Hmm, Ok MS fan boy here, I am looking to deploy exchange for some of my 80k customers.
I plan to go MS Exchange 2K7 then someone mentions Zimbra. I think open source for this pup no thanks.
A quick Google on Zimbra vs MS exchange 2007, brings up this document from MS themselves showing where Zimbra is better than Exchange.
Zimbra Email is Better than Exchange 2007… So says Microsoft ..oops
