The second option to view another user’s mailbox is to use the option to Open another mailbox. This opens the mailbox in a different window.
1. On the far right-hand side of your Outlook Web where it shows the initials, click on the circle with initials. Then click on “Open another mailbox”.
2. After clicking on Open another mailbox, type in ABC User (the mailbox the user 123 User was granted Full Access to) in the box.
3. Click on ABC User in the list and then click Open.
The ABC User’s mailbox will be opened in a new window. You can verify the mailbox is that of ABC User by looking at the address line. You will see ABCUser@activedirectorypro.com in the address.
