There are two ways to open a shared mailbox using Outlook Web App. You may want to try both methods and see which works best for you.


  • Add the shared mailbox so it displays under your primary mailbox

    If you want to monitor the email from your primary mailbox and the shared mailbox at the same time, use this method. In addition, after you complete this task, the shared mailbox and its folders are displayed in the left navigation pane each time you open Outlook Web App.

    1. Sign in to your account in Outlook Web App.

    2. Right-click your primary mailbox in the left navigation pane, and then choose Add shared folder. (Your name is on your primary mailbox.)


In the Add shared folder dialog box, type the name or email address of someone who has shared a mailbox with you, and then click Add.The shared mailbox displays in your Folder list in Outlook Web App. You can expand or collapse the shared mailbox folders as you can with your primary mailbox. You also can remove the shared mailbox from your Folder list. To remove it, right-click the shared mailbox, and then click Remove shared folder.

  • Open the shared mailbox in a separate browser window


Use this method if you want to view and manage the email for the shared mailbox in its own browser window.

  1. Sign in to your account in Outlook Web App.
  2. On the Outlook Web App navigation bar, click your name. A list appears.
  3. Click Open another mailbox.
  4. Type the email address of the other mailbox that you want to open and then click Open. Another Outlook Web App session opens in a separate window, allowing access to the other mailbox.



Tip:  If you mistype the email address of the mailbox, the result is "No match was found". Try retyping the email address.
