If a user wishes to view their Shared Mailbox via the web, they may do so by following these instructions:
- Sign in to your personal account in Outlook Web App at https://outlook.office365.com.
- In the upper right of the screen your profile image should be listed. Click it and then select “Open another mailbox…”
3. Type in the email address of the other mailbox that you want to open. If you have permission to that mailbox, it should now appear alongside your other folders.
