Deleting/emptying entire calendar contents

[apocalypse]

I have a users calendar that contains all doubled (and sometimes tripled) calendar events. I want to delete her entire calendar, and then restore it from a .pst file that I have. I tried using

/opt/zimbra/bin/zmprov sm "user account" emptyfolder /calendar

but that comes back with an error saying "command not found". I am using zimbra version 4.5.2

any suggestions??

ok so,

su zimbra

it's Zmmailbox - Zimbra :: Wiki
Notice the caps:
emptyfolder needs to be emptyFolder or just ef
/calendar I assume your talking about the default cal (which you can't delete) so you need to use /Calendar

zmmailbox -z -m user@domain.com emptyFolder /Calendar

OR

zmmailbox -a admin -p password -m user@domain.com emptyFolder /Calendar

OR

zmmailbox
mbox> adminAuthenticate -u https://server.domain.com:7071 admin@domain.com password
mbox> selectMailbox user@domain.com
mbox user@domain.com> emptyFolder /Calendar
