I am not sure if this is the correct place to ask my question. Apologies if you think it should be somewhere else in Thunderbird Help. My old W10 machine crashed in September. I bought a W11 machine in October. A colleague managed to rescue all my data from the W10 to a HDD. I installed Thunderbird 143.0.1 to the W11 machine. On running the program it found me and my emails. I hoped it would find my wife's emails too. But no luck so far. Both domain names are the same. I've tried adding the details I have for my wife's email as a new account, but the program goes on and on looking with no result, and no end. I have to unplug the power cord to end it. I've followed advice from the help pages to Find and restore my Profile without opening Thunderbird. In the process I've deleted the Profile on the W11 install, and substituted the Profile from the W10 install. It was around 8GB. So I assumed that Local Folders and my wife's details would show. Neither of these things occur. My account is shown together with recent emails. What is happening? How can I get my wife's email account to show? How can I find my archive of emails in Local Folders? Any help gratefully accepted. Thunderbird 101 maybe?
