Which Version of EX2007?

As an academic institution, we have access to either version (Standard or
Enterprise) of Exchange 2007. For us, the difference in cost is small
enough that it is not an issue.

We'll have around 1,500 mailboxes and our single server will be fairly beefy
(2 x 2.6GHz QC Xeons, 8GB RAM, Lots os disk space).

Are there factors that would lead us to not use the Enterprise edition?

Thanks!

John

The first two are:
Are you going to cluster?
Are you going to use more than 5 stores?

If either are yes, then Enterprise Edition is what you'll need to
license. Start off with standard and change later. 1500 mailboxes is
only 300 per store so the next question is whether you can allow 300
users to be offline if a store fails and needs to be fixed. Is 300 too
much to manage or would that be ok?

The five store sizes are unlimited in 2007 Standard but keep them down
to a level that won't take you more than 30 to 40 minutes to restore
back from whatever medium you use (plus time to conduct the repair if
one is required).

That boils down to the "What is your RTO and can you achieve it by
using just five stores at the mailbox size you intend to allow?"
