Are you sure you wanted to post this question in the Excel Zone?

See if this helps:


Essentially the difference in 2003 is the number and maximum size of the stores. In 2007 it's just the number of stores.
In any Standard Edition you can't cluster.

And if you want to see something about the features available accross the board you can see:
Here's a Microsoft KB article that shows the differences between Standard and Enterprise Exchange.

In a nutshell here's what it says:

Exchange Server 2003 Standard Edition
Exchange 2003 Standard Edition is designed to meet the messaging and collaboration requirements of small and medium corporations and for specific messaging server roles or branch offices. " One storage group can be created on a server
" One mailbox store database and one public folder store database that can be accessed by using MAPI and Outlook Web Access
" Up to four more public folder store databases that are accessible only programmatically
" Maximum 16-gigabyte (GB) database limit per database (75 GB with Microsoft Exchange Server 2003 Service Pack 2)
" Exchange clustering is not supported
" X.400 connector is not included

Exchange Server 2003 Enterprise Edition
Exchange 2003 Enterprise Edition is designed for large enterprise corporations. With Exchange 2003 Enterprise Edition, you can create multiple storage groups and multiple databases. Exchange 2003 Enterprise Edition provides an unlimited message store that removes the constraints on how much data a single server can manage." Four storage groups

Must be a good link.  That's the third time it's been posted :-)

Yeah, it's pretty high up the list if you do a Google search for it. There are others out there if you Google but the ones that you've been pointed at are all you need really.
