Hi! I'm a third year computer engineer student which is currently working on my bachelor's thesis. My thesis is a completly comparison of Microsoft Exchange 2003 and Zimbra Network Edition. I know this topic is beginning to get widly used and evaluated, but this is very relevant for our enlisting company that is considering migrating to Zimbra from Exchange 2003. We will also go very in depth in this over 3 months. My projectgroup is currently working on miscellaneous research and for that I could use some help from experienced administrators here at this magnificent forum: 1) We need to simulate a great amount of active users on both Zimbra and Exchange. Is it any scripts for this? A independent stresstest that can run on both mailsolutions is needed. 2) Any topics on this subject that currently haven't been enlighted seriously from a independent view? Maybe something that you system administrators would be interested in knowing but haven't had the time to find it out? I want to emphasize that this project will be totally independent and no part is taken. I hope your feedback will be the same even if you are exchange disciples Thanks in advance. All feedback is appreciated.

You might want to test it against Exchange 2007. Exchange 2003 is an older version.
