I have a problem on SBS2003 where ActiveSync does not work, with event ID 3005 logged several times when a client tries to connect.
The Exchange Remote Connectivity Analyzer says: "Exchange ActiveSync returned an HTTP 500 response."
Outlook Anywhere (over RPC) and all other aspects of IIS / Exchange are working correctly.
I have already tried everything listed at http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/A_1798-Exchange-2003-Activesync-Connection-Problems-FAQ.html
to no avail, and have seen many other questions relating to this error, but none of the answers (that I have read) help in this case.
Can anyone offer any advice before I have to raise a case with Microsoft?
Thanks in advance
