How can I install two instances of Microsoft Mail News?

Features include group calendaring and scheduling, SMTP-based e-mail (HTML based e-mail is available to Java developers), NNTP-based news support, and automatic HTML conversion of all documents by the Domino HTTP task. Notes instant messaging allows you to see your coworkers online and have chat sessions with them. A chat session can be with one person or multiple people (an instant meeting). In its latest incarnation (Notes7) it provides a web services interface. Domino can be a web server for HTML files too; authentication of access to Domino databases or HTML files uses Domino's own user directory and external systems such as Microsoft's Active Directory.
