Dear Madam, Sir, I think I have made a mistake with installing Thunderbird email. I am receiving the emails 2 times and also in the inbox and outbox are shown 2 times. Please see the screenshot attached. Can you please advise how to show normal one time view? Can I just delete the items marked with blue lined area? I want to make sure I will not delete my complete email account. I look forward to receiving your advise on this. Regards, Tineke Verboom
