maybe once per day, sometimes more or less, i get the 'login to server failed' with the option to retry. the retry always works, usually the first time, but sometimes requires another retry. this apparently started happening after an update, because it never happened before a few months ago. i figured another update would fix the issue, but nothing has changed yet. j

is there a retry setting somewhere that i'm missing?

i have pop3 account and unchecked leave on server - but greyed and checked out is a 'leave for a maximum' which i have as 1 day, there doesnt seem to be an option to uncheck this? I dont want them on the server which is why i chose pop account. yet when i open web account, the emails already downloaded using the pop account are still there even thoug they were downloaded days ago. Why is this and how do stop this? is there a 'leave copy on server' box to uncheck that I am missing? i want to use pop to remove from server and just use locally but its not doing what i thought it would, which is remove from setver. Also it keeps repeating downloading from years ago so I was hoping that when the server synced it would stop downloading the ones it has already (mulitple times) I made an imap account to try to sort emails that way but it also shows old emails still on server. Should i delet this imap account as I already have a pop account running? Very confused. Help figuring out what to do appreciated.

When you connect a mailbox in the Thunderbird program, the server connection parameters are automatically loaded. There is an error in these parameters - instead of the imap.yandex.ru and smtp.yandex.ru are being imap.beget.com and smtp.beget.com . What do I need to do to automatically download the correct settings when the mailbox is connected?

my email is not synced to my phone or my other computer on my new Win11 computer . Yahoo is but not Thunderbird . I have to mark as read or delete messages that have been read on other devices when I get to this Win 11 machine . Thanks ! Ken

Hi,

I've read some of the support topics about the super narrow scroll bars in Thunderbird. I did go to: https://www.reddit.com/r/Thunderbird/comments/1fz9f5j/comment/lr02b8z/

which was suggested. I did the fix, which helped one problem (the super narrow scroll bar size), but there are no up & down arrows on the scroll bar. This was a really helpful feature. Is there any way to get the arrows back? The screenshot shows how TB looks in Windows 10. That's exactly what I want the scroll bars to look like.

I'm using Thunderbird 140.4.0esr (64-bit) on Linux (Zorin Pro 17) on a Lenovo Thinkpad X1 Carbon.

Thanks a lot, DD

T-Bird one Yahoo of six accts, repetitive “ENTER CREDENTIALS” My T-bird release: 144.0.1 (64-bit) Desktop: WIN 11 Pro – with all updates

= =

For the last few days, I have not been able to obtain emails on my desktop T-Bird for one of my six Yahoo accounts. And, I cannot send any emails from the account

= =

BUT, I can access the target Yahoo email account via my desktop Firefox, via Android T-Bird and via Android/Firefox. And all incoming and outgoing emails are present. Stymied, I changed the Yahoo acct password. After the change, these three work domains perfectly as before. And again, all incoming and outgoing emails are present.

= = =

BUT, the repetitive error with my desktop T-Bird for the one Yahoo account persists. The POP-UP provides a long string in the URL window and the only text shows: “Edge: Too Many Requests” >>>>>>>> I’m not using EDGE [Yahoo must use EDGE for the login error POP-UP] The window in the bottom Task Bar displays: “Enter credentials” [repetitively – ad nauseum].

= =

This is the copy of the Yahoo URL in the POP-UP: https://login.yahoo.com/?src=thunderbird&client_id=dj0yJmk9NUtCTWFMNVpTaVJmJmQ9WVdrOVJ6UjVTa2xJTXpRbWNHbzlNQS0tJnM9Y29uc3VtZXJzZWNyZXQmeD0yYw--&crumb=mdAGY49jGd8&login_hint=name_of_email_acct%40yahoo.com&redirect_uri=http%3A%2F%2Flocalhost&pspid=954010027&activity=thunderbird-imap&done=https%3A%2F%2Fapi.login.yahoo.com%2Foauth2%2Fauthorize%3F.scrumb%3D0%26client_id%3Ddj0yJmk9NUtCTWFMNVpTaVJmJmQ9WVdrOVJ6UjVTa2xJTXpRbWNHbzlNQS0tJnM9Y29uc3VtZXJzZWNyZXQmeD0yYw--%26redirect_uri%3Dhttp%253A%252F%252Flocalhost%26response_type%3Dcode%26scope%3Dmail-w I changed my email account name in the display above to: name_of_email_acct; all else is verbatim.

= =

For clarity all six accounts work without encountering "Enter credentials" on the desktop via Firefox, my android via T-Bird app, my android via Firefox. Five of the six work on my desktop T-bird.

= =

I did not add any extensions in the last week. I did disable all extensions (and restarted) with no change in behavior. I put a 25 cent piece on the keyboard to appease the computer gods – no change.

= =

Yup: cleared cache and cookies. Deleted password from desktop T-Bird repository, but the new one is not recorded. Changed authentication from OAuth2 to Normal and back again- no change

= =

Yes, I waited multiple hours to try again, with no luck.

= =

Thoughts ????

You have already solved my problem. I followed the menu to my accounts and while it showed me how to see the passwords it did not tell me how to edit them which was when I searched how to edit passwords Thunderbird explained how I had to hold control and click on the account and as shown the menu appeared. After that I hit the thumbs up and then was sent to this page after I signed into my mozzilla account and asked me ask a question but as I said you have already solved my problem. Thanks for the help

When made to change my password by my email provider, instead of deleting my old password in Thunderbird I accidentally deleted the entire saved login (Thunderbird > Settings > Privacy&Security > Passwords > Saved Passwords > then deleted the entire saved login instead of only deleting the old password). When I tried adding my account login back to Thunderbird using “+ New Account”, it gives me an error message that my incoming server already exists. I'm trying to get my old saved login back without doing any more harm. I can still get into Thunderbird but it won't connect to the server (my login credentials now fail). I can still see and read my old emails but it won't retrieve any new emails. Is there a way to get my old login credentials back or re-enter them into Thunderbird? If not, are there files and folders I can copy from my old saved Thunderbird Profile directory into my active Profile directory to be able to login to my account again while keeping my local folders? I saved a lot of my email to my local folders, so I'm hesitant to overwrite my Mail folder (and even my ImapMail folder) for fear of losing my existing folders, especially my local folders.

Something changed. I’ve tried to set up my old AOL email account multiple times using different default browsers, and the setup typically fails. Using Edge, I get “Edge: Too Many Requests” . Using Firefox, I get “Waiting for authorization in login popup…” and then the old rotating arrow. After about a minute delay, the Account Hub reports “Authentication error.” The Thunderbird Account Hub reports the outgoing server settings test good. I’ve changed my AOL email password, and have an AOL application password ready to use, but never get asked. I’ve turned off two-step verification in AOL, but same Thunderbird behavior. I’ve got multiple computers, and this issue is the same on all. I’ve had no problem adding a Gmail and SBCGlobal.net account. Thunderbird is 144.0.1 (64-bit) release. Windows 11 Home, version 25H2. I really don't want to give up Thunderbird, but I need this account badly.

I have tried several different approaches to correct this "mailbox://nobody@Local Folders/Archives" to set up my local folder and reduce my providers quota. but I havent been able to change it. Has anyone been able to fix this and direct it to a local NAS folder?

When I attempt to search for emails with a date (such as after Sept 30, 2025) in the INBOX plus subfolders (checked off), it only returns those in the INBOX. There are emails in subfolders dated after Sept 30, 2025.

If I search for a word without any date, it lists all emails. If I add a 2nd condition with a date as noted above, only the INBOX is displayed. Is this a bug?

I have two questions.

1. Right now I cannot receive messages automatically, which always has functioned. Now I have to shut down my e-mail and then reopen it, after I´ve done that I receive new messages. But I really will receive them automatically.

2. In the map Archives have all my saved documents been missing. I have six different maps in the Archives map and all saved information are now gone.

What has occoured? I hope yo can help me.

Kind regards, Carina Jonsheim

Hello,

I have used thunderbird for years. I have several email accounts on thunderbird. I own a small company with a private domain. The last [work] email both my employee and i received in Thunderbird was on 10/27/2025. The emails just stopped arriving in our inboxes. We can both access email through webmail. Personally i am still able to access all my other emails (gmail.com, comcast.net).

I checked with Hostgator and my thunderbird email settings are correct.

I did not have a SSL certificate so i have just onboarded that feature (not sure if that has any relevance to our current predicament).

Thoughts on how to troubleshoot this problem? Is it possible Thunderbird has made a recent software change?

Any ideas appreciated.

Thanks, Melissa
