Up until a few weeks ago, I used Thunderbird with my Google Apps email. I used the Gmail app on my phone and often accessed my email through a browser (primarily for "filing" messages after I've dealt with them). I've never seen the behavior that Donald is seeing. I have adjusted the folders and in most cases, it messed things up. I vaguely recall one issue - no longer the case, by the way - where Thunderbird had a folder called "Sent messages" while Gmail called it "Sent mail" (currently it's just "Sent") and while messages didn't get lost, this "Sent messages" folder only existed inside T-Bird so at home, using my web browser, I couldn't see messages that I sent. IMO, that was a T-Bird misconfiguration that's since been fixed.
