I need to change my password however I am not succeeding.

I am trying to change it from the following path : Settings - Saved Passwords.

Once in the above path, I type in my new password and press close.

I then close thunderbird and when re-opened a pop up window appears to type in the password. When typing in the new password, the following error comes up:

Login to server secure.emailsrvr.com with username ------------- failed.

For thunderbird to continue working, I need to enter my current 'old' password. Somehow it is not recognising the new password.

Can someone please help ?

I have updated my password on my IMAP server. I cannot find where to enter the new password on the server settings. There used to be a box for this. It asked once when I logged in but dosnt ask again.

This must be one of the most basic settings that needs occasional updating but no clear location where to do it?

Its now made thunderbird un useable and have migrated across to outlook where you just type in the new password.

I have 4 Suddenlink emails being checked with Thunderbird. I have been running my current Thunderbird configuration for year. I have not changing anything on my end. Two weeks ago, I started getting a login to server pop.suddenlink.net failed popup on one of my Suddenlink accounts. I have logged into the email on the web interface and changed the password on the web and in Thunderbird. I am still getting the login to server pop.suddenlink.net failed. I have rest the password on the web interface a few times, but still cannot get it to work in Thunderbird. The other 3 Suddenlink accounts are still working fine. I have Thunderbird running on a second computer at work checking the same accounts and I am having the same problem with the same Suddenlink account.

Dear Thunderbird: I have lost my password for gerry@bablaw.com. Because I don't have the password for <redacted>@bablaw.com, please send any reply to <redacted>@gmail.com, or a text message to <redacted>. Thank you. Gerry Blodgett

The Automatic Account Configuration in release 138.0 (64-bit) is not working for me on my WIN11 laptop. When I try to add my Comcast Email account to Thunderbird it finds the information for Comcast in the Thunderbird ISP Database. But when I continue by selection "done" the Credentials Window opens but fails to connect with this message:

Unable to connect

The connection was refused when attempting to contact localhost.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Thunderbird is permitted to access the web.

This process works perfectly on my 2 other PCs running Win10 with Thunderbird release 128.10.0ers I would really appreciate and ideas or steps to correct this issue. Thank you

Old Mac on High Sierra, i.e. Macos 10.13.6. Thunderbird 115.18.0 (64 bit). Regardless what I try, TB won't connect to mail server.

I have no idea what kind of encryption the password may have. Have tried all options. No go.

Here's what I have (well, due obvious reasons, details are fabricated):

Mail address: 134@12345.com Incoming server: mail.12345.com Password: 12345 Username: 134@12345.com Outgoing server:mail.12345.com Password: 12345 Username: 134@12345.com

As I wrote: have no idea whether password is STARTTLS or SSL/TLS or whatever.

How can I make TB connect?

I cannot login to Thunderbird. I have a Telstra Bigpond email account. I have set it up for imap using the Telstra settings. My password is correct but it is not accepted and I cannot login.

I have tried to install thunderbird on an iPad Pro to transfer email etc from MacBook Air and now neither one will retrieve new email messages. Responce is account has been blocked / blacklisted.

I am using Gmail as my email hosting and connecting via IMAP. Has not been an issue for years now, but all of a sudden there is an issue with Thunderbird connecting to Gmail. It keeps asking for password, and does not sync. This all started yesterday 04/28/2025. Is there some sort of update? Is it on the Thundebird side or the Gmail side that I need to update something? I have not changed any of my log in credentials. Thank you for any input possible.

Just installed Thunderbird on a new Windows 10 laptop. Trying to get set up, I'm getting a message that says "Unable to login at server. Probably wrong configuration, username, or password. I'm pretty sure my password and username are correct, as I've been using the same account and PW for years, but on my mobile device, I entered everything the way I'm remembering to be right, but since the app on my phone autofills it for me, I cant be sure at this point {eyeroll}. I'm not quite computer illiterate at this point (I just learned how to take a screenshot on my laptop!), but not sure how to resolve the issue. The email account I'm starting off with is a NetZero account, and I'm assuming the auto-detect for the configurations is correct. Thoughts? Thanks!

I am having a problem when connecting to my employer's office 365 server. I'm getting an error that says the current command did not succeed. User is authenticated but not connected. If I connect to the same account in Outlook, it works as it should. Everything was working fine until about a month ago. I had not made any changes to the configuration, except for possibly a version upgrade. I am getting same error on all computers running Thunderbird. Two are Windows machines, one is a Linux machine. I am currently on Thunderbird 128.5.2ESR. I have seen solutions on Google, and I have tried deleting the account, recreating it and changing the IPV6 DNS setting in config editor to true. Has my employer changed something that is not going to let me in? I really hope not, as I cannot stand Outlook. Even more so with the new Outlook. Thanks much for your help and advice.

Due to a birst central heating pipe I had to move my computer system to another room. When I tried to re-login to my e-mail accounts on Thunderbird, I had no problems with my gmail account.

But I had problems with my other account: gerard@cict.uk. The server name is outlook.office365.com. One of my outgoing server settings is: smtp.office365.com. The e-mail address gerard@cict.uk was bought from Namesco, who appears to be using Microsoft, presumably Outlook. Unfortunately I didn't make a backup of Thunderbird (just saw that it is possible), although I do have backups of my work up till 15 december 2024. Can you help? When trying to get back into my gerard@cict.uk system I changed some passwords. Strangely, having changed them I couldn't log in (incorrect password).

I am depressed. I can of course continue to live, but I received about 100 emails a day. So reconstituting my system for gerard@cict.uk will take considerable time.

For over a year when I start Thunderbird I get "Login to server pop3.frontiernet.net" failed and it asks me for a new password. I have no clue. I have no clue where I get that.

Years back everything worked fine and I had a long history of email saved, then it all went to hell. Frontier mail hooked up with Yahoo!mail. A Version change with Thunderbird caused it to stop connecting to my [edited] @frontiernet.net account for quite a while then it was working again but started giving me the Login Failed and asking me for a new password until it would finally connect without my having given it anything. What should I do?
