Does any know if it's possible to allow ONLY domain joined machines to use Outlook Anywhere and Exchange 2007.. I understand this may be possible with UAG and endpoint security, but we have no interest in deploying UAG right now. Thanks!

No, there's nothing built in to Exchange that can stop non domain joined computers to connect using Outlook Anywhere.Martina Miskovic

Hi there Exchange server could not verify whether a client machine is domain-joined or not. It can only verify client account. Your understanding would be appreciated. As a walkaround, we may disable Outlook anywhere based on mailbox accounts via cmdlet Set-CASMailbox.

Another walkaround that can block non-domain-joined machine, which is using IIS feature IPv4 Address Restrictions. Refer to: http://technet.microsoft.com/en-us/library/cc730889(WS.10).aspx Fiona Liao TechNet Community Support
