Hello there Mackenzie.krakowski49. We have read your message. We try to help you. You can try to reinstall Thunderbird portable. https://portableapps.com/apps/internet/thunderbird_portable A new install can change the folders status. https://support.mozilla.org/en-US/kb/rebuilding-global-database https://support.mozilla.org/en-US/kb/profiles-where-thunderbird-stores-user-data The emails are stored in a mailbox map on your device. After reset with gloda you can access them again if this option also become blank. The blank screen will disapear after the global base index rebuilding. For portable devices it will be rebuilding the index folder.(if possible) Or reinstall a new version of Thunderbird portable. It will do the same for your portable device. Do not delete sudden folders. Greetings Firefox volunteer.
