Overview

This topic provides the steps for installing the necessary Windows Server operating system prerequisites for Exchange Server 2016 and Exchange Server 2019 Mailbox servers and Edge Transport servers, and also the Windows prerequisites for installing the Exchange Management Tools on Windows client computers.

After you've prepared your environment for Exchange Server, use the Microsoft Exchange Server Deployment Assistant for the next steps in your actual deployment. For information on hybrid deployments, see Exchange Server Hybrid Deployments.

To actually install Exchange Server, see Deploy new installations of Exchange.

What do you need to know before you begin?

This section provides comprehensive recommendations and the most up-to-date information about the components necessary for Exchange Server. These components are essential prerequisites for the proper functioning of Exchange Server.

Windows Server prerequisites for Exchange 2019

The requirements to install Exchange 2019 on supported Operating Systems (OS) are described in the following sections. We recommend either of the following methods to install the Windows prerequisites for Exchange 2019:

  • Use the /InstallWindowsComponents switch in unattended Setup mode.

When you use one of these options, you don't need to restart the computer after the Windows components have been added.

Exchange 2019 preparing Active Directory

You can use any member of the Active Directory domain to prepare Active Directory for Exchange 2019. To prepare Active Directory using the graphical user interface (GUI), you need to install the Exchange Management Tools role.

  1. The computer which is used to prepare the Active Directory requires the following software:

      If you're using unattended Setup from the command line to prepare Active Directory, this package isn't required. For an overview of the latest supported versions and more information, please refer to Prepare Active Directory and domains.

      The system requirements for the Visual C++ Redistributable package do not explicitly mention support for the latest Windows Server versions. However, the redistributable package is safe to install on these versions of Windows.
