I am using Thunderbird to download my email from att. I also have it going to my Curve. Since I have update graded my computer (XP to Vista) I receive email on my BB but as soon as I open Thunderbird and download my emails they disappear on my BB. Any thoughts?
In the Thunderbird preferences, do you have the box checked for "leave mail on server"? Otherwise when your computer downloads email into T-Bird it will tell your BlackBerry the email is gone.
