I'm trying to add new addresss to a personal address book of one of my
users, folder 'Contacts', but it fails with insufficient conditions. From
checking the properties of the contacts fodler, it seems it belongs to me
(the sysadmin) and not to the user. This probably happened during install or
something.
I tried to remove the folder and adding it again, no success.

Any ideas of how to solve it?

Thanks,
Lior
