Restore deleted Microsoft / Office 365 Shared Mailbox

If you delete an Office 365 Shared Mailbox via the Microsoft 365 Admin Center > Users > Deleted Users, it will restore the associated user account in Blocked state with ExRemoved... address, but the Shared Mailbox itself will still be nowhere to be found.

The proper way to restore deleted Shared Mailbox is via PowerShell:

Undo-SoftDeletedMailbox -SoftDeletedObject This email address is being protected from spambots. You need JavaScript enabled to view it.
