Missing emails

  1. I have just completed transferring Thunderbird from Windows 10 (32 bit) to Windows 11 (64 bit). Running 115 on both machines. The transfer went well but ..... In my profile in the sub folder Mail on the new PC, I ended up with 3 folders - Local Folders, XXXX.com (XXXX is the incoming sever name) and XXXX-1.com. This happened purely by chance with the XXXX-1 file containing all the data and folders off the old PC and the XXXX containing the emails from my internet provider from the time my old PC had died until the transfer.

    If I click on the XXXX file then click on Inbox and open it with Notepad, I can all the new emails. The XXXX file does not contain any of the old emails.

    I have tried everything to open the XXXX file in Thunderbird (incluing renaming and cut/paste) all to no avail. And, of course, the emails were deleted from my internet provider by Thunderbird when they were downloaded!

    Can anyone suggest a way I can retrieve the emails off the XXXX file?

  2. I should add that I did have to rename the XXXX-1 file XXXX in order for the old emails to be read by Thunderbird.
