I have setup an Exchange cluster and am running OWA with SSL enabled. Everything was running fine and I have set up almost 100 users on this new email system.
Whenever some users try to connect to OWA via https://server/exchange
they are prompted for the certificate and then asked for their user name and password. When the name and password are entered correctly they are forwarded to the HTTP/1.1 503 Service Unavailable page. If they click refresh OWA comes up as it should.
I've searched for solutions and I could only find one that says to uncheck "Enable anonymous access" for the ExchWeb in IIS. This appears to have worked but then users would get to the OWA main screen and the email list would freeze on "Loading" or would finally error with
error line: 1038
invalid procedure call or argument
This was only in Internet Explorer, Firefox worked fine.
Please HELP, the boss is not happy :(
