I found a way to clear the duplicates without clearing the whole akonadi database.
Close kmail and open akonadiconsole. In the browser tab, right click on the collection/folder where you have duplicates. Select the "Clear akonadi cache" context menu option. Now open kmail and it will rescan that folder and hopefully the duplicates will be gone. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/883459 Title: KMail duplicates emails To manage notifications about this bug go to: https://bugs.launchpad.net/kdepim/+bug/883459/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
