I need a white paper or technology comparison guide between Exchange 2003 and MDaemon 8.0 from ALT-N. I need to clear up issues regarding compatibility with Windows Active Directory, coexistence with Exchange 5.5 during migration, e-mail free-flow during migration, migration of public folders, mailbox access, security, administration, etc.
Can you point me to any resources?
What is prompting you to stop running a world-class messaging product like Microsoft Exchange? It would seem for nearly 100% of my customers, moving off Exchange Server is simply not an option. I would continue to focus on the upgrade path from Exchange 5.5 to Exchange 2003. E-mail is a mission-critical application that deserves a lot of consideration and attention. Moving away from your already established back-end infrastructure (Exchange) to another alternative is not a light decision.
Maybe you could arrange a meeting between you, Microsoft TAM and the ALT-N vendors to ensure everyone is on the same page in this decision process.
