We are using CRM Online 2015 Update 1. We have ADFS (3.0 Server 2012R2) Setup for SSO Access to Office 365 and CRM for our Domain - Users are Synched with Active Directory (Basic ADFS Server / ADFS Web Proxy Setup).
Web Access inside or outside the Organization to CRM from any device (Windows Workstation, iPhone, iPad, Android Device, etc) works fine. Cool!
But, when using "Dynamics CRM for Phone" App on iPhone 6 (version 9.2) (Or "Dynamics CRM for Tablet" App on iPad), I just get presented with the Web Address screen ("Enter your company's Microsoft CRM Web Address" page) after my username ( username@federateddomain.com ) is entered in the Logon form. If I have MFA setup in Office 365 for a CRM User, they are presented with the Error "You're signed out" "You'll need internet access to continue" after the Username is entered - Redirection to the Corporate Logon page does not occur.
Errors in the Log Dump reference "[ERROR]: Telemetry Reporter: End Point Not Set. Dumping Event Data....."
Cloud Based Accounts WORK fine - Federated Accounts synched to Active Directory DO NOT WORK. Another strange Tidbit - Windows Phones seem to work fine.
We HAVE run the PowerShell commands for Add-AdfsClient (for both "Dynamics CRM Outlook Client" and "Microsoft Dynamics CRM for tablets and phones").
Really scratching my head on this one - Microsoft Support has been no help so far. Not completely ruling out Firewall settings - But have limited access to Firewall configuration - Told we have everything open to Microsoft Sites. If instructed specifically what to open or what to look for would be extremely beneficial if it is recommended to go down that rabbit hole.
Thanks in advance.
