Thanks to all on the list for the suggestions. As you may notice by my email address, I don't work corporate. I'm in Education, so the 2,000 users comes from our student population (it's a small school). I have our Administration (less than 100 users) on it and it's a more of a chore to support than the over 2,000 users on the Unix system. The costs and backup times are real to us, but my boss is looking for third party (not me basically) documents on reasons not to migrate the rest of the users to Exchange. I have looked at OpenExchange and the like, but I need more proof AGAINST Exchange than I do FOR Unix systems.

He recovered, but it required inside knowledge. - Message store is kept in only one file, that cannot be backed up online. You hae to stop service for backups.

- i can not think of one week that the server didn't die at least once, and we only had 150 people on the network (not 2000 like you). - the total mailbox (i.e. everyone's mailboxes combined) size is restricted depending on what version of exchange you are using (standard, professional, etc). i.e. if you want bigger, you have to upgrade! (now where have i heard that before?) - you have to have a license to run exchange on the server. - you need a client access license for every computer that is going to
connect to the server - if you want web-based access to your e-mail, that's another set of licenses
