I have a client who just got 2 Ipads. And I tried to sync their email to them. They have never used any moblile devices to connect to their Exchange server so it may be something on their server I have over looked but I cannot get them to connect. I also have my Iphone and cannot connect it to their email system though I can connect my phone to my email.
The MX record is correct and resolves to the right Ip address
The appropriate ports on the firewall are open
I have tried the text exchange activesync Microsoft website and everything checks out in green
I downloaded the Active Sync tester and ran in on theserver and it says its fine
On the Ipad I add the account and it gets the check marks next to contacts, calander, and etc but when I open the mail on it and my iphone it says
'Cannot get mail
The connection to the server failed.
