Outlook 2016 Autodiscover for Non-Domain Joined Computers

Outlook 2016 requires Autodiscover to connect to Exchange, which can make it difficult for users on non-domain joined PCs.

Meaning: unlike previous versions of Outlook, there is no manual setup for Exchange accounts.
If some of your users have personal machines that they use to connect to Exchange, there's a registry fix (hack), that will bypass that domain check and allow them to configure their Outlook profile.

First, download the Outlook2016.reg key file from my Google Drive.

**Note** You can also create the reg key manually:

Open Notepad, and paste the following into it:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\AutoDiscover]

"ExcludeHttpsRootDomain"=dword:00000001

Close and Save the file as Outlook2016.reg

Once you have downloaded or created the registry key, we'll need to import it.

Simply double-click Outlook2016.reg

Click Yes that you are sure you want to continue.

Click Ok.

Now try to set up your Outlook profile to connect to your Exchange environment.
