Setting up OWA on an iphoneiphone 4

Hello EE. I am having a hell of a time trying to get one iphone4 user to to access OWA on Exchange 2010. I was able to successfyully set up 3 others with no problem. It keeps giving me "Exchange Account Unable to verify account information."
The only difference between her phone and the others is the OS is running 4.2.1 and the others are running 4.1. Inheritable permissions is checked on her AD profile. I was getting event id 1503:

 Exchange ActiveSync doesn't have sufficient permissions to create the "CN=User,OU=XXXXX_XXXXX Administrators,DC=MHACS,DC=local" container under Active Directory user "Active Directory operation failed on MHAS.MHACS.local. This error is not retriable. Additional information: Access is denied.
Active directory response: 00000005: SecErr: DSID-031521D0, problem 4003 (INSUFF_ACCESS_RIGHTS), data 0
Make sure the user has inherited permission granted to domain\Exchange Servers to allow List, Create child, Delete child of object type "msExchangeActiveSyncDevices" and doesn't have any deny permissions that block such operations.


After checking allow inheritable rights in security tab I stopped getting that error but I still can not sync the phone. I tried with and without SSL. I do have a valid SSL ceert from GoDaddy. The other 3 phones gave no problems.. I have Exchange 2010 running on Windows 2008 R2 standard with a DC running Win 2008 R2 Enterprise. My luck she happens to be an Executive Administrator and is a domain admin as well. Any help would be appreciated.

You have verified that ActiveSync is enabled for the mailbox in exchange?

Can the user use the web browser to access OWA through the phone?

Yes on both counts.

Are you adding /owa to the end of the Fully Qualified Domain Name that you are configuring your iPhone with?  If you are - you should not be - you only should be entering something like and not

FYI - OWA is Outlook Web Access and has nothing to do with getting mail to an iPhone.  What you are referring to is Activesync.
Well I am trying to configure the iPhone to get email. Where it asks for the server i put the OWA link with the /owa. I will try it without it
With Activesync - you Never add anything after .com and if anyone tells you otherwise, they are wrong!
So what should I be adding when trying to configure email on the iPhone?
I tried it without anything after .com but no change
Email Address: users email address e.g.
Server: Whatever the certificate name includes e.g. or or whatever you have configured
Domain: Internal Domain Name e.g., internaldomain (not internaldomain.local
Username: Users username e.g., user
Password: Users network password
Description: Whatever takes your fancy to describe the account on the phone.
thats way i tried it and no go
Okay - can you please run the Exchange Activesync Test (Not Exchange Activesync Autodiscover Test) on and port the results (hiding your domain name / IP Address).

Please run one for the working user and one for the non-working user and post both results.


I do not have access to the wtestorking one but this is what I got from the non working one

Sorry - that doesn't work - you can copy / paste the results but the .htm page doesn't show anything other than the Initial site page.

Bummer. It would not let me copy and paste. It complained about browser sttings
Can't you click on Copy on the results page and then paste them to EE?
It won't let me copy. It complains about the security settings in my browse. Let me try something different.
The last part of the test failed. this is what it said.

An ActiveSync session is being attempted with the server.

   Tell me more about this issue and how to resolve it

What browser are you using?
Okay - you say you have checked the Inherited permissions - please uncheck - apply - then re-check and apply - then test again.
I checked it earlier but when I went back and checked it, it unchecked again.
I checked and it runs. How can I keep this from happening?

Yes, the user is an admin
In that case, please read the links I have provided in my last comment.
Thanks for the help. My problem has been resolved thanks to your useful posts.
Great news.  Was it the inherited permissions?
Please don't forget to close down the question if you have finished and the problem is solved, which you have said it is.
