Failed to upload item "aaa" when dismissing all alerts of a reminder window

Everytime I dismiss an iCloud task alert there is this error (see screenshot), for every reminder that a dismissed in the alert box. iCloud synchronization itself works without a problem (calender, tasks, contacts). Also I can’t see a problem in the log. And I didn’t change anything on any other device connected to iCloud in the meantime.

Why is this message everytime?

I’m using emClient 6.0.21040.0.

Hi, can you please try to update your client to this release, and check if the issue persists?
If it does, please right click your tasks folder in eM Client and select Properties > Repair and click on the “Repair” button.

Hope this helps,

Hi Paul

Sorry for the delay, more important issues prevented me from answering.

I updated the client and repaired.

I have updated to 6.0.21372.0 in the meantime, but the problem persists.


Hi again Jan, can you please navigate to Tools > Settings > Advanced and enable CalDAV/CardDAV logging for the problematic account?

  1. Save the settings
  2. Restart the application
  3. Replicate the issue
    Once the issue reoccurs, please go back to the advanced setting window and submit the logging data to my email, [email protected] with a reference link to this forum topic by clicking on the “Send logs” button.

Thank you,
