Bruce,
Pls, follow the kit to the letter. Do not run just Get-OutlookAnywhere but run the exact commands as in the kit to verify settings on each server. As far as I can see the settings are correct now. Both servers listen to external hostname 'enterprise.abswa.com'
The reason you see the error is that you run the Powershell command on the wrong server. You must run the command on the old server because it says -Like "Version 14*". The screenshot clearly show it is run on the SBS 2011 and NOT the Exchange Server 2016
Get-ExchangeServer | Where {($_.AdminDisplayVersion -Like "Version 14*") -And ($_.ServerRole -Like "*ClientAccess*")} | Get-OutlookAnywhere | Format-Table Server, ClientAuthenticationMethod, IISAuthenticationMethods, SSLOffloading, ExternalHostname –Auto
