Thunderbird Support Forum

My Thunderbird has been working properly for about 30 years, but now refuses to open. Message received says 'Authentication failed'. This happens repeatedly (for at least 20-30 times) and appears to relate to my password. It suggests 'Retry' or 'Enter new password'. The 'Retry' repeats as before so I check the Saved Passwords and enter the one saved. I get the same message. I am using Version 115 and have been for some time.

Could this be related to a change of Profile? There must be a way to reset the password? I have checked all the settings and no errors appear, all settings confirmed.

I have thought about a Recovery Mode and seem to remember seeing a message that I do have that. I just don't know how to access it.

MacOS Sonoma 14.4 seems to have broken a number of apps. AFter updating to Sonoma 14.4 I experienced a great number of crashes with Thunderbird, so I completely uninstalled Thunderbird and removed all traces of plists, Application preferences, everything, reinstalled Thunderbird, and added back the two email accounts I use with it.

It now takes up to 30 seconds to start up Thunderbird, after which it happily no longer crashes, but obviously the startup time is unacceptable. I experience the same problem with Typora, and the developers there informed me that they believe the problem is with a Sonoma change that broke WebKit. I don't know if Thunderbird still uses Gecko or if the new version is WebKit. Please let me know if other Sonoma users have reported this problem or if it's just my system.

Hi, As of yesterday I am unable to send emails out. I keep getting this message below. I have gmail on same computer and that works fine. I am able to receive emails but can't send. Please help

Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) smtp.gmail.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again.

What can I do?

I have been using Thunderbird for years to access several @charter.net email addresses, lately administrated at Spectrum, which took over Charter. Everything was working normally until today. I can still receive emails, but when I send, I get an error message asking for a password: "password required for outgoing SMPT server" Manually entering a password in that error message box doesn't help. Spectrum support is not helpful beyond confirming that my email sends and receives normally as long as I access it on their website. Three clues: 1) Spectrum recently announced "new and improved" email. 2) One customer service person described my email addresses as "legacy". 3) My gmail address sends and receives just fine from Thunderbird as usual. Any insights appreciated! Thanks!

Hello, It's there any option/setting in mozilla thunderbird for drag and drop emails to local drive folder and save them under another filename that the standard "Subject" name? I don't know if i'm clearly enough, that's why i want to make a briefly description of the operation i want and the way the emails i want to appear in my folder. I drag and drop an email to my folder and this email has the filename represented by the "Subject" of that email. Can i change the way emails are saved ? Or can i drag and drop emails from one sender in separate folder ?

I can't open my Excel attachments in ThunderBird.

Is there a setting I need to open. The one I use by default only gives me word, wordpad options. or choose my own, which is still word and wordpad.

Thanks for any help.

Certain email newsletters that I signed up for (and verified) go directly to trash. I have no Thunderbird filters on nor does my internet or computer. How can I fix this? I switched from Outlook but sadly, will have to go back if this isn't fixed.

I had emptied my spam and junk folders but unfortunately I had marked up one email address as such which I need to undue, but I can't find where the list is. Where do I find it please?

There is now a new line of all my emails just below the T/bird menu. I hate it! How can I revert to seeing all emails separately in the main email body and losing that line?

I have already several times asked my question and have received no reply so far. Could you please reply to my e-mail: jean-pierre.biber@natcons.ch Here my question again: Good evening I have been using Thunderbird mail for ages, and now suddenly diverse thing don't work anymore: I can't chose my signatures anymore, the language correction does not work anylonger, and when I print things they come out wrong. Can you please help me fix that? My email is jean-pierre.biber@natcons.ch Kind regards Jean-Pierre Biber

After updating to TB 115.5.2, we keep getting the following error message when we try to send or forward an email: Sending of the message failed. An error occurred while sending mail. The server is not responded. No such domain at this location. Please check message recipient "xxxxx@gmail.com" and try again. I get this error on all emails we try to send. We get this same error on my spouse's computer also that we use Thunderbird with. I have already checked settings with my ISP and the POP settings are correct. We can use other mail servers such as outlook.com and gmail.com using Thunderbird. ISP is cis broadband. have checked firewall, have uninstalled Thunderbird and re-installed without solution to problem. ISP has checked port to make sure it is not blocked.

incoming emails do not seem to be effected.
