Hi Kevin,

It should work without any problem, and shared mailboxes does not need licenses.

But you can manage inactive mailboxes also using retention policies. Please read here https://support.office.com/en-us/article/Manage-inactive-mailboxes-in-Office-365-296a02bd-ebde-4022-900e-547acf38ddd7

I know this is an old post and I don't know how much of this has changed, but we had an issue where we converted to a shared mailbox but we lost all the archived emails for the mailbox that we converted. Maybe we have to change the retention policy on the shared mailbox? How large can the shared mailbox be? The converted user had an Exchange Online P2 so they had a large archive.
