My CEO just got a new iPad, and she has instructed me that I have to get it synchronizing with our Exchange server. I have not tried to use Active Sync on this server until now, and am having difficulty.
I have a single Exchange 2003 STD server, behind an ISA 2006 server.
I have Outlook Web Access published through the ISA server, using forms based authentication on the ISA server.
Forms based Authentication is turned off on the Exchange server.
There is a certificate from Go Daddy installed on the Exchange and ISA servers – this seems to be working since OWA works fine.
I also have some users connecting using RPC over HTTP, again through the ISA server, and this also works fine.
I used the Microsoft Remote Connectivity Analyzer (https://www.testexchangeconnectivity.com/
) to test Active Sync.
I was getting an error using this tool which pointed me to this MS article:
This basically involves setting up an alternate virtual directory for Exchange that does not require SSL, and then adding a registry value to point to the new virtual directory.
I followed those steps and got the following error:
“An HTTP 403 error was received because ISA Server denied the specified URL.”
Looking in the ISA log I saw that the MRCA tool was attempting to go to the default virtual directory “Microsoft-Server-ActiveSy
nc”. So I went into the ISA server rule and set external path to “/Microsoft-Server-ActiveS
ync/*” and the path to the new virtual directory “/ExchActiveSync/*”
Now the MRCA tool is giving me the following error:
“Testing of the OPTIONS command failed. For more information, see Additional Details.”
And gives me a link here which talks about ISA Server 2000, third party reverse proxy servers, and having “URL Scan” installed – none of which apply.
On the ISA Server I get:
Denied Connection ISASERVER 9/22/2011 4:16:58 PM
Log type: Web Proxy (Reverse)
Status: 12239 The server requires authorization to fulfill the request. Access to the Web server is denied. Contact the server administrator.

Anyone have any suggestions?
