I've recently installed IMail Server 188.8.131.52 and am attempting to get Exchange Active Sync working with it.
On the server I can see it is enabled and licensed for 25 users. I have my own account enabled for that feature in order to test.
I try to configure it on my iPhone 5S as shown here:http://docs.ipswitch.com/_Messaging/IMailServer/v11/Mobile/MobileSync.pdf
however I keep receiving a "Unable to verify account information" when I hit "next" on the iPhone to complete the setup.
I know I have the correct server IP and other info including my username and password. Windows Firewall on the server is off for the internal network and I'm trying to connect via the internal network, not externally.
If anyone has ideas on how I can get this working please let me know. Thanks!
