I had to wipe my hard drive and reinstall windows XP. I backed up my Thunderbird Mail directory created with Thunderbird V1.1, I think. Anyway, after reinstalling windows I installed the latest version of Thunderbird (1.5, I think) and placed all the contents of my backed up MAIL folder into the sub-directory created by T-Bird, called 23hyi8e2.default. That appears to be where it wants to store all the mail. My problem: Thunderbord is NOT recognizing ANY of my transferred mail folders or files! It's like they are not even there! Please help me! I have 250MB of emails important to me to keep and now have no way to access or read them! By the way, Thunderbird never gave me an option to import mail from existing Thunderbird mail files - sort of silly. Can it really be that difficult an option to offer? Never mind. Any help would be appreciated. PLEASE PLEASE PLEASE! Thank You!
