Steps to recover Failed Exchange Server 2016 Using Recovery Installation

The recovery installation of Exchange server is one of the best action to cope with the failed or corrupted Exchange Server 2016. It provides complete recovery and restoration of the Exchange Server data files, without any database loss issue.
The recovery installation is a stepwise procedure that needs to be performed carefully by the technical user. The various phases involved in the recovery installation of Exchange Server 2016 includes:

Stage 1: Installing New Exchange Server Instance

Firstly, a healthy server needs to be maintained that is used to recover the faulty Exchange server. It can be accomplished by following procedure:

  1. Install a new Windows Server operating system on the system
  2. Set the same drive letters for new instance, which are being used by failed server
  3. Connect the new server instance to the required domain.

Note: All the characteristics of new server instance(server name, server version, drive letters, capacity) should be same as the existing failed server.

Stage 2: Running Recovery Installation Setup

Once the new server instance has been set up manually, it needs to be loaded with the setup files of the existing failed Exchange Server. It can be performed in the following manner:

  1. Copy the setup files from existing server to newly created server instance
  2. In the command prompt, set the path location for setup files of new server
  3. Run the following command on the command prompt
    C:\>setup/mode:recoverserver /IAcceptExchangeServerLicenseTerms

Stage 3: Re-applying the custom configurations

When a recovery install command is run, then it automatically re-installs major configurations stored in the Active Directory of the Exchange Server. However, it contains only server specific files such as virtual directory URL settings, transport information, database location etc. Many important information such as IIS settings, SSL certificates, registry keys are not re-installed by re-installation configuration as these contents are stored locally on the machine. So, user needs to manually configure these files on the new server instance. The SSL certificates being the most crucial component must be re-installed manually by the user. In case of multiple Exchange Server 2016 or 2013, the user can choose export and import option for the same SSL certificates.

Stage 4: Restoring the lost database Volumes

The extent of Exchange server failure may vary according to the situation. If the failure is minimal, then there is no chances of loss of the volumes containing mailbox database. So, the user can easily access the database without any issue.
It may be possible that the database and log files are sustained but are not properly mounted on the server. It can be solved by using command line ESEUtil utility, which allows to scan and recover the damaged and corrupted database and log files efficiently.
