMA, and Microsoft-Server Active Sync directories, there is no requirement for SSL. On the Exchange directory there is require SSL but no 128 bit encryption.
Is there anything adverse to running it this way? My RPC works, HTTPS-only works, and Active sync works.
