Adding a shared or delegated (Microsoft 365) account in Outlook Web App (OWA)

A shared mailbox can be used by multiple users to read and send email messages. It can also be used to provide a common calendar, allowing multiple users to schedule and view vacation time, meetings, or work related commitments. Before you can add any shared mailbox, the mailbox's owner must first give you access permission.

You can either add the shared mailbox to your folder list, which allows you to navigate between your mailbox and any shared boxes in the same screen, or you can open the shared mailbox in a separate browser window.

Add the mailbox to your folder list in OWA

  1. In the folder list on the left, right-click your name, then click Add shared folder.
  2. In the "Add shared folder" box that appears, type the email address of the account you wish to add, then click Add.

Open the mailbox in a separate browser window

  1. In the Navigation bar at the top of the window, to the left of the gear icon click your name. In the drop-down that appears, click Open another mailbox....
  2. Enter the full email address of the mailbox you want to open, then click Open. The mailbox will open in a separate Outlook Web App browser window.
