windows 11, TB MSIX ver 1.0, where are the sent items, draft and deleted files?

I think this is the rough location: Users\username\AppData\Local\packages\MozillaThunderbird.MZLA_h5892qc0xkpca\LocalCache\Roaming\Thunderbird\

ok, how do i get the sent items, deleted items, draft items and spam folders onto my thunderbird side bar ?

More information may help. Did you previously have thunderbird on the pc and recently installed again? If so, it may be that your first install was from thunderbird.net and the second from microsoft. Is your addressbook okay? Try this:: click help>troubleshootinginformation, scroll to 'profile folder' and click 'open folder' and let me know what you see. thank you

One more item: enter %appdata% in windows search bar and press enter key. That should open to the appdata\roaming folder. Is there a Thunderbird folder there? If so, that may be where your data are.
