Save as draft
With Thunderbird 78.3.3 (64-BIT) I get the error message : "Save as draft failed. Your message could not be saved as draft. Send message failed."

Sent messages should not be getting saved as drafts. Open Account Settings, Copies & Folders. What are the current settings for Sent messages and drafts? Your non-English screenshot won't help (me) much here, unfortunately.
I have the default settings.
Why saving the draft fails, I don't know. This may be a temporary problem with the email provider's IMAP server. Unless there's a compelling reason to save drafts in the Drafts folder on the server, I'd rather use the Drafts folder of the Local Folders account.
