I was able to do this with Sunbird.
It is necessary during a transition from Office Live to Zimbra. The Windows Live Connector allows you a 'IMAPI' connection to the user account through Outlook but there is never a .pst file on the file system. The .pst importer will not work in this situation.
1) Install Sunbird
2) Make a temp calendar
3) Import .csv calendar data to temp
4) Export temp calendar to .ics file
5) Import .ics file into Zimbra account
I'm pretty sure there's a better way to do this but it's all I have for now; It's a little ghetto but it works.
Thanks in advance,
