Exchange 2013 migration, disable SSLOffloading on 2010 CAS servers

Question

We just going through the Exchange 2013 migration from Exchange 2010. I have one or two questions when following the Exchange deployment Assistant. We have HLB where the certificates and we enable SSLoffload on the CAS server. So we don't have public CA's
on our CAS 2010 servers.
So on the documentation it says to run this command, were it will disable SSLOffloading and change to Basic authentication. Will my running outlook 2010 clients start getting certificate errors and  will they work as normal ?
Get-ExchangeServer | Where {($_.AdminDisplayVersion -Like "Version 14*") -And ($_.ServerRole -Like "*ClientAccess*")} | Get-ClientAccessServer | Where {$_.OutlookAnywhereEnabled -Eq $False} | Enable-OutlookAnywhere -ClientAuthenticationMethod
Basic -SSLOffloading $False -ExternalHostName $Exchange2013HostName -IISAuthenticationMethods NTLM, Basic

Answer 1

We have OA enabled on all CAS 2010 servers with NTLM authentication and SSLoffloading box checked. We have also setup our CAS2013 and is running. My question above was that if I ran that command, Will I break anything since all my users
are still on Exchange 2010 mailboxes.
Then as I mentioned, that command will do nothing as OA is already enabled on CAS 10.  It would only make a change if CAS10 had OA disabled. 
Where {$_.OutlookAnywhereEnabled -Eq $False}
Where {$_.OutlookAnywhereEnabled -Eq $False}
