Exchange account verification failed

Trying to get new iPhone 3G to work with ActiveSync on an Exchange 2003 server. I type in all of the required info and get the following error: "Exchange account verification failed." ActiveSync is setup correctly on the Exchange server itself, port 443 is open on firewall. When the iPhone prompts me to add in info the the server, I put in the IP Address of our firewall because the name of our email server is not publicly published anywhere in DNS for spam control reasons. What else needs to be done to get this thing to work?

My company just upgraded to Exchange 2007 and after making a few adjustments to the info in the setup I was up and running fine. First, you might need to know the name of the server uses but if you are as lucky as me they will be using the default name(omg), before I just put in pllans.net in the server field but now I have omg.pllans.net, in the email field I put pllans\br92109@pllans.net, domain I have pllans, username and password with SSL "On".

I am running version 3.0 on my Iphone still due to the problems people have had after upgrading to 3.1.

Ok I got the answer for you guys if you get a 500 Error running ActiveSync Tester.

The reason you cannot connect your iphone is probably because NTLM Authentication is turned off on the mail servers IIS which hosts your OWA and OMA. This was our problem.

So as suggested in this forum i ran the ActiveSync Tester and failed with a 500 error which took me to this page for troubleshooting step by step guide. http://support.accessmylan.com/kb/article-56.html

i followed these instructions to the T and it worked. Didn't even need to restart the server. Note: creating the ExchangeVDir registry key has NO Space in between Exchange and VDir when creating the registry Key although the instructions say to use a space in it. It should look like this -> ExchangeVDir exactly with Case Sensitivity

These instructions basically set the server's OMA to use different login and authentication methods then OWA, this way, you can use .net or other login methods for OWA and have OMA use NTLM and Basic Authentication which apparently the iphone exchange active sync requires.

Hope this helps,

thanks all for leading me to ActiveSync Tester, i would have never have found the answer if it weren't for that
