iCloud Sync of Calendar items failed

Calendar

After starting up EM Client, I receive a warning message stating

“Synchronisation of the ‘XXX’ folder: The upload of the item ‘YYY’ has failed You can delete the item locally or ignore the error. If you choose to ignore the error now, the system will attempt to upload the item during the next synchronisation. The server responded with the error: Bad Request. The destination folder was iCloud - [email protected]/XXX. Delete item / Ignore” (Translated from German with DeepL.com).

This happens for items that have become due since last EM Client startup. The warning appears for a few weeks now - I have not seen it before. What can I do to fix it?

Since a few days I have the same problem. Is there a solution available?

Could be “you need a new App Password” and then “the account removed and readded”.

Suggest to go to your Apple iCloud account and “revoke and re-generate” a new app password.

Then go to “Menu / Accounts” and remove and re-add your account using the automatic account wizard and use your new generated app password.
