Problem: Icloud Calendar Moving Events from one calender to another

Icloud Calendar Moving Events from one(Local) calender to another (Icloud)
error message say forbidden

It works if the Event was created on an IOs device but not with Other ICS files imported

Hi, can you make a screenshot of the error message you’re seeing?
What version of eM client are you using?

If you move a calendar event from a different account (maybe gmail, or any other account), is it possible to move the event?
What if you open the details of the event and switch the calendar? Does the same message popup?

Also could you go to Tools > Settings > Advanced and turn on CalDav logging for the problematic account, save the settings and restart the application, try to right click your icloud calendar folder and select properties > Repair and click on the repair button.

Then try to please replicate the issue (move the event) and if the error pops up, go back to the advanced settings window and click on “Send Logs”, please send them to my email ( and please add a reference link to this forum topic.

Thank you,
