On latest Thunderbird, the inbox shows a number of unread emails but some of the emails didn't come into the inbox. When I verify thru my webmail, I can find the "missing" emails. Went thru most of the THunderbird settings to try to find if anything was filtering or junking them but nothing should have left them out. Its not a huge issue to verify it over webmail but just wondering if this is a known bug or user/network error. Hitting "Get messages" doesn't retrieve these old emails that didnt come in, even though they show up in my webmail.
