PostPath Server represents the simplest and most seamless upgrade, both when compared to older version Exchange and even when compared to Exchange 2007. Unlike the Microsoft platform, PostPath runs well on 32- or 64-bit servers, so it will not touch off an avalanche of expensive hardware upgrades. It requires no changes to Active Directory, no changes to the popular Public folder architecture, and it enables companies to leverage cheap and readily available storage technologies for mailboxes, archiving, and high-availability assurance.

Enterprise administrators can download a 12-user copy of PostPath Server, so there's no cost to evaluate the software and determine whether it can serve as a scalable and dynamic replacement or supplement to your Exchange environment.
