I wish to transfer my Thunderbird accounts (i.e. I have two different email addresses in one Thunderbird installation) from my 'old' PC to my 'new' laptop.

Historically I have backed up my emails by copying the Thunderbird folder from <user>/AppData/Roaming/Thunderbird and pasting it to my backup disk. This has worked well for more than 6 years. In that time, I've had to recover a couple of times by simply re-installing Thunderbird, establishing it with my main email account (ian_and_maureen@yahoo.co.uk), then replacing the newly established .../Roaming/Thunderbird folder with the archived one, thus recovering all my subfolder data in the Inbox of ian_and_maureen... plus a second email address.

I've tried to do this with the laptop, but I don't fully recover the historical data, all I get is the current Inboxes for the two accounts with no historical data. Can you advise me what I'm doing wrong? If this is the wrong way, what is the correct way? It seems essentially the same action as is described by the guide found at Moving Thunderbird Data to a New Computer | Thunderbird Help (mozilla.org)

My PC is running Windows 10 Version 22H2 (OS Build 19045.4717) with Thunderbird Version 115.13.0 (32-bit). The Laptop is Windows 11 Version 23H2 (OS Build 22631.3958 with Thunderbird Version 115.13.0 (64-bit)
