Importing Outlook into Thunderbird

I just installed Thunderbird and used its import tool to import two Pop3 Outlook accounts. It seems to to have worked well. The two accounts are in an Outlook Import folder, which is in the Local Folders. Here are a few questions: 1) Is there a way to activate those imported accounts with their password, server settings etc.? 2) I then created new Thunderbird accounts using the imported accounts' passwords etc. That worked well. It's residing above the Local Folders. Is there a way to move it into the Local Folders? 3) Leaving the new account where it is (above the Local Folder) I was hoping to move every imported sub-folder over using the Outlook's Move tool. It transfers the folder over, but its sub-sub-folders etc. do not transfer over. I hate to have to go into every sub-sub-sub-folder etc. and move every group of emails in it.
