Need help setting up iPhone 3.0 and ActiveSync with Exchange 2003 SP2 single server configuration. I have started the process with assistance of other references and various MS KBs. Not sure if I'm heading in the right direction since I've be around the process tooo many times and still no luck.
Don't assume anything is correct or valid at this point, since some information may have been for specific cases. So to that end where shall we start?
I can give you this for now... The tool at https://www.testexchangeconnectivity.com
still errors on FolderSync command test failed. HTTP 403 forbidden response was received... also receive an Event 3005 Unexpected Exchange mailbox Server error: Server: ... Status code 
Is this a permission error?
The phone appears to be setup correctly but only produces messages. Cannot Connect to Server or something like that. (I do not have immediate access to the phone) so I am depending on the MS web tool above (hopefully it works).
Also, have and SSL certificate from GoDaddy.com still not sure if that is correctly installed/setup...
Again, please ask what you need as I have done/un-done so much that triple checking can't hurt.
Thanks in advance, I know you can do it!
