zimbra user account changed, calendar entries wrong now
I changed a user's account on the server from say firstname.lastname@example.org to email@example.com
I changed their isync details to the new account.
All their calendar entries now are showing up fine, but they say they were organized by firstname.lastname@example.org, and we cannot edit them!
So how do I change all the appoints created by user to resu?
Or other suggestions, other than spending hours going through each birthday, re-occuring appt, and everything and re-creating them!?
I appreciate any tips and advice. Thanks!
