Help me : Autodiscover service in Exchange 2007/2010 for internal network or non - domain joined client.

Hi all,

My lab has 2 stand-alone PCs installed 2 different Exchange versions

PC1: Exchange 2007

PC2: Exchange 2010

To configure  Autodiscover for Exchange 2010/2007 in internal network or non-domained joined.

1. From PC1 (same as PC2), go to DNS , create SRV record with parameters:

- Service: _autodiscover

- Port: 443

- Protocol: _tcp

- Host: FQDN of Exchange server (I just want to test for internal network)

2. Test web service :

C:\>Test-OutlookWebServices -identity:johnc@alpineskihouse.com | ft * -AutoSize -Wrap

successfully.

But I also read some document and know that we should configure Client Acess, OWA,... like as:

##Enable Outlook Anywhere for your CAS server 

Enable-OutlookAnywhere EXCAS -InternalHostname mail.contoso.com -ClientAuthenticationMethod Basic -SSLOffloading:$False 

##Configure the SCP for internal Outlook clients 
Set-ClientAccessServer EXCAS –AutoDiscoverServiceInternalUri https://mail.contoso.com/Autodiscover/Autodiscover.xml 

##Configure the offline address book settings 
Set-OabVirtualDirectory EXCAS\OAB* -InternalUrl https://mail.contoso.com/OAB -InternalUrl https://mail.contoso.com/OAB 

##Configure the web services which include OOF and free/busy information 
Set-WebServicesVirtualDirectory EXCAS\EWS* -InternalUrl https://mail.contoso.com/EWS/Exchange.asmx -InternalUrl https://mail.contoso.com/EWS/Exchange.asmx -BasicAuthentication:$True-WindowsAuthentication:$True 

##Configure the unified messaging settings 
Set-UMVirtualDirectory EXCAS\Unified* -InternalUrl https://mail.contoso.com/UnifiedMessaging/Service.asmx -InternalUrl https://mail.contoso.com/UnifiedMessaging/Service.asmx -BasicAuthentication:$True -WindowAuthentication:$True 

Question 1: 

So, do we need to follow all comments as above - are all steps enough (because I heard that we need to test autoconfiguration in Outlook)?

Or just we only configure as step 1,2

Question 2:

All steps are suitable for both of Exchange version (2k7, 2k10)

Question 3:

all Exchange servers are stand-alone , so if another topologys , all steps are OK ?

Please give me your ideas ? Thanks.

I  friendly want to emphasize that I only test with non-domain client
