Exchange 2000 vs 5.5

Locked

I am in the planning stages for a move from a legacy-based email system to Exchange. Our timeline is Q1 2001 for roll out, and isn’t flexible. I have heard the rumors of August 2000 release for Exchange 2000, but I generally don’t adopt a MS product until SR-1.

My question is, would Exchange 2000 or 5.5 make sense? We don’t want to have to upgrade in the next 2 years, but we can not have an unreliable mail server.

I will give full points to the best answer and partials to those with good issues.

If you have NT 4.0, and are sticking with it for two years, then it would make sense to install Exchange 5.5. However, if you are migrating or installing Windows 2000, then I would consider going for Exchange 2000.
Judging by your sensible idea ofwaiting for SR-1, I suspect that you have NT 4.0. So you will need the Enterprise edition of NT 4, and its recommended to have Exchange on its own Member Server rather than a Domain Controller. If your specing a new machine then go for Twin or quadprocessor and 512 MB RAM minimum. You will not get the benefits of Exchange 2000 without Windows 2000.

Whether you are staying at NT 4 or 2000 Exchange 5.5 will be around for some time to come. It also will integrate nicely with your Active Directory.
