I set up my new Lenovo desktop (Windows 10), by copying Profile (C:\Users\<account>\AppData\Roaming\Thunderbird\Profiles\<some characters>.default), all’s well now, but had to go through a lot of headaches and I’d like to understand why. What happened is this: I followed standard procedure in copying Profile, tried it several times, but the result was that it would only contain emails from 2020-present, not what I had on Thunderbird on my old desktop, which had separate years for emails going back to the early 2000's, as well as some gmail folders I'd copied over w/MAPI.
What finally got it to work was realizing (with the help of a Cox support tech), that there are TWO locations for the Thunderbird Profiles, the standard one under ...AppData\Roaming (the location you find on TB--"troubleshooting information-- open folder" ), and also under AppData\ Local….THAT was the one that contained ALL my emails, and copying that to the new desktop finally gave me everything I needed.
People on another forum had been trying to help me, and when I reported back that copying over the Local Profile did the trick, I was told that the Local Profile is nothing but a cache, and “Unless you have a very unusual installation, nothing of value is in that Local folder.”
Obviously this does not jibe with the endless hassles I/we had, and our subsequent solution. So I would really like to know: what is the deal with Roaming vs. Local profiles? Was there something unique about my old desktop/setup that made Local the correct profile? (The old desktop was custom-built in 2014, standard Windows setup.) I probably should have asked here first; mea culpa! And THANK YOU in advance for your knowledge/feedback on an unexpectedly baffling process.
