You can recover a lost server by using the Setup /m:RecoverServer switch in Microsoft Exchange Server 2013. Most of the settings for a computer running Exchange 2013 are stored in Active Directory. The /m:RecoverServer switch rebuilds an Exchange server with the same name by using the settings and other information stored in Active Directory.
Recovering a lost Exchange server is often accomplished by using new hardware. However, you can also use an existing server.
This topic shows you how to recover a lost Exchange 2013 server that isn't a member of a database availability group (DAG). For detailed steps about how to recover a server that was a member of a DAG, see Recover a Database Availability Group Member Server.
