SUMMARY *** I try to send a mail with my IMAP account (own-hosted mail server). Upon sending the mail and placing it into the "Sent" folder I get following error from Akonadi: Das Ergebnis kann nicht im Objekt gespeichert werden. [LLCONFLICT] Resource akonadi_maildir_resource_3 tries to modify item 183120 (1652815891176.R135.erik-Aspire-M3-481) (in collection 7) with revision 1; the item was modified elsewhere and has revision 2, aborting STORE. The mail stays in the "Sent" folder marked as unread. I have to mark it as read manually. Deleting and recreating IMAP, SMTP and Identity does not help. Gmail account does not have this issue. akonadictl fsck and vacuum did not help. The error seemed to appear after an update to 5.20.2. *** STEPS TO REPRODUCE 1. Send a Mail with Kmail using IMAP account. 2. OBSERVED RESULT Das Ergebnis kann nicht im Objekt gespeichert werden.

Got into the same problem. Found a workaround. Do in this order as normal user: 1. akonadictl fsck 2. akonadictl vacuum (you can do these both steps twiuce without no harm) 3. Now close kmail 4. akonadictl stop Now the tricky things: 5. Move the folder ¯/.local/share/akonadi/ to somewhere else 6. Start kmail and akonadi 7. akonadictl stop 8. Click in kmail to start akonadi again. 9. Wait some time to let it read all mails. 10. You will see the name of inbox is "inbox". To reset it to your language do the following: as user in terminal: akonadiconsole it will start a GUI. Navigate to "browser" look for "inbox" and delete it. It will be automatically recreated with your language. 11. Ok, last steps: Close kmail and restart it. 12. Now edit all your identities in kmail. You wlll find, that you have to confirm all 3 folders for "sentmal", "drafts" and "template". Important: Athough they are already marked correctly, just set them again. This step is very important! 13. After done this all and exactly in this order as described, the error should be gone! Best Hans 8.
