For Exchange Server Recovery you can use these following steps:-

• You can reset the computer account for the lost server.
• You can install the proper operating system and name the new server with the same name as the lost server. Recovery won't succeed if the server on which recovery is being performed doesn't have the same name as the lost server.
• Join the server to the same domain as the lost server.
• Install the necessary prerequisites and operating system components.
• Log on to the server being recovered and open a command prompt.
• Navigate to the Exchange 2013 installation files, and run the following command: Setup /m:RecoverServer
• After Setup has completed, but before the recovered server is put into production, reconfigure any custom settings that were previously present on the server.

If these steps are not beneficial for you then you can install Stellar Phoenix Exchange Server Recovery Software that is very much helpful in recovering all data from Exchange database and provides full support for all Exchange Server versions.
