After reading the article Gregg posted I saw the comments at the bottom and wanted to pass them on from Karen. I am not sure who Karen is but this is a pretty nice comment about their choice and the comments about Microsoft’s service consultants.

I wanted to share that we are in the middle of a migration from Exchange to Lotus Domino. I am amazed of the difference in cost. The Lotus product licenses are so much easier to understand and are significantly cheaper. I would also like to mention for those of you looking at each platform that we always had to hire consultants to do Exchange upgrades but with Domino, its so easy, we were able to do them ourselves. This also was a money saver.
