I apologize if the answer exists somewhere but I've looked and can't find what is going on. I use Gmail and Thunderbird. I have many folders created for various projects and will drag an email from my inbox into a folder for organization. Sometimes when I do this the email just disappears in Thunderbird. It no longer exists anywhere I can see. Yet if I log into gmail, there it is in the folder it is support to be. Go back to Thunderbird and nada... I've restarted, resynced, resorted and the email just isn't there in Thunderbird or won't be displayed. I've had this happen multiple times and it is frustrating. Can anybody advise what I'm doing to cause this or how to correct it please? Thank you
