I tried to use the button kontact/kmail shows me (record, move to trash, delegate, forward, check my calender) to add a calender event of a received email invitation (attached .ics file). Clicking record does NOT add anything to my calender and the email gets deleted. It is completely deleted, not moved to trash or some other place so I cannot recover it. The email contained invitations for two events so clicking record on one event already deletes the email so you can't add the second event. I had to request the invitation again and made a copy to try again, same problem. I think kontact should have never deleted the email, it might contain other important stuff and you might still need the invitation email for other purposes. And of course I would expect it to really add the calender event and ask which calender I would like to use. opening the files and adding them to my calender of choice with korganizer worked as expected. Reproducible: Always I didn't know whether to add this under kontact or kmail, please move it to kmail if
This bug has only been reported for versions before 4.14, which have been unsupported for at least two years now. Can anyone tell if this bug still present? If noone confirms this bug for a Framework-based version of kontact (version 5.0 or later, as part of KDE Applications 15.08 or later), it gets closed in about three months.
Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.0 aka 15.08), please open a new one unless it already exists. Thank you for all your input.
