How to I import sent email history?
We recently switched our email locations to Office365. When recreating the first new email (they are the same email addresses) on Thunderbird all of the sent email history is gone. I can still see it all on Office365 but not on Thunderbird.
How can I get them to show up on Thunderbird?

Did you back up the mail folders before switching the account? If you can't subscribe to a folder for the new account, open the profile folder and see if there's a subfolder of ImapMail that contains the old account's mail. Help/Troubleshooting Information, click Show in Finder to open the profile in Finder. Look for a file named Sent, with no extension, in a subfolder of ImapMail that is named after the account. Copy the Sent file to Mail/Local Folders (with TB closed), and it should be visible under Local Folders when you restart TB.

Is the Sent or Sent Items folder, whatever it's called, a subscribed folder when you right-click the (IMAP) account in the folder pane, Subscribe, click Refresh? With Hotmail/outlook.com accounts, the 'Place a copy in' box should be unchecked in the Copies & Folders section of Account Settings since sent messages are automatically copied to the Sent folder, so I presume the same for Office365 accounts.
That did not work.
How do I recover the sent email history is the real question.

There was a delayed reaction to the Subscribe process before it finally took, maybe even after rebooting. I can see all the old sent emails again - thanks for the suggestions.
