Mailbox moves in Exchange server
Moving Exchange mailboxes from one database to another is required for reasons such as mailbox migration, when a user moves to a different location with a separate Exchange server or when the database disk space runs out. You can move mailboxes from one Exchange database to another from the Exchange admin center (EAC), by using PowerShell cmdlets or by using an Exchange migration tool. The steps listed in this article are relevant for Exchange 2019, 2016, 2013 and 2010.
An Exchange move request is the process of moving a mailbox from one mailbox database to another. The following are the three common types of mailbox moves.
- Local mailbox move: It is a mailbox move that occurs within a single Active Directory forest.
- Cross Forest mailbox move: A mailbox move that occurs between different Active directory forests.
- Remote mailbox move: It is a mailbox move that occurs in a hybrid deployment of on-premises Exchange and Office 365.
