Exchange 2010 Activesync not working

I recently moved mailboxes from an Exchange 2003 server (on SBS) to an Exchange 2010 SP3 server (on Server Standard 2012). Everything appears to be working fine except the users phones cannot connect using Activesync, It continues to ask for a password and cannot verify the server. SSL is enabled and the certificate works fine with OWA. I don't see any errors when connecting and the Exchange Remote Connectivity Analyzer shows a successfully connection. The feature is enabled on the mailbox(s) as well. Any ideas?

Basic authentication is enabled and no HTTP redirect.

Router port forwarding updated on the router?  I assume this was done otherwise email wouldn't fire up.  Active sync enabled on the new exchange server for the mailboxes?

Feature is enabled on the mailboxes as well as HTTPS is opened.

There were two problems:

1. The account I was testing with was an admin account with Disabled Inheritance. Thanks for the heads up.

2. After reviewing the W3SVC logs I noticed the users weren't authenticating with a domain. I then added the domain to the Basic Authentication settings.
