Is there a way to prevent specific devices like home computers from connecting to Outlook Anywhere?  I would like to restrict access to only devices that are members of our corporate domain and are subject to GPO's.

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

No, the entire point of Outlook anywhere is to allow access from... anywhere. All traffic takes place over SSL, so it is secure in that regard - and users still need their AD credentials to log in. If you harden your system and network correctly the security risk is really no different than any other outward facing machine in your environment. In fact it can be less, because they are limited to an HTTPS connection over port 443 only.

An alternative would be VPN or DirectAccess if you truly want to be secure at the device level.
