I created a rule that moves my sent emails from account A to account B to have all my sent emails in one single location. However, I notice that then I can't delete or move or edit the emails that are moved by the rule. The only way to do this is to press "Shift+Delete". But I am concerned that long term this will give me issues. Any idea why this happens? Thank you.
