Scenario: When adding a new mail profile, it automatically completes and does not display the Add Mail wizard for a different account

Scenario:  You want to add a new mail profile for a different account in Outlook. When adding the new mail profile (via Control Panel OR via “Choose Profile” when opening Outlook),  the new profile automatically completes and adds YOUR email account, and it doesn’t display the “Add Account” wizard where you can enter in a different email account.

Cause:  This is by design in Outlook 2016 through the use of ZeroConfigExchange.


If you wish to disable this feature all together:

Navigate to one of the follow keys: 




Disable the ZeroConfigExchange DWORD by setting the value to 0

If you wish to keep this feature enabled but allow the wizard to pop up for additional accounts, you can leave the ZeroConfigExchange DWORD enabled (meaning it has a value of 1) and you can add the DWORD ZeroConfigExchangeOnce

Navigate to: HKEY_CURRENT_USERSoftwarePoliciesMicrosoftOffice16.0OutlookAutoDiscover

Add ZeroConfigExchangeOnce and set the value to 1
