iOS7 not syncing email with Exchange 2003 on internal network

On our iPads that use anything below iOS7, email works fine. Anything using iOS7 and above, the iPads will not sync email on our internal network. If I am using WiFi outside of the business, it works fine. For example, at home, on WiFi, the iPad sync's the Exchange email fine. Inside the office, it will not.

We have removed/added email accounts but did not work. I did read something about activesync not working correctly with iOS7, but said that it was an issue with iOS7.

your exchange server is 2003 so you are using active-sync , I bet the problem is dns OR firewall block related, please try setting dns to 4.2.2.2 on one of the devices see if it helps..

So is the DNS only an issue with iOS7 devices, since iOS6 works?

And we have tried 8.8.8.8 and 8.8.4.4 for DNS and no luck. Will try 4.2.2.2 today.

Is the internal domain name the same as your Public Domain Name?

Yes. Both internal and external domain names are the same.

do you have a certificate for active sync or do you use http?
what happens when you browse to the active sync address from one of the devices, do you see a certificate related error or anything?

No errors, just the spinning wheel while trying to sync.

And just on iOS7 devices. iOS6 devices work great.

Do you have an internal DNS pointer to the FQDN that you are using on the Devices pointing to the Exchange 2003 server?

Are you entering domain name and username in the settings?

How long is your domain name (before the full stop)?

Okay - sounds like an iOS7 problem.  What iOS version are the iPads on?

If you select Settings> General> About on an iPad, what does the Version say?

Mine is currently on iOS 7.0.4 and works happily.  It may be that the iPad's need updating before they will work.
