How can I read my old emails from another laptop?

Hello, I have my old Mail file on one computer and no longer have access to the same notes db. I need to move my files to another computer and access them. Also read me, that file doesn't work correct

It is challenging, but doable. Both the new and the old systems must use the same email client program. You then find the location of the files and drop the old email into the proper location on the new pc.

I can document only Thunderbird (TB) but it will serve to give you a starting point.
The TB data is stored at:

• c:\AppData\Roaming\Thunderbird\Profiles\xxx.default\Mail\xxxemailServerDomain\ -here-
