With Exchange Server 2013 CU9 and Exchange Server 2016 Microsoft has released a new version of the Hybrid Configuration Wizard (HCW). Instead of running the HCW online, it is now a small stand-alone application which is installed on the hybrid server.
Installing and running the Hybrid Configuration Wizard is so easy, initially I didn’t want to write a blog post about it at all. But writing one doesn’t harm, so here we go…
The HCW is only a configuration tool, it configures both Exchange 2013/2016 on-premises as well as Exchange Online. It gathers information regarding the hybrid servers, where to deliver and receive SMTP messages and what certificates are used.
To install the new HCW and reconfigure the hybrid configuration, logon to the Exchange Control Panel and click Hybrid:
To start the HCW and modify the hybrid configuration, click Modify and sign in to Office 365 and click Modify again. This will redirect to a landing page where you can download the new bits:
Click the click here option 🙂
The download will be initiated, and a security warning is shown. You can see that the HCW application is downloaded from an Azure blob.
Click Install to start the installation and in the security warning pop-up click Run to actually install the new HCW application.
When the application is installed the new HCW is automatically started and you’re ready to reconfigure your hybrid configuration.
Click Next to continue. The HCW will automatically detect the servers that are capable of working as a hybrid server. You can opt to not automatically detect and manually select a server as shown in the following figure.
Click Next to continue. In subsequent steps you have to enter credentials for Exchange on-premises and Exchange Online (they will be validated by the HCW), you can select the hybrid domains (all accepted domains in your on-premises Exchange environment will be detected), you can select existing Client Access and Mailbox servers (or Edge Transport servers) for secure email between Exchange on-premises and Exchange online and you have to select on-premises servers that will be used for creating a Send Connector and a Receive Connector.
Select the SSL certificate that’s available (and automatically detected on the hybrid server) and enter the external FQDN of the hybrid server. Please make sure this FQDN matches a name on the SSL certificate. If it doesn’t it won’t work.
When you’ve entered this data the HCW is ready to configure the environment and in the Ready for Update window click Update to start the HCW.
The HCW will run for some time (between 30 and 60 seconds, depending on the size of your environment) and it will show its progress as well.
When the HCW is finished a congratulations window is shown. In this window you can also rate your experience with this new HCW, ranging from zero stars (totally unsatisfied) to five stars (very satisfied) as shown in the following figure.
This is all it takes to run the new Hybrid Configuration Wizard and reconfigure your existing hybrid configuration. And to be honest, when you don’t have an existing hybrid configuration and run this HCW for the first time, it will be same.
