Outlook - Adding an additional mailbox
Accessing through the NEW Outlook desktop application:-
If permissions are already added the shared mailbox should appear in the new outlook under the Shared with me folder. You can expand it to see if this is the case.
If it is still not appearing, you can try to add it with the following steps:-
right-click on the account name or shared with me folder in the left navigation pane, and then choose Add shared folder or mailbox.

In the Add shared folder or mailbox. dialog box, type the name or email address of the shared mailbox, and then click Add.
If it's still not showing in the Shared with me folder close outlook and reopen
