How to Access a Shared Mailbox in OWA
Step 1: After logging in to your individual email via OWA, click on your name in the top-right corner. This will open the Open Other Mailbox window.
Step 2: In the Open Other Mailbox window, type the email address or name of your shared mailbox and then click the Open button. If you typed in your email address/name correctly, the shared mailbox name will appear in the Select Mailbox field.
Step 3: After the shared mailbox name appears in the Select Mailbox field, click the Open button again. You will now be logged into the shared mailbox.
Step 4: To get back to your individual email, go through the same process, except enter your individual email address into the Open Other Mailbox window.
