    Hotmail accounts with multi-copy of emails

    I use Thunderbird (for years) and updated to version 38.5 but may not be the main issue but two (2) hotmail accounts now have multi-copies of the original email. One original and three(3) copies. I how have more than 15K extra emails. Plus,, these now 4 copies have had Thunderbird (maybe?)...
