Running Thunderbird 140.6.0esr in Windows 11. This afternoon I found that one of my three accounts no longer shows up in the folder pane, though it still appears normally in the account settings tab. I can still send mail from it, but can't receive any. The other two accounts appear in the folder pane as usual and can send and receive normally.

Any help getting the account back into the folder pane would be appreciated. -- tralfaz

Have been trying to set up some pop3 yahoo mail accounts on a new computer. I have used automatic configuration. I have used manual configuration using the data from my old computer. I have checked the configuration settings on both Yahoo and Thunderbird sites. In all instances Thunderbird verifies the account is valid, but the next window asks for my yahoo username and password. I cannot get passed this stage. I have tried entering my yahoo password and I have also tried the app generated password from Yahoo, all I get is a Yahoo "something went wrong" message. Interestingly I did manage to get one of the accounts to work yesterday, but I must have tried no end of different permutations and I have no idea which one eventually worked.

I received this email after I tried to sign in to my Mozilla account. This is the relevant info from the email:

Your {$providerName} account has been linked to your Mozilla account Mobile Safari on iOS 18.7

I don't know what I did to cause this email to be sent. I wasn't trying to link any other account to my mozilla account.

Account Settings > New Account > Enter passwordless Microsoft account credentials

After this, Thunderbird now prompts me to enter a Password and "Your login", whatever that means. My account does not have a password, but the field is mandatory. What am I supposed to do here, exactly?

Hi, I have googled this and been into the Thunderbird Help section and cannot find an answer. I am having trouble with one of my email accounts, I want to delete it and it and reinstall it. I get to the point in the process where it says to click on Remove Or Remove account but there is no tab or button that is visible to do this. Help here would be greatly appreciated. Regards Mark

I have used Thunderbird for many years with my plusnet email address john@jonela.plus.com. Plusnet no longer manage emails and have migrated to Greenby. Could I transfer my email address to Thunderbird as I do not wish to use Greenby.

Is it possible to change the account name in "Account Settings" without any issues and will this make the mail folders accounts panel on left of the screen show the newly entered name for folders and sub-folders under sent, archive, etc?

The reason I ask is because I think it is ok to initially name the account as whatever I want, as I think the account name is for my own use only, but I'm not sure if changing an existing account name may cause issues or if TB uses the account name for anything.

I have 4 IMAP accounts and 1 local account. I would expect them to be shown as account 1,2,3,4,5, but Thunderbird's troubleshooting info shows them as 1,2,5,7,8. Please see attached picture.

Any idea why? Has something gone wrong? They all seem to be working ok.

When I open my Thunderbird I obtain information: "free link provider, Account is not properly configured".. The problem is I am not able to find a mistake, I have not changed anything in my configuration in recent months. What to do?

Can't access or re-add my existing outlook account to thunderbird 147.0. Tried using my password, an app password. Nothing. Keep seeing the same error over and over again.

I am using version 146.0.1. When I try to change accounts order from "Account Settings" by dragging and dropping the account and restart TB then it is returning to previous order. So I am not able to change the accounts order. Thank you. Ulvi

I have a new Mozilla (FireFox) account and keep getting emails that say I need to confirm it. They include a button to do so but I'm not clicking it unless I get better information from you. Please help. The email swears my account will be deleted if I don't confirm it. What do I do?

After many years of using Thunderbird with an AOL account I changed my password in AOL to increase the security. So I had to install the AOL account again in Thunderbird. I created an app password in AOL and put it in Thunderbird. Everythin fine so far. AOL login window opens automatically. But after login to AOL the message "somthing went wrong" and "try on anther device" pops up. I tried it on several PC's - no way. Other mail clients like Mailspring oder Mailbird did work with the AOL account. What is the problem?

I have 2 hotmail accounts that Thunderbird can access but my wife's one has not since set up.

I have had to set up new email account for my wife because her one she has used for 10 years will end after 6th January 2026 because email service provider is ceasing email business. I have an hotmail address that has worked seamlessly with Thunderbird for 10 years. If it is tried in Thunderbird to access the new account to check for new mail it either states not authorised or not connected. I have tried adjusting settings to be same as mine but not succeed in solving. I am at a loss. Maybe it was easier set up accounts 10 years ago?
