Some time ago, a user sent a request specifically for a new shared mailbox, that all users should be able to access. When we asked why they didn’t simply use one of the already existing addresses for the use, they said something to the effect that, while there should be no restrictions on accessing the mailbox, only those who wanted to receive email to it should do so. At this point, we started questioning why they had ordered a shared mailbox, rather than a mail group.
