Hi,

 

Whenever trying to update an existing calendar entry on my Mac as well as--by means of synchronising--on my iCloud, I'm receiving an error message on my Mac iCal, reading that it cannot update the entry due to permission issues (error code 403).

 

When having a look into my iCloud calendar and comparing it with the corresponding dates & times in my local iCal, there's quite some significant difference to be observed.

 

Simply deleting the iCloud calender group (along with all its entries) and subsequently re-creating it is no real options, as the next time an existing entry is getting modified, the whole issue starts over again.

 

In the log files I found the following entries:

How would I tackle this one, how can this issue be resolved?

 

Cheers!
