I have tried several times to move the Thunderbird folder from my old PC (Windows 10) to my new PC (Windows 11) by following the instructions in the video. I have several different email accounts. Only the first one has multiple subfolders. The first one never copied anything in the inbox to the new PC but some (but not all) of the subfolders are empty. Sometimes there are no subfolders at all. I noticed that when I copy to Onedrive, it says 822 items are copied. When I copy that file to Roaming on the new computer, it says 245 items are copied. I must be doing something wrong but I cannot figure it out. Please help!

Okay, on the old PC, start TB, click help>more troubleshooting information, scroll down to 'Profiles' in left column and to right is 'aboutprofiles' - click that it it will show you the location of your profile. Copy that folder to new PC and you will have all the account folders.

On new PC, click windows icon in taskbar, at next screen, enter run in command line and a small window will open. In that enter thunderbird.exe -p and press enter. That opens the profile manager. click 'create profile' and browse to and select wherever you copied that folder to. Give it a name for profile manager and continue to TB.
