TB accept my Icloud password, and I'm able to receive and to sent mails, but can not get messages to record in “ sent ” folder of my Icloud account. The “ sent“ folder is listed in my folder panel, but TB give constantly an error message: Your message has been sent, but due to network issues or file access errors, no copy has been placed in your Sent Mail folder (Sent). You can try again or save the message locally, in Local Folders / Sent. Therefore is my “ sent “ folder empty, and not synchronized with my iCloud server. I don't have this problem with my inbox. Thanks for helping me out!
