"Once you decide which platform you wish to access Scalix from, you will be pleasantly surprised, because it is well supported by both Outlook and Evolution PIM clients. For me, this provides so much more than the usual lip service about "openness" and actually backs up its accessibility, thanks in part because Scalix can be used from both Windows and Linux platforms. Bundle its accessibility with the Ajax web access and you have a groupware suite that is both easy to use and does not dictate which browser it works best with. Scalix is also quite extendible (yes, it's a real word), thanks to its flexible plugins and add-ons.
"Best suited for: Larger enterprise environments, small businesses, and non-profits with more comprehensive needs from their groupware suite.
"Zimbra
"Do not let the fact that Zimbra is a Yahoo-owned product these days color your judgment of what to expect from the groupware suite. Without question, my all-time favorite Exchange alternative as it just has a "coolness" factor that is difficult to put into words. Perhaps some of its coolness factor can be best explained away by talking a bit about what sets Zimbra apart from its competition."
