Looking to manage user mailboxes in Exchange Online within Office 365? You have two powerful options as your solution: the Microsoft 365 admin center and Windows PowerShell. But hold on, there’s more to it than just deletion.
When you delete a mailbox, the outcome depends on your chosen method. Deleting through the admin center or Exchange Management Shell cmdlets creates what’s known as a “soft-deleted user mailbox.” This mailbox takes up a temporary location in the Azure Active Directory Recycle Bin for under 30 days.
But it’s still a “soft-deleted mailbox” if the Azure Active Directory user account linked to it is soft-deleted. Go beyond that 30-day threshold or hard-delete the associated Azure Active Directory user, and you’ve got a “hard-deleted mailbox” on your hands. In other words, if that soft-deleted mailbox manages to survive the default 30-day retention or you manually delete it, it’s gone for good.
