SP2 for Exchange 2003 will change the 16GB limit to 75GB. This is due in the Autumn (Fall). May affect your thinking.

I currently running Exchange 2000 (I own Exchange 2003 Standard). I am expecting to hit my 16GB limit in 1st quarter next year so I am trying to plan an upgrade to deal with that. The current server is a little old and needs upgrading ideally too. My users are currently less then 90 but expect to double by next year. Options: 1) Exchange cluster Ideally I'd like a lot more redundancy in Exchange as it is so mission critical. So a cluster might be justifiable. I can only cluster Exchange 2003 Enterprise? IMF won't work on a cluster so that is a disadvantage 2) Add a second Exchange server and move some mail boxes to the new server (keep each database below 16GB) Can you add a second Exchange 2003 Standard edition in the same site and use one as a bridgehead for all incoming emails? 3) Upgrade to a single server with Exchange 2003 Enterprise Any suggestions or answers to my Exchange questions would be most helpful.
