Shared mailbox as primary - or only - account

Modified on Tue, 2 Jul, 2019 at 11:11 AM

There are some scenarios where you want to add a shared mailbox as the primary (or only ) Outlook email account. This means that the user does not need to change the "From" address when sending email. 


  • Remove any existing Outlook profiles/accounts; Control Panel > Mail
  • Launch Outlook, and begin the step-by-step process to add an account
    • type in the email address of the shared mailbox (not your own user email address)
    • when prompted to authenticate (sign in), use your own ("real") email address and password
    • complete the setup

That's it! You can also add another Exchange/Office 365 account if you want, and the shared mailbox will always be the primary mailbox
