Try the following:

Set this setting:

  • 'View' > 'Folders' > 'All'

Then do this:

  • Menu icon > Help > More Troubleshooting Information
  • Under 'Application Basics' - half way is Profile Folders - click on 'Open Folder'

window opens showing contents of your profile name folder

  • Exit Thunderbird now - this is important

Scroll down and delete the following files:

  • folderCache.json
  • folderTree.json
  • virtualFolders.dat
  • session.json
  • xulstore.json

Click on 'Mail' folder

  • delete 'smart mailboxes' folder

(do not worry if it does not exist - it just means you have never used Unified)

Start Thunderbird.

Please Report back on results.

You mentioned in the other question you use a MAC OS.

The instructions above are exactly the same with one minor exception.

  • Menu icon > Help > More Troubleshooting Information
  • Under 'Application Basics' - half way is Profile Folders - click on 'Open Folder'

IF using a MAC then you will find this will say 'Open Finder' instead of 'Open Folder'. Click on 'Open Finder' Then follow same instructions.
