Unable to verify account information

new customer, exchange 2013, windows 2012, trying to setup iPhones, used the ActiveSync opton, have verified server info Get-activeSyncVirtualDirectory |fl name, *url*, 

continue to get unable to verify account information,

looked for IP address in the latest w3svc1 log file, but did not record it.

from Outside I am able to use the same URL to successfully use OWA.

I have used multiple user accounts, and multiple phones.

using the URL I received from above I ran:

[PS] C:\Windows\system32>Test-ActiveSyncConnectivity -URL https://domain.org/Microsoft-Server-ActiveSync -mail
boxCredential (Get-Credential administrator@domain.org)
