Had to reinstall Thunderbird on my old Mac after wiping it (accidentally! :() and it won't let me log in--Says probably wrong configuration, username or password. Old computer logs in fine! Any help most most appreciated THANK YOU!!!!!

I've been having this problem for probably about a year now. I have 9 accounts (5 Pop3 and 4 IMAP), and the passwords are stored by Thunderbird. I click the send/recieve button and everything downloads...until it doesn't. I go the settings/ saved passwords and what was a long list is very short...it has the MS oauth stuff for outlook.com emails and nothing else.

Over time I've found a relatively easy workaround. if I click the offline button in the lower corner, eventually it will prompt me for all the missing passwords and I'll be ok. But I have to exit and re-enter Thunderbird for that to work. If I do it in the instance after a download failure...it just hangs.

I use Firefox, and I noticed it happened one time after a Firefox update and I thought that might be an issue, but that didn't happen on the next update. There is nothing overt or obvious with my computer that would explain it...no dropped connections or errors...

I will note that I generally keep the computer and Thunderbird updated...but not necessarily immediately after the latest update is released. Thunderbird is at 128.4.2esr now. Windows 11, 1 yr old computer.

I do he the Thunderbird data on a NAS accessed over a LAN. I've been doing that for a long time with no issues.

No other changes on my end see to be the issue. Any ideas?

Thanks for any advice.

I have not changed my email accounts or my Google & Microsoft usernames or passwords. A few days ago when I started Thunderbird, two Google pop-ups arrive reading "Mozilla Thunderbird Email wants to access your Google Account" demanding that I deny or allow it. Why might this be happening and how do I stop it? This does not occur with other email apps such as Outlook for Windows.

I have used Thunderbird for a long time and it's the best. However, I made a donation and all fell apart. Then I made another donation and still nothing works. Then I made another donation and it got worse. I am continually being asked for my password and when I type it in, it says that the password "failed". My password was changed by Comcast so I changed Thunderbird settings to the new password and it's not working at all. I haven't had email now for about 3 months. I've gone to Comcast and they say that all is well on their end. Could my settings be off on Thunderbird. I'm 83-years old and I really need help. My personal email address is SillySam@comcast.net. I also have LatonHigh@comcast.net used for historical research. Please help me.

I am trying to create a Primary Password but getting message: "Unable to change Primary Password" Using Thunderbird Version 128.4.1esr | Released November 4, 2024 under Windows 11.

I recently tried to set up Thunderbird to receive emails on my smart phone while on vacation. The phone was new, and I ran into all kinds of problems with it, including messing up most of my passwords. When I got home; I'm getting a sign in error on my email account, along with other problems. How can I reset to a new password so I ran open the emails that have stacked up?

I have an icloud email address in Thunderbird on my windows laptop. I changed my apple id password and the icloud email has stopped working on my laptop. It asks for a password and does not accept my new password.

hallo zusammen, ich habe heute versucht einen Chat-User mit Passwort zu erstellen, beim Verbindungstest kommt die Fehlermeldung: Passwort falsch;

Gibt es evtl. spezielle Anforderungen zum Passwort oder muss ich hier evtl. eines der angelegten eMail-Accounts benutzen?

Komme hier leider nicht weiter, danke für Eure Hilfe

ever since your last software upgrade, my Thunderbird acct has not allowed me to login. I keep getting message " Sending username did not succeed mail server mail.twc.com responded invalid username or password" for ‘Thunderbird’ I do not know how to reset my account. I have over 150 addresses I can't retrieve. I know there is no one to speak with, but I have no idea how to proceed. I have looked at "saved passwords" and there aren't any on the list. Thank you, Dale

I've tried several times to install Thunderbird but at the last stage, a message says my password is incorrect. There's no way of accessing my password to check it or choosing a new password. I don't know what to do!
