Thunderbird Community Forum

Trying to setup Thunderbird for wife’s new laptop… Her 4 separate email accounts with auto setup for the IMAP server info without issues. One account however will not – VERY frustrating as this works fine on her old laptop. Thunderbird setup now appears to have an extra (4th) field required when setting up the account: Usually, its just name, email address and password. I see there’s now an extra box titled ‘Your Login’ being required for auto login. I have no idea what this field should be set to. Also, when I attempt to do a manual setup for the account, the port numbers and server names shown on the internet are completely different to those used on auto, and still get rejected. Doesn’t help that MS trying (and succeeding) to confuse us with all this “Outlook vs Outlook Classic vs Outlook.com”. My wife is unable to continue her work until I get this sorted:-( PLEEEAAASE can someone help me setup this xxxxxxx@outlook.com email account in Thunderbird as an IMAP account?

I have deleted an email account, then I made sure that the saved password and any traces of the account are gone, but every time I launch the program a window pops up with this message:

Authentication Required - Mozilla Thunderbird https://ha1012.raiolanetworks.es is requesting your username and password. (and the account I had before deleting it)

How can I stop that window from appearing again?

Thanks!

I have seen this problem with roadrunner listed in the forum but my situation is a bit different. Neither my wife or I can send or receive roadrunner emails with different machines. She uses a Mac (sonoma 14.8.7), up to date, I use Linux Mint ver 22. We also have iPhones and iPads. none of these units send or receive emails for the last 24 hrs but all worked just fine before. Spectrum says it our problem not theirs. The tech person at Spectrum said they partner with Thunderbird but they did not know of any changes made.

I have changed passwords used different routers and anything I can think of to connect but the devices now all time out when trying to connect.

I have one desktop using LINUX MINT with its issues. using Thunderbird mail program. I also have a DELL laptop WIN 11 using Thunderbird.

Is it possible to sync the two (2) accounts to save emails on bothe CPUs?

Regards,

Christopher

Help setting up first email account (protonmail.com) Keep getting: "unable to login at server, ether config, or credentials" error.

I want to use thunderbird on a Windows 11 laptop. Tell me how to connect Thunderbird to send and receive emails from email account, jds@sefcik.net, hosted at smartmail.buz.net.

New user - I recently moved thousands of messages from my inbox to a local folder.

At some point, Thunderbird asked me to compact folders and I said yes. I noticed today that I am now missing about 13 years worth of messages from my local inbox folder.

Since I moved them, it deleted the messages out of the original inbox (I also logged into that account via the web and they are not located in the trash on the server either). There are now only a handful of messages there.

Does compacting mean that messages are deleted? Everything else I read said specifically that it would NOT delete messages. Any tips on how I can recover some really important messages? (It deleted about 13 years worth of messages from early May 2026 back to mid-2013, so there are recent messages in there I really need!).

Steps already taken: I tried using "repair folder" and that did not work. I do not have any automatic filters set up. I tried locating my Profile, and moved the "msf" files to my recycling bin, as I read that deleting the msf file would rebuild the index and display emails that had disappeared. Nothing changed. This was new for me so perhaps I did something wrong? I haven't emptied the recycling bin yet so the files are easily retrievable if necessary.

I have been using T-bird for years successfully until lately. We have multiple email addresses in Comcast and Gmail, but lately our passwords that we have been using and know are correct because they are written on paper and Keypass, are being changed somehow so that they will no longer work. When we look at the saved passwords in Thunderbird we see some have been changed on a certain date that we did not do, and the password listed now must be about 200 characters long. Then when we go to change the password, it may be listed as changed. Then when we try to send a message with that email address, we get an error message saying, for example, smtp.googlemail.com and a wrong username/address completely. I can find no way to correct the username email in any settings in Thunderbird. I have searched the Thunderbird HELP files many times, but am unable to find any of this addressed anywhere. After trying to fix these problems for most of 3 days now, I have get rid of Thunderbird for an email client that works correctly!!!

I always get: "newmsg Trojan:WIN/SuspiciousAttachmentScript.a" and "C:\Users\newb\AppData\Local\Temp Trojan:WIN/SuspiciousAttachmentScript.a" from Mcafee when I open Thunderbird. I'm only getting this in Thunderbird and suspect it's a false positive of some kind. It's still worrying and I'd like to eliminate this. This has been going on for a couple of months. I've run several cleaners and anti-virus programs on the system, but it still returns.

thanks

Have a new computer and when they transfered my information they didn't do my email. I finally got found it an downloaded it but now it won't accept my password. Plese help I'm getting desperate. Thank you Mary Ward

Threading - why does it keep coming back? I have just realised it's back again on my Thunderbird and I never knowingly turned it back on.

Why does Mozilla keep trying to force it on users?

This has been an annoyance for users for several years now and the message has still not got through it would seem.

For an open and user-facing organisation, this is strange behaviour that I just do not comprehend. Include it if you want, but make it optional and easily so.

I know this is only the community forum, not Mozilla, but one would think that a wise organisation would keep an eye on what their customers were saying & feeling.

Hello,

Despite the fact that I have set Thunderbird to display messages as plain text, my needs are not being fully respected. If the message contains some form of markup, presumably HTML, the font size is not what I have chosen. Generally, the font size is smaller than what I have specified in the Thunderbird settings.

This is unacceptable. It is a usability / accessibility issue. If the user chooses Plain Text and sets a font size, they have done that for a reason. Which is accessibility. If Thunderbird ignores the needs of users and applies styling rules to messages, that is a failure state.

Is there some way to actually, truly, absolutely display all messages as plain text in a specified font, weight, and size? If not, what is the protocol for reaching developers so that they can respond to this issue?

Thank you

It has been going on for two days. I tried restarting in troubleshoot mode and it didn't turn on the "Show Password" button. The version of thunderbird I'm using is Mozilla Thunderbird.

I have saved my selected emails in different folders under Local Folder based on the subject of the email. Now I do not see one such folder where I had saved several emails for that particular subject/topic. Need step-by-step to restore that FOLDER from C:\users\myname\AppData\ ???

My issue described may not be Accessibility I chose in Topic above as that was the closest to match. Basically I am missing that Folder as I might have accidentally deleted from the current file that displays when I click open Thunderbird Mail.

I have a small office with 5 stations to access our one email account and we'd used thunderbird for years, but the lack of integration between the stations meant we changed to Outlook and of course that's a shitshow, so I'm coming back to ask you my self (rather than the tech guy) if there's a way to set up thunderbird so that if desk 1 opens and responds to email 17, that all the desks can see both that it happened and access the responce that desk 1 sent.

We have an IMAP email account hosted locally (as in, not a gmail account, or the like).

I'd be more than happy to pay for a piece of software that I could use. I've used Thunderbird (and Eudora) for decades and I'd like to continue to support it. But moreover, I'd like an email server that doesn't limit my account size (I use email for "corporate history") and one that would allow my individual staff members to see everyone's activity in the email server.

I had most recently (like 6 months ago?) been using thunderbird. My Tech guy said it was the most current version, but I couldn't tell you what it was.

We run on Windows -- most on 11 but a couple still on 10 until I can take the time to set up the new computers.
