GoogleApps is not Enterprise-Ready, Part II

Google created the GoogleAppsSync Connector for Outlook to create an Exchange like feel for users who still wanted to use Outlook instead of converting to the GoogleApps interfaces.  The connector installation is fairly straight forward and creates a mail profile for your user.  The last step offers you the option to import existing mail.

DNS Caching and SOA Records
