On an Exchange 2007 CAS server, are there any instances when it would not be necessary to have the Microsoft Exchange Service Host service in a started state?

Thank you

Outlook Anywhere:

Microsoft Exchange Service Host:

Configures the RPC virtual directory in Internet Information Services (IIS), and registry data for ValidPorts, NSPI Interface Protocol Sequences, and AllowAnonymous for Outlook Anywhere. This service is dependent upon the Microsoft Exchange Active Directory Topology service.

Installed on Mailbox and CAS servers.

I apologise I missed the "Not" in your question.

If you're not using OA on the CAS server you should be able to stop the service.

Can I ask why you'd want to though, out of interest? What you're trying to achieve?

We are not using OA as we require VPN authentication for remote access.

I don't think it can be stopped. Check below MS article

Which say it is required. "R"

It is not just used for OA. Lot of other features are dependent on this service. So answer is No. VPN will not going to create any problem with this services or vs versa
