  • Article

In Exchange 2019, like Exchange 2013 etc, you can use a wizard to configure all your External URL's, take note this does not change the Internal URL or the Autodiscover URL, you can change the Autodiscover one as per this article.

Let's go through the wizard that is available from within the Exchange Admin Center (EAC). Launch the EAC and then click Servers -> Virtual directories.

Now click the wrench icon to start the wizard as shown below:
