Exchange 2019: Update the Autodiscover Internal URL

In Exchange 2019, to have clients connect without error from the outside, one of the URL's that need to be updated is the Autodiscover record.

The update process is similar/the same as Exchange 2016 and can be done with a single PowerShell command. You can first check what the URL is set to by running this command:

• Get-ClientAccessService | fl

Now you can update the URL using this command:

• Set-ClientAccessService -Identity <ServerName> -AutoDiscoverServiceInternalUri https://autodiscover.domainname.com/Autodiscover/Autodiscover.xml

It completes very quickly, you can then re-run the same command as in step 1 to verify the change:
