Hello there Robert tuotte. http://kb.mozillazine.org/Local_Folders http://kb.mozillazine.org/Outbox http://kb.mozillazine.org/Profile_folder_-_Thunderbird#Files_and_folders_in_the_profile http://kb.mozillazine.org/IMAP_folder_cannot_be_deleted Does this map returns without another upcoming problems? Try moving the outbox folder to an untitled newly created folder. Mail back if this fails. The outbox is stuck in the main folder and a solution must be found to prevent this. And solve it. One moment please. Can you send me a picture of the problem please. https://support.mozilla.org/en-US/kb/how-do-i-create-screenshot-my-problem Greetings Firefox Volunteer.
