Pocket PC Forum / End Users / ActiveSync / May 2006HTTP1.1 501 Error ... Exchange Sp2 & WM5
Greetings I have a WM5 phone and Exchange w/sp2. When I try to sync over the air, I get an HTTP1.1 501 Error on the phone and a 8500200c error in AS. USB sync works fine. I am forced to use a port redirection from 80 to 8080 to get to my Exchange Server from outside, so that could be one part of the problem. Is that it? Anything else? FWIW I cannot access OMA either. Thanks in advance. Ken >Greetings > [quoted text clipped - 7 lines] > >FWIW I cannot access OMA either. If you have redirected the Exchange virtual directory itself to port 8080, then that is probably the problem - ActiveSync and OMA connect back to the Exchange virtual directory on port 80 (the connection to the server from the device is on port 443, for SSL connections). You need to find a better way of redirecting the port - possibly use a firewall on or before the server (to redirect traffic).

Actually, the router is in front of Exchange ... and it accepts traffic on 8080 and then sends it internally to 80. However, I suspect 443 is probably blocked as well, so the combo of the two is most likely the issue. Unfortunately the ISP wants an additional $30 a MONTH to upgrade to a "business" account that unblocks the port!! Thanks for the reply ...

ActiveSync communicates on port 443 for secure communications, and I'm pretty sure most of the stuff is set to port 80 otherwise (ie when you click on a link it defaults to port 80).
