Open a shared mailbox using Outlook.com
Some departments have access to shared mailboxes or as an individual you may have been given access to someone else's mailbox. You can access these mailboxes using the full version of outlook but sometimes it is easier to use the web based version of outlook.
Step 1 - Open a web browser such as Chrome or Internet explorer.
Step 2 - Navigate to https://outlook.office365.com/
Step 3 - Login if prompted with your school username and password
Step 4 - Click on your picture or initials in the top right corner
Step 5 - Click on "Open another Mailbox"
Step 6 - Enter the email address of the shared mailbox and click ok.
Once you have the mailbox open you can use your browsers bookmark functionality to take you straight back there next time without doing the steps above!
