I am stuck trying to get Activesync working on my SBS2003 server with Exchange 2003. Client is getting an Iphone, so...I have been following alanhardisty post on Activesync Connection Problems. Got through all steps, made changes as needed to virtual directories, ran the test and get an HTTP500 error. Followed kb883380 to delete and recreate directories. Upon completion of kb883380, I reran the test and now got an HTTP403 error and my OWA was no longer working (not authorized message).
I redid beginning steps in alanhardisty post to again update virtual directory settings. Reran test - back to the HTTP 500 error and my OWA still getting Not Authorized. I tried disabling Forms based authentication and turning off SSL on Exchange virtual directory - same failure. I do not have EventID 9667 in the logs. I checked the ExchWeb virtual directory settings. Even ran Isinteg - found and fixed one error on mailbox store, and a couple on public. Still same results.
So, basically tried everything in the document. TestExchangeConnectivity results are attached.
The only error I ever see in the logs is eventID 3031 'The mailbox server does not allow "negotiate" authentication to its [/exchange-oma] virtual directory. I checked the kbs referenced in the eventID text - all ok.
Any other ideas or am I now down to calling Microsoft?
