I established a new email address in my existing Thunderbird platform. It only configures an "Inbox" folder and a "Trash" folder. I can not add a "Sent" folder (or "Draft" or "Archives", etc.). I tried deleting the account and re-establishing it, but that did not work. I did notice that emails sent from the new account are being saved in my "Local" account folder's "Sent" folder. I have also gone into "Account Settings" for the new email account to make sure the software was properly configured with where to store sent messages and drafts, but the setting reverst back to the "Local Folders," presumably because there is no "Sent" folder in the proper account. Please Help!!!
