How can you restore a deleted mailbox in Exchange?

Restoring a deleted mailbox in Exchange can be effectively accomplished by utilizing the "Connect-Mailbox" cmdlet, provided that the mailbox is within the specified retention period for deletions. When a mailbox is deleted, it does not vanish immediately from the Exchange database; instead, it enters a state where it can still be recovered. This retention period is configured to allow administrators to recover deleted mailboxes before they are permanently removed from the database.

Using the "Connect-Mailbox" cmdlet allows you to link the deleted mailbox back to an existing Active Directory user account or to create a new one if necessary. This cmdlet is crucial for recovery operations because it provides the ability to restore the mailbox functionality while preserving its data, making it a functional and viable method of recovery in Exchange management.

The other options involve methods that are not used for recovering deleted mailboxes: accessing a recycle bin does not apply in Exchange's context as it doesn't have a conventional GUI recycle bin; contacting Microsoft support is unnecessary for standard mailbox recovery procedures and could entail unnecessary delays; and rebooting the server does not contribute to mailbox recovery. These aspects underscore the importance of the cmdlet as the primary means of restoring deleted mailboxes within the defined processes of Exchange management.
