1. We are migrating from Exchange 2007 to 2010. When installing the 2010 server, do the virtual directories for legacy redirection get automatically created? I don't see any documentation of having to manually set these parameters per Microsoft's migration guide, but I don't understand how Exchange 2010 would know to redirect to legacy.mail.com unless it automatically checks 2007's external namespace.
I did find in other (non-Microsoft) documentation that you set these settings manually with the following cmd:
Set-OwaVirtualDirectory -Identity "HO-EX2010-CAHT1\owa (Default Web Site)" -Exchange2003Url https://legacy.exchangeserverpro.net/owa
If this is true, does this need to be set for each service (ActiveSync, OAB)?
2. Our mobile clients were set up manually, as in we do not have an external autodiscover dns entry. So each client is set with server mail.contoso.com with domain\user. Will we experience any problems when we rename the 2010 namespace? I would think it would just continue to connect to that url after we install 2010, and the clients would not know the difference.
We are planning on creating the external dns entry, but I need to know if the initial set up (using server url) will create any problems, as all documentation assumes mobile devices were set up using autodiscovery.
