I'm trying to respond to get help with Tbird. But now there's a problem posting. Suddenly the Mozilla instructions are in Cyrillic and I can't post. I would include a screenshot but although I took a screenshot and I can see it sitting on my desktop, the "Add images...Browse" function does not show it so I can't attach it. Here's the thread (reproduced from Preview pane).

Thanks for your assistance! the error message is: "Thunderbird failed to find the settings for your email account." Here is the info

After providing my existing twc.com email address and other requested information, Thunderbird did a search and came up with "The following settings were found by probing the given server." I used those settings and attempted to create a Tbird-based account. I got this error message: "Thunderbird failed to find the settings for your email account." Which seems odd since Tbird provided those settings by searching the server. What can I do now? I hate to go back to MS Office but I need email and I've spent two days trying to figure this out, including a couple of hours on the phone with Spectrum (they were just as baffled as I am). I still can't use Tbird for email but pls email me at [edited from community support forum] @twc.com and I can access it on my old MS Office computer.

Scary behavior of 'Local Folders': I'm moving an IMAP account from one server to an other. I copy all emails from old server IMAP account to a place described as "Local Folders". I then delete the account connected to the old server. WTF: the the local folders to which I copied the messages are now GONE. My plan was to recreate the account to the new server, then copy messages from LocalFolders to IMAP. But the LocalFolders got deleted along with the IMAP account. This I was doing in a separate profile from my own, as it's for a friend I'm helping with a hosting move.

In my own profile: For more than a decade, I have been maintaining the size of my mailboxes, by moving older messages to LocalFolders. As it happens, for these, I did indeed direct the folder to a separate drive, which also gets backed up offsite. My concern is that 'Local Folders' are portrayed as being INDEPENDENT of IMAP accounts. This is VERY POOR design, to allow a user to delete data they thought was safely stored locally while they recreate a moved or misbehaving account. I have dozens of Local Folders. Five years ago, I abandoned an entire domain name and it's email accounts. I know I still have those emails in my local folders despite having deleted the IMAP accounts from my profile. I fear that the current version, by default, might not be so respectful of my data. Can someone please explain? Where are the links that TIE an IMAP account to Local Folders, and how do I sever that link?

In my case, the source account still exists. I can repeat my steps, but for some other unfortunate users, this may not be the case.

With my Pixel 9a, I installed TB Android mobile. The settings were imported into the phone from my desktop and I went through setup. However, when I tried to sign in I receive an error, Oauth sign in failed. Oauth is currently not supported with this provider. Retry does not work. I use Yahoo Mail on my desktop. My Server is: pop.mail.yahoo.com Security SSL/TLS Port 995 Oauth 2.0 my user name @yahoo.ca These are the settings on my desktop as well. None Next step is to sign in and then I get the error. I tried IMAP, same. Under Oauth 2 there a pull down menu with: Normal password, Encrypted password or Client certificate. I'm not sure what these options are. I tried IMAP and got the same error. I'm hoping that someone can advise me as to how I get past this Oauth 2.0 error and finish installing Thunderbird for Android. Thank you

There are emails after the blanks and I am not sure if any are missing. Also some blank email have been marked as favorite. Even after setting the body display to plain text it is blank. And the metadata containt
