I've been struggling with my IIS exchange configuration for some time now, however I believe I'm almost there.  After weeks of fiddling I've managed to configure IIS so that OWA works perfectly, however OMA can be accessed via http://server/oma but does not sync with any mobile devices.

Event viewer is throwing back code listed below.

Any suggestions would be much appreciated.

That is usually caused by email address issues on the account. Do you have an email address on the account in your default domain? The default domain is the same as the Windows domain. It does not have to be the default email address on the account.

Hi Simon

Many thanks for your comment.  I apologise for my lack of understanding, but could you explain briefly how to check this?  

From what I think you mean:
We do have email addresses assigned to the accounts as when I log in via http://server/oma it prompts for the credentials and loads the data in the oma format...

Many thanks

Adrian

Has nothing to do with the way that you login.
Look at the properties of the user. On the email addresses tab there should be at least two email addresses

user @ example.com (The primary address)
user @ example.local (where example.local is your WINDOWS domain).

If your WINDOWS domain and EMAIL domain are the same then there would be a single email address.

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

Hi Simon

I've checked the properties of the user - it's exactly as you suggested, with at least two email addresses per user - user@example.com is the primary address.  I'm assuming that this is correct?

Does that happen for every user or just one?

It happens for every user.

When I use https://store.accessmylan.com/main/diagnostic-tools?pos=nav the following is returned:

ActiveSync detected, but not correctly configured. [HTTP 500: Forms-based auth enabled?]

For more detailed analysis go to https://store.accessmylan.com/main/activesync-detected-not-configured-500?utm_campaign=astest&utm_source=accessmylan.com&utm_medium=ActiveSyncTester-1.1.0.0&utm_content=ASTEST_ERROR_AS_500.

However I have tried all of the suggested and going over and over various KB's.  I've even re-created the VD's...I'm going mad!

I have no idea what that testing site is.
The main one to use is Microsoft's

https://testexchangeconnectivity.com/

The number of reasons for failures with this feature are usually quite limited. The most common one is to have forms based authentication enabled and/or to have require SSL enabled on some of the virtual directories. That will break the functionality of ActiveSync.
