Installed latest version of TB and want to migrate account settings and messages from Postbox to Thunderbird. I used the TB import tool and selected the active Postbox profile to import. All three accounts were imported. All the emails in one account were imported. In the case of the other two accounts, one of which is active and one is inactive, TB only imported the message headers only, not the contents. I then found a migration app from a software company that was supposedly designed specifically to migrate Postbox accounts and messages to TB. When I ran the app, I got the exact same results as when I did it manually. Any ideas on why the message content is missing on all emails in the two other accounts? The account settings are unchanged from Postbox. Thanks!
