I have a client that currently uses messageware but we would like to remove this requirement. The function that we need to replace and find a solution for using Exchange 2010 is that currently, messageware scans the user's registry that is accessing OWA and tries to locate a entry that identifies the computer as domain joined. This registry setting is distributed to all domain joined workstations using Group Policy. This allows the organization to give different access to company owned computers that are domain joined, and non company owned computers are restricted. Specifically, only the domain joined PCs are allowed to have full access to download attachments. These machines are really not restricted at all. The non-domain joined however are restricted in many ways, caching, attachments and so on... Is there any inherent way I can duplicate this with Exchange 2010 OWA mailbox policies and segmentation? I cannot find anything based on the couple of hours I have spent searching the web...

There isn't that functionality built in to the product which is why MessageWare have it in their product. I cannot think of a feature in Messageware that is available in the native OWA.
The only option you have is the Public/Private computer option on the OWA, but that depends on the end user selecting the correct option. While you can default it to Public, once users realise that changing the option allows them to do what they like, it is useless.

OWA doesn't really make a distinction between internal and external users other than that option. Policies usually apply at a mailbox level and are designed for controlling the user, not the connecting computer.

About the only suggestion I can come up with is to have two separate servers, one for internal traffic, one for external, which have a different configuration on them. That will of course mean additional Exchange licences. I don't think having it in a different web site on the same server would work.

For domain machines that are outside the network, they would have to VPN in to use OWA unrestricted.

Simon.

I disagree that the question wasn't answered - I have fully answered the point that you asked about - simply put, it isn't possible.
