Exchange Server 2010

Our company is in the middle of an upgrade going from Exchange 2003 SP2 to Exchange 2010 SP1. The amount of software required for this caught me off-guard. We had to move from Windows 2003 to Windows 2008 (our domain is already at a 2003 level though, so we’re good there). New hardware required, of course. The Active Directory prep went without a hitch. Now it’s just a matter of moving mailboxes from one server to the other.

I love Exchange, I really do. But I do wish there were some other solid alternatives. We took a hard look at Zimbra, but the cost savings to me just wasn’t worth it, especially considering you have to renew the licensing every year. Does anyone have any opinion one way or the other regarding Zimbra?
