I have Outlook 2007 on a Windows 10 PC. I want to import all my emails and folders that contain emails, in the same order to my Thunderbird 102. I've already purchased the SysTools PST Convertor program and entered in a fresh PST file that included all my email folders, emails within, contacts, calendars, etc. I then loaded that PST file to the SysTools PST Convertor and created MBOX files (yes, plural as it created a different MBOX file for each folder I had). Now I don't know how to import that to Thunderbird as each time I use the import feature and choose "Outlook", it replies with "PROFILE NOT FOUND". I have no idea how to proceed since I tried to enter these MBOX files (as created by the convertor) into the Local Folders of my Thunderbird profile but just got the folders. Nothing was inside the folders after I restarted Thunderbird. Any suggestions here?? Can't find anything online about this.
