Do you want to log in directly to access your group mailbox?
And what needs do you want to use group mailboxes to achieve?
As Andy David mentioned we cannot log in directly to group mailboxes, but we can use group mailboxes through authorized mailboxes. If you want to log in to the mailbox, you can create a shared mailbox and assign full access permission.
If you want to use a group calendar, you can choose it under Outlook's calendar.
