Adding shared mailbox to users outlook profile using powershell

Question

Hello,

Does anyone know how to add a shared mailbox to an outlook profile using Powershell (or any other method with could be used with intune) and set as default?

Cannot add using AutoMapping (has to be a powershell "Add-MailboxPermission ... -AutoMapping $false") as the shared mailbox needs to be the users primary mailbox and must be added direct to outlook for the Dynamics 365 add-in to work.

Many thanks

Mus

You cannot add it automatically, as you will need to present credentials for a user with Full Access permissions, whereas the initial profile configuration needs to be via the shared mailbox address. Perhaps something like Power Automate RPA can do it, or other desktop automation tools.

Answer 2

Hi，

Yes, as michev said.

Setting Shared Mailbox as the primary mailbox still requires the login credentials of the user's mailbox, so you cannot automatically add the Shared Mail Box as the primary mailbox for Outlook through PowerShell.
