Install the Edge Transport server role


Estimated time to complete: 40 minutes

The Edge Transport server role performs anti-spam filtering and applies messaging and security policies to messages in transport. The Edge Transport server role can't coexist on the same computer with any other Exchange server role. You should deploy the Edge Transport server role in the perimeter network and outside the secure Active Directory forest.

After you install Exchange on a server, you must not change the server name. Renaming a server after you have installed an Exchange server role is not supported.

How do I do this?

  1. Log on to the computer where you want to install Exchange 2016.

  2. Navigate to the network location of the Exchange 2016 installation files.

  3. Start Exchange 2016 Setup by double-clicking Setup.exe


    If you have User Access Control (UAC) enabled, you need to right-click Setup.exe and select Run as administrator.

  4. On the Check for Updates? page, choose whether you want Setup to connect to the Internet and download product and security updates for Exchange 2016. If you select Connect to the Internet and check for updates, Setup will download updates and apply them prior to continuing. If you select Don't check for updates right now, you can download and install updates manually later. We recommend that you download and install updates now. Click Next to continue.

  5. The Introduction page begins the process of installing Exchange into your organization. It will guide you through the installation. Several links to helpful deployment content are listed. We recommend that you visit these links prior to continuing setup. Click Next to continue.

  6. On the License Agreement page, review the software license terms. If you agree to the terms, select I accept the terms in the license agreement, and then click Next.

  7. On the Recommended settings page, select whether you want to use the recommended settings. If you select Use recommended settings, Exchange will automatically send error reports and information about your computer hardware and how you use Exchange to Microsoft. If you select Don't use recommended settings, these settings remain disabled but you can enable them at any time after Setup completes. For more information about these settings and how information sent to Microsoft is used, click ?.

  8. On the Server Role Selection page, select Edge Transport. Remember that you can't add the Mailbox server role to a computer that has the Edge Transport role installed. The management tools are installed automatically if you install either server role.

    Select Automatically install Windows Server roles and features that are required to install Exchange Server to have the Setup wizard install required Windows prerequisites. You may need to reboot the computer to complete the installation of some Windows features. If you don't select this option, you need to install the Windows features manually.


    This option installs only the Windows features required by Exchange. You need to manually install other prerequisites manually. For more information, see Exchange 2016 prerequisites.

    Click Next to continue.

  9. On the Installation Space and Location page, either accept the default installation location or click Browse to choose a new location. Make sure that you have enough disk space available in the location where you want to install Exchange. Click Next to continue.

  10. On the Readiness Checks page, view the status to determine if the organization and server role prerequisite checks completed successfully. If they haven't completed successfully, you need to resolve any reported errors before you can install Exchange 2016. You don't need to exit Setup when resolving some of the prerequisite errors. After resolving a reported error, click back and then click Next to run the prerequisite check again. Be sure to also review any warnings that are reported. If all readiness checks have completed successfully, click Next to install Exchange 2016.

  11. On the Completion page, click Finish.

  12. Restart the computer after Exchange 2016 has completed.

How do I know this worked?

Run Get-ExchangeServer

To verify that Exchange 2016 installed successfully, run the Get-ExchangeServer cmdlet in the Exchange Management Shell. A list is displayed of all Exchange 2016 server roles that are installed on the specified server when this cmdlet is run.

For detailed syntax and parameter information, see Get-ExchangeServer.

Review the setup log file

You can also learn more about the installation and configuration of Exchange 2016 by reviewing the setup log file created during the setup process.

During installation, Exchange Setup logs events in the Application log of Event Viewer on computers that are running Windows Server 2012 or later. Review the Application log, and make sure there are no warning or error messages related to Exchange setup. These log files contain a history of each action that the system takes during Exchange 2016 setup and any errors that may have occurred. By default, the logging method is set to Verbose. Information is available for each installed server role.

You can find the setup log file at <system drive>\ExchangeSetupLogs\ExchangeSetup.log. The <system drive> variable represents the root directory of the drive where the operating system is installed.

The setup log file tracks the progress of every task that is performed during the Exchange 2016 installation and configuration. The file contains information about the status of the prerequisite and system readiness checks that are performed before installation starts, the application installation progress, and the configuration changes that are made to the system. Check this log file to verify that the server roles were installed as expected.

We recommend that you start your review of the setup log file by searching for any errors. If you find an entry that indicates that an error occurred, read the associated text to determine the cause of the error.
