Outlook 365 (Windows) - Adding an Additional Mailbox

Issue/Question

How do I add an additional Exchange mailbox in Outlook?

Cause

You may have multiple Exchange mailboxes that you use for work.

Relates To (Environment)

  • Oregon State University
    • Employee
      • Windows
        • Outlook 365

Resolution

  1. Click File in the upper left corner of your Outlook window.
  2. From the Info tab on the top of the sidebar that comes up, click Account Settings and then click Account Settings... in the dropdown menu that appears.

     
  3. From the Account Settings Email tab, click New...

     
  4. Enter in the email address of the additional mailbox and click Connect

     
  5. In the username field, enter your ONID username in the format myONIDusername@oregonstate.edu and click Next

     
  6. Enter in your ONID password on the next screen and click Sign in

     

    Note: If your ONID credentials don't work, contact your IT support team

  7. Click Done when it says Account successfully added

     

    Note: If a browser Windows opens up saying "Complete your outlook setup..." (See below), you may close this window.  This is Microsoft suggesting to install the Outlook mobile app on your mobile device, which is not needed to complete the setup.


     
  8. You will be prompted to restart Outlook. Once you do, the shared mailbox should appear in the Outlook sidebar.
