Account 1 looks ok. account 6 is definately messy and was added manually hence all the errors. Those details would not be stored in any configuration database. So there is no way that account should be receiving any emails. As it is numbered '6', it would seem you or someone with access to your computer has been trying to add that additional email address or others and removing them 3,4,and 5 have been previously removed.

To help us understand what is going on. Post a images of:

  • Your Folder Pane where you see your folders.
  • Right click on mail account name in Folder Pane and Select 'Settings'. Post image of this 'Account Settings' window.


I wondered if TB was losing track and creating new mail account folders. Please supply this information: In Thunderbird

  • Help > Troubleshooting Information
  • click on 'Show folder' button

a new window opens showing the contents of your Profile folder name, usually called 'xxxxxxx.default' where the x's are letters and numbers.

  • click on 'Mail' folder.

You will see a list of pop mail accounts including 'Local Folders'.

  • Post an image showing contents of 'Mail' folder.
