You have an environment with multiple domains on exchange 2010 server using Microsoft windows server product.

Scenario:

Domain A.com

Domain B.com

Domain C.com

Domain D.com

Domain A.com was migrated to office365
with specific user objects in Domain A organization
Exchange server still remains in customer environment
User cannot setup outlook due to autodiscover is still pointed to exchange 2010
Change dns container for Domain A.com and also host file on user machine to point to autodiscover.outlook.com but still no luck
when setting up outlook the user still retrieve exchange settings from exchange in house.
Remote user can access and setup outlook just fine with no problem because their machine is not talking or communicating to internal AD

How do we solve this ?

Customer have 10,000 users and need this fix ASAP.

Here is the SOLUTION:

<MANUAL PROCESS>

Navigated to the location in the registry editor in usr machine to do this manually :

HKEY_CURRENT_USER\Software\Microsoft\Office\x.0\Outlook\AutoDiscover

Note: x.0 in the above registry path corresponds to the Outlook version (16.0 = Outlook 2016, 15.0 = Outlook 2013, 14.0 = Outlook 2010, 12.0 = Outlook 2007).

Created a DWORD with value 1 and name ‘ExcludeSCPLookup’
Restarted the machine and configured the Outlook profile.
Ran ‘Test Email AutoConfiguration’ wizard and found Outlook is connected to the Office 365 user mailbox.

Download this zip file attached and run all 4 bat files per user machine and then restart
Ran ‘Test Email AutoConfiguration’ wizard and found Outlook is connected to the Office 365 user mailbox.

Download this zip file attached
Create a GPO and add the files and point it to the users or machine when logged in or logged off.
Createa GPO to log off the use instead of restarting the machine
Ran ‘Test Email AutoConfiguration’ wizard and found Outlook is connected to the Office 365 user mailbox.

All Done !
