Yes you need to install components of IIS on a MBX server. Follow the pre-reqs step by step. Also follow the msexchange.org article step by step. You will not install the mailbox role, you will end up installing the Active Mailbox Cluster Role. First you will need to configure the windows cluster. Please follow the article, it will take you the whole way.
