i just found a little tool called "reminderfox", which is an addon-on to Thunderbird and/or Firefox. It let's remind you with popups to calendar entries in Zimbra.
What's working and not:
+ I can subscribe to a ZIMBRA-calendar with making an entry in the settingsfield:
Using the username & password of the user.
==> Everything seems to be okay...
+ I can ADD a NEW entry in 'reminderfox' which will (and that's surprises me) synchronize in realtime to Zimbra.
- BUT: I cannot see calendar entries which are made with the ZIMBRA-UI.
How can that be ? I can PUT entries, but cannot fetch entries to / from Zimbra.
Anybody any idea, how to fix this ?!
Because 'reminderfox' will be a really nice tool, to compensate for the missing reminder functionality in Zimbra, which is, that's putting it mildly, not really state of the art.
It could be an important and convenient enhancement for users which are using Zimbra in combination with Thunderbird.
I hope, that there will be some folks out there which have the same problems as i have to implement Zimbra without having the basic function of reminding people to their appointments, WITHOUT switching their windows to the browsers' one...aka overlapping the reminder-popup.
