Exchange 2007/2010/2013: ActiveSync asking for Domain Name on Mobile Device

Issue: 

Post migration from Exchange 2010 to 2013, mobile devices are not connecting with out domain name.

 

Cause:

Unable to query domain and authentication failed.

 

Resolution:

There is no solution for it. It is by design as there is no field for the domain name in the Exchange Active Sync configuration.

 

Workaround:

1. Login to the CAS server

2. Open IIS Manager

3. Expand Default website

4. Highlight the Microsoft- Server-Activesync and select authentication on the right side

IIS1

5. Go to the properties of the authentication

6. Right Click on Basic Authentication and click edit.

 

7. Type backward slash in Default Domain “”  and type your domain name in the Realm

IIS2

8. Reset IIS by the cmd – “IISRESET /NOFORCE /TIMEOUT:120”

    I have been battling a post SBS migration tasks with an exchange server that is attached to a different domain than the email address (domain.local vs domain.com). This has helped with the mobile device connectivity greatly.

    Thank you!

    I’m prepping for migration from 2010 to 2013 this summer; which domain name needs to be entered here? The local (abc.lan) domain or the external domain (abc.com)? If this is a hybrid environment with on-premises 2013 server and Office365 does that change this at all?

    This is a domain for authentication so in which AD domain your users will login should be entered here. We need to use netbios name of the domain.
