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
![Exchange 2019 - assign services to an ssl certificate Exchange 2019 - assign services to an ssl certificate](https://everything-powershell.com/wp-content/uploads/2018/12/Autodiscover1.png)
Now you can update the URL using this command:
- Set-ClientAccessService -Identity <ServerName> -AutoDiscoverServiceInternalUri https://autodiscover.domainname.com/Autodiscover/Autodiscover.xml
![Exchange 2019 - assign services to an ssl certificate Exchange 2019 - assign services to an ssl certificate](https://everything-powershell.com/wp-content/uploads/2018/12/Autodiscover2.png)
It completes very quickly, you can then re-run the same command as in step 1 to verify the change:
![Exchange 2019 - assign services to an ssl certificate Exchange 2019 - assign services to an ssl certificate](https://everything-powershell.com/wp-content/uploads/2018/12/autodiscover3.png)
Hope it helps.
