I'm running Thunderbird v. 153.6.0esr (64-bit) on my notebook computer desktop. Yesterday I attempted to re-add an e-mail account to Thunderbird after deleting it to update the settings for that account so that they'd properly align with my ISP's server settings for the account. This originally came about after I changed the account password a couple of times, and found myself unable to send e-mail from Thunderbird. I was, and still am, able to send e-mail from the ISP's webmail app, however.
I installed the update to the Program files folder, which was the default location. Immediately after upgrading, I noticed that the deleted user e-mail account was restored in Thunderbird. The account settings, including server settings, appeared to be correct. Upon closer inspection, I also noticed that the most recent e-mails saved in the inbox and in folders for the two accounts with the same domain name dated back to last year or earlier, even though I received many e-mails addressed to those accounts in Thunderbird since then I can't explain why that happened. Something else rather strange happened: Both the former Thunderbird installation v. 153.6.0esr (64-bit) and the new, upgraded installation v. 160.0 (64-bit) now appear on my Windows taskbar. The first couple of times I did the upgrade to v. 160.0 (64-bit), that version's icon vanished after a few minutes and I was left with the previous v. 153.6.0esr (64-bit). Today, however, I launched Thunderbird from the upgraded Thunderbird.exe app found in the Program folder, which accounts for why the upgraded app's icon still appears on the taskbar. Yet I can still run the previous version just as I could before the upgrade, albeit without the previously deleted user account I sought to restore.
Although what I described may sound like a blessing as I have my choice of versions to choose from right on the taskbar, Moreover, two related Thunderbird apps were restored as well following the upgrade: Lightning and my Address book, although with the same date limitations mentioned above concerning the e-mail files. This very much concerns me, especially because the e-mail files in the upgraded version appear to be outdated by, at first glance, four months to > 1 year. I'm also concerned because I thought the upgrade process would be automatic. This upgrade, however, was anything BUT automatic.
I find myself getting busier with work these days, and as we're nearing the holiday season. I simply don't have time to troubleshoot this now. I can use Thunderbird on my mobile phone without a problem. I don't wish to use it on the ISP's webmail app as it would simply be too inconvenient in the long run. Please help if you can, at least by offering or providing an explanation of why the above anomalies happened. Also note that I have a recent full image backup of my hard disk. I'll be glad to make screenshot images of this latest configuration available to you upon request.
I have one more, but related, request. If you know of a way I can restore the deleted user account I referred to above to my previous version of Thunderbird, 153.6.0esr (64-bit), let me know what that is and I'll gladly delete the new v. 160 I upgraded to. I'd like to be able to upgrade to that version smoothly and without the inconsistencies I encountered with this upgrade, but I recognize the need to do it without losing at least a year's worth of e-mail data, as described above.
