I am using Outlook 2003. We use the calendar and contacts also. I don't find very many people that love Outlook but it's files are universally recognized. I searched for that mbs ext and found it is for Opera mail. I found a utility for that with a trial mode. It has a plain text option so I set that and so far it has worked on two of my files so far. So all that is left is translate the juno files. Maybe a utility for that?
