Version: 4.2.2 (using KDE 4.2.2) OS: Linux Installed from: Ubuntu Packages When I delete an event with attendees, while groupware communication is off, an email is sent to the attendees without confirmation. If I however activate groupware communication, I get a question weather to notify the attendees about the cancellation.
I'm experiencing the same bug with Korganizer 4.7.4 : even if I un-checked "Groupware communication", korganizer still sends mails to organizers/attendees, and its really annoying. When "groupware communication" is off, any mail feature related to Korganizer should be disabled.
