We are having a problem that reoccurs every few months. Appointments that a
secretary puts in her directors calendar dissapears (from both). We have
tried the cleanviews approach which may fix it for a while (it does not
happen enough to know). The secretary has delegate rights to the other
calendar, unfortunately this is a big problem and they are scheduling
appointments when they are not "free". We need a fix ASAP, that will not
revert the calendars to default settings every day.
