-5. If you don't see your internal and external `MAPI/HTTP`, `EWS`, `ActiveSync`, `OAB`, and `AutoDiscover` records in this list, you must add them. Use the following command to add all URLs that are missing. In our example, the URLs that are added are `mail.corp.contoso.com` and `owa.contoso.com`. Make sure that they're replaced by the URLs that are configured in your environment.
+5. If you don't see your internal and external MAPI/HTTP, EWS, ActiveSync, OAB, and Autodiscover records in this list, you must add them using the command below (the example URLs are `mail.corp.contoso.com` and `owa.contoso.com`, but you'd **replace the example URLs with your own**). Ensure that the generic AutoDiscover record for your domain (for example `autodiscover.contoso.com`) is included as well:
 
    ```powershell
-   $x = Get-MgServicePrincipal -Filter "AppId eq '00000002-0000-0ff1-ce00-000000000000'"
-   $x.ServicePrincipalNames += "https://mail.corp.contoso.com/"
-   $x.ServicePrincipalNames += "https://owa.contoso.com/"
-   Update-MgServicePrincipal -ServicePrincipalId $x.Id -ServicePrincipalNames $x.ServicePrincipalNames

+   $x= Get-MsolServicePrincipal -AppPrincipalId 00000002-0000-0ff1-ce00-000000000000

 6. Verify that your new records were added by running the `Get-MgServicePrincipal` command from step 4 again, and validate the output. Compare the list from before to the new list of SPNs. You might also note down the new list for your records. If you're successful, you should see the two new URLs in the list. Going by our example, the list of SPNs now includes the specific URLs `https://mail.corp.contoso.com` and `https://owa.contoso.com`.
