well i had an update to most of the kmail packages yesterday so i thought i would take another look at organizer and see if it was actually usable yet.

How do i change the default alarm times from the default 15 mins ? i have changed it in the options but it just does not work, it permanently stuck with the default as 15 mins for both To-Do and events.

How do i get kmail to auto-fill from my personal address book ? it does not even see it (yes it is ticked) It only see's recently used address's ?

Autofill works for me. Can you confirm the address book you're using is enabled? (Tick mark next to it in KOrganizer).

yes it is ticked in kontact
