I allow myself to do this post in order to have your help. I am currently looking for a solution to automate the addition of a secondary mailbox in Outlook 2016. I saw a lot of stuff including the "zeroconfigexchange" registry tool however I failed to implement it because it looks like I don't have the registry values (screenshot attached). Can you help me please?

Do you mean the ZeroConfigExchange?

Based on my test and research, our clients don't have this registry key by default and we need create it in the following locations:

HKEY_CURRENT_USER\Software\Microsoft\Office\xx.0\Outlook\AutoDiscover(xx represents the current Office version such as 16.0)

HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\xx.0\Outlook\AutoDiscover

Then change the default profile with a new name different with existing ones and create a new profile for this new name in registry key:

Default Profile Setting: HKEY_CURRENT_USER\Software\Microsoft\Office\XX.0\Outlook

New Profile: HKEY_CURRENT_USER\Software\Microsoft\Office\XX.0\Outlook\Profiles

More details about this process: ZeroConfigExchange

Because you are using Outlook 2016, you could use the following .reg file to create these registry keys(Before running them, please backup the original keys and don't change other non-related ones.):

Windows Registry Editor Version 5.00
    
[HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Outlook\AutoDiscover]
"ZeroConfigExchange"=dword:00000001

[HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\office\16.0\outlook\AutoDiscover]
"ZeroConfigExchange"=dword:00000001

[HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Outlook]
"DefaultProfile"="ZeroConfigExchange"

[HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Outlook\Profiles\ZeroConfigExchange]

If you want to apply the ZeroConfig on domain-joined clients, GPO is suggested.

  • Thank you for your answer @Ivan_Wang ! I have executed your .reg file that you sent me. However now it is the part profile which does not seem to be functional. I did create the values ​​(see screenshot) but I do not have a test profile then which is implemented in the application. – Yarka Sep 30 '21 at 08:33
  • Did you login to windows with a domain account? – Ivan_Wang Sep 30 '21 at 09:04
  • No i'm login with a local account. – Yarka Sep 30 '21 at 12:28
  • *ZCE is a registry setting that tells Outlook to create a new profile using the SMTP address from Active Directory and to then leverage Autodiscover.* (https://techcommunity.microsoft.com/t5/outlook-global-customer-service/zeroconfigexchange-automating-the-creation-of-an-outlook-profile/ba-p/389691#:~:text=ZCE%20is%20a%20registry%20setting%20that%20tells%20Outlook%20to%20create%20a%20new%20profile%20using%20the%20SMTP%20address%20from%20Active%20Directory%20and%20to%20then%20leverage%20Autodiscover.). – Ivan_Wang Oct 05 '21 at 02:32
  • If it's a local account, ZCE doesn't seem to work except if it has AD attributes(Domain account). If you want to add a secondary mailbox via ZCE, you may need to login to windows with a domain account, create a profile via ZCE which will configure a mailbox in outlook with the current windows credential, and then add your mailbox to this profile and set as the primary(default) mailbox. – Ivan_Wang Oct 05 '21 at 02:33
