Has Anyone Used Evolution in an Enterprise?

Sikmaz asks: "We have a few Solaris clients that our graphics department uses, they are now requesting access to our exchange server from those systems. They currently use IMAP to connect using Mozilla Mail but they want to view calendars and tasks. I know that Evolution works on Solaris so I am investigating using it in this instance and in a few other areas where we run various flavors of Unix/Linux. Does anyone have any experience in using the Evolution Connector in an Enterprise environment? Was it stable and how well did it scale? Since it pretty much runs on OWA should I just get another Front-end server to run OWA just for this purpose or is it stable enough to run on one of our current OWA servers? How well does it mimic all of Outlooks features, does it do all of the Calendaring/group collaboration features?"
