If you delete your business mailbox, you will be able to create a new mailbox in its place.
This means that if you had 2/2 mailboxes, after deleting one, you will have 1/2, allowing you to create a new mailbox.
Please note that when deleting a mailbox, its content is deleted as well, and it cannot be restored.
If you need an additional mailbox, it is recommended to consider upgrading your package or purchasing an additional mailbox.
