I Get an error message when thunderbird tries to auto save an email whenim writing it and after i send another telling me it cannot be saved to the sent folder. the problem doesn't solve by retrying or by rebooting in safe mode. I have tried to compact and repair the folders in question. I also don't receive all of the emails I have been sent. Please help as I am a business start up and panicking that i am loosing clients fast. Thank you
