Exchange 2003 Activesync - some accounts able to authenticate, some return a 403 error on Exchange and can't connect on mobile devices

The environment has 1 front end OWA/Activesync server and a 1 back end mailbox server where all the mailboxes are located. I have checked the Exchange Features of the accounts that can't connect and they are set identically allowing access at the account level. I have gone as far as copying an account that can access Activesync to a test account name and then trying to connect with the test account with no luck. I know Activesync is up and running as several accounts are able to sync up without a problem on various mobile devices. The SSL certificate is valid and we have no problems with any accounts accessing their email via Outlook Web Access. If I create a new account I get the same results. If anyone has seen this problem before or if anyone has any suggestions as to what steps I should take to troubleshoot, I would highly appreciate it. Thanks, Dan

I have since run the activesync test on the site below: https://www.testexchangeconnectivity.com/ The accounts that are able to access their mailboxes via Activesync on mobile phones pass the Activesync test. The accounts that fail are getting the following error when running the test: Attempting FolderSync command on ActiveSync session FolderSync command test failed Additional Details An HTTP 403 forbidden response was received. The response appears to have come from Unknown. Body is: <body><h2>HTTP/1.1 403 Forbidden</h2></body> Thanks in advance for any advice on how to resolve this. I'm off to search the net and see if there are any postings as how to resolve this. If I find anything, I'll post a response so others can benefit. Dan
