My Apple calendar shows a problem with 'outbox'
Posted by Olivia Rust on 12 May 2017 14:17
[CalDav] Subfolder synchronization of folder "outbox" failed due to the following error: Not Found
This is a server error that started happening recently on Apple servers and applies to eM Client 7.0 and older.
When CalDAV lists the available folders it indeed shows outbox (which is used internally by the calendar for sending invitations) but then also prompts the error because the folder should not be sent or shown through CalDAV to external applications.
We have implemented a workaround which ignores this error in eM Client 7.1
If you encounter no other errors you can just disable all error popups in the meantime.
