countach said:Ouch. If you can save your mail boxes into PST format, then google for PST to mbox convert, you'll find some ways forward. Then repent and never store your mail in a proprietary MS format again!
I am not sure that a proprietary mbox format is any better in the long run. I have bounced between Mac and Windows for years and really wish I could move mail back and forth to suit the current system of choice. Though with Spotlight I am tempted to convert all mail to text files and be done with it.
