Question : Email Server on a Terminal Server

My customer has five uses and has a single server with Terminal Server.  He now want to install an email server (Exchange or SmarterTools) on it to bring email in-house.   Server resources are not a problem.  Dell really over sold them in the first place.

Has anyone installed Exchange or another Email Server on a Terminal Server?  is it even possible?  yes, I know it is not recommended even if it is possible.

Answer : Email Server on a Terminal Server

Yes, it's possible (as you said, not recommended) - but the Terminal Server itelf will not interfere with the installation of the Exchange Server product line.
