Exchange ActiveSync Issues


I have setup Exchange ActiveSync in the following environment:

WIndows 2003 Domain
Exchange 2003 Service Pack 2
Windows Mobile 6.1 Device

I have enabled Activesync in Exchange system manager.
Outlook Mobile access and web access is working from the device but when I try to use Exchange Activesync from the device, the following is logged on my exchange server (application log):

Source: ServerActiveSync
Event ID: 3005

Unexpected Exchange mailbox Server error: Server: [Our Mail Server DNS Name] User: [User Email address] HTTP Status code: [501]. Verify that the Exchange mailbox Server is working correctly

Please assist, Ive tried lots of things but I cant seem to sync the device with the server.
The purchased owa certificate seems ok.

Does the user have an email address in the default domain?
The default domain is the same as your Windows domain - domain.local for example. It doesn't have to be the default email address.

You could also test it with the Microsoft test site and a test account.

Yes the user has an email address in the default domain. (and AD user account)

eg username is
default domain is

Just tried the weblink test:- get as far as
 Http Authentication Test failed

Authentication method Negotiate is enabled but is not an allowed Authentication method for this service.

Any pointers?


Since you are using a certificate, can you confirm if you have enforced "Require Secure Channel" on the Exchange virtual directory under IIS Mananger or if you are using form based authentication for OWA ? if yes, then you will have to follow the KB article

If you are not using the settings as mentioned above, then you need to ensure the Exchange Virtual directory has "Windows Integrated Authentication" enabled under IIS Manager.

Require Secure Channel is enforced and form based authentication is enabled for OWA
I will give the kb a try later and let you know.

Does require Secure channel mean ssl cert required?  I have one purchased from an external company.

I have tried the kb817379 but appear to have the exat error. Even after recreating the exchange-oma virtual directory.

Using this website, 
I get the following error code:

Attempting FolderSync command on ActiveSync session
  FolderSync command test failed

After some tweaking the error code is now HTTP Status code: [400]
instead of HTTP Status code: [501].

Any ideas?
Hi wk6838

I have the exact same issue as you - got the same results from too.  I'm still getting a 500 error though and I'm sure I've tried all the kb's at least 10 times each!  It's driving me mad!

Did you managed to get to the bottom of this?  Any suggestions would be much appreciated.

This has been sorted, after a lot of troubleshooting it was down to the default web site config in IIS. In Web Site tab, the IP Address was reset back to (All Unassigned) from the IP address of the mail server.

I dont know what the significance of this setting is but this is now solved
