Exchange 2007 SP3 - iPad suddenly can't connect to Exchange server


For some reason an iPad suddenly stops connecting to an Small Business Server 2007 SP3.
The OWA environment works fine, i can open it with any browser on my computer as also in the iPad.

I deleted the account on the iPad and tried adding it again, but then i receive a message that it could not verify the account.
Tried every way of user credentials, but nothing works.

Also reset the network settings on the iPad, but that didn't fix it either.
I tried my own iPhone and iPad, but i receive the message also, while i can connect to other SBS 2007 servers or Office 365 environments.

Does anyone have a clue what this could be?

We came across issues with specific characters ("£") preventing activesync working on Android devices, might be worth changing the password in the first instance and / or maybe deleting the Activesync partnership and recreating.

The password doesn't contain any special characters and i have created a new account on the server with no mobile devices attached attached at all. This is not the solution.

go to  and enter the accounts credentials and see in the output what cause the problem, today I faced the same issue and when I proceeded with the above I saw in the output "denied by policy" then I solved the issue

The weird thing was, that the error on testconnectivity was not complete and couldn't point me to a solution.

I have recreated the entire IIS / OWA part and now it works again.
Why it suddenly stopped working is a mistery, but for me this one is solved.

Because you 2 have tried helping me, i will devide the points between you 2.

Thanks for the effort.
