I'd say two things are important, in-house experise (if you're a MS shop, you'll probably feel more comfortable with exchange&co) and TCO. I can hardly claim to be unbiased as we do zimbra integration but we've won quite a few times on the TCO part over xchnge and lotus but the TCO calculation was up to the client. I must say zimbra is fairly low maintainance afterwards, providing it's architecured right. We've done installations for enterprises up to 10k mboxes and consumer up to 300k and there is hardly any serious support issues but your mileage may vary.. And with larger installations getting the TCO is not always easy as some vendors have complicated licensing, you need to take in account the preferred deployment (will it be on VMs, do you already have the infrastructure in place, what about storage - this one is usually the biggest TCO cost, etc). Consider also if you're happy with what you get out-of-the-box or do you need to do some serious integration with other systems, if not provided by vendor, opensource gives you more slack space here.. As the studies go, every vendor will be able to provide you with some but you can guess what they will show =) And in my opinion, all can do the job, what really matters is how you set things up and how much can you afford. I've seen sites with insufficient storage IOPS available and no software can help you there.. Cheers, Jure
