Steps to reproduce: 1. Create a new appointment
2. Right click the appointment and select "Besprechung ansetzen..." (my translation: "Schedule meeting...") 3. Enter a mail address for which the reply address will be different. 4. On the receiving mail account accept the invitation but make sure that the confirmation will be sent with a different sender address than the one you typed in step 3, e.g. due to domain canonicalization like "scooter-attack" instead of "scooterattack" or a mail forwarder. 5. when receiving the confirmation click on "Teilnehmerstatus aktualisieren" (my translation: "Update participant's status" and you will get the message BTW: I tried to reproduce this with KMail, but KMail notices the different address and asks me which one to use for the reply. -- Appointment acceptance mail with wrong sender address poses Yes/No question, but only gives "OK" button https://bugs.launchpad.net/bugs/330601 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
