Mike, you're the best. That fixed it. I got the Exchange Migration Tool and the Outlook PST Migration Tool from the site you sent. My spamdogs got the two you sent via email. If you'd like to try again, send them to the more friendly
seachnasaigh@gmail.com and I'll likely get them.
For anyone else reading this, the tools worked just great, slick as deerguts on a doorknob as they say round here. I have a test doppelgaenger account with all of the email, calendar, etc. from one of my technicians loaded to a dummy account; we migrated that over to Zimbra and with one small hitch, it worked very nicely. (Hitch: it didn't migrate the Task List ... we're still puzzling over that one since we used a machine with Outlook 2003 installed although not with that user's name).
If you haven't used it before, Microsoft has a tool called exmerge.exe that will turn a user's Exchange mailbox into a .pst file and then import it into another mailbox on Exchange. Pretty slick. It's the tool you use when you're migrating from one Exchange server to another, but it has other uses ... backups are one, and changing a user's Exchange profile name is another. For this migration, it allows me to move a 'safe' copy of a user's mailbox to a neutral location, then import from that location into Zimbra without actually touching the user's existing mailbox. Very handy. Users familiar with Cisco VOIP solutions will recognise it immediately as the tool Cisco uses for voicemail backup and migration. It's free and actually makes getting rid of Exchange a less troublesome and safer process.
Mike, thanks again. We're moving along nicely now and hopefully will purchase a Zimbra Enterprise solution in the next 90 days thanks to your help. Nicely done!
