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.

Starting from the app menu button ≡ or the main menu, choose Tools -> Developer Tools -> Error Console.

Copy the text given below and paste it into the Console.

If using version 78 or later, copy and paste the following text: openDialog("chrome://pippki/content/resetpassword.xhtml"

Click the Evaluate button.

If you do not see an 'Evaluate' button, press Return or Enter on your keyboard.

When prompted with the confirmation dialog box, click the Reset button.

The problem is that I don't see an "EVALUATE" button

This after I upgraded to the latest version of Thunderbird.

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?

Hello Community Please help me to start again with Firefox from scratch. Last Month I downloaded Thunderbird email app and set up with a new email account using mailfence. Now I find that my mailfence email address was only a free trial and I have to pay to continue to use. I now wish to set up with my original free email with gmail. I did uninstall the Thunderbird app and then installed from fresh. Unfortunately it still has the mailfence email remembered in the Thunderbird App. How so I start again from scratch using my gmail account instead of the mailfence account that has now expired? Thank you in anticipation of you help.

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 ?

For past 24 hours only, I have been unable to open email attachments. v115.7.0, however last update was 31/01 and has worked perfectly until now. Still use Windows 10.

Double clicking on attachments does nothing, other than popup software option for formats without specified defaults. Either way, no indication that attachment is opening.

"Save as" is saving attachment document to target folder, however trying to open these errors, suggesting document is corrupted or in incorrect format.

Have tried restarting system to no effect; likewise error continuing in troubleshoot mode. Cannot see any obvious settings that would impact this, nor have I consciously altered any of these.

I'm certain this may be an easy fix, or my own error, but this is eluding me.

Beginner or Luddite Question - I am seeking something like outlook, but NOT OUTLOOK. I lost so many contacts, connections, data and usability from that POS. Let's be clear. I am seeking something that will support the following: -having multiple email addresses for multiple businesses and organizations all in one place. - the ability to have individual signature boxes for each email address supported (as many as 12) - Something that won't crash on me and F*** up everything -I don't care if I have to pay, I want everything in one place easy to utilize. - I want a third-party VA to be able to get in under a common sign in and work under my name

Can Thunderbird do all this and more without having to hire a $500 per hour techie? If someone is for hire, how much is the charge?

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.

I'm using ThunderBird 115.7.0 and Windows 10.

'''When are you going to add Categories to Contacts? '''

It is the only feature holding me back. I use outlook for Windows and I am able to sort my contacts by categories. In addition, I use a syncing software called Companion Link/Deja Office which syncs those contacts with those categories on either my iPhone or Android. This allows me to focus on targeting specific people for either personal or business use. Your software has that feature for calendar items. Why not integrate that same feature for the contacts which has a higher degree of importance. I see that a multitude of people have asked for quite some time already even offering to donate money if implemented.

Thanks so much :-)

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!

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?

I had a huge problem with M Outlook. In addition it has locked me out of my Office 365 package and I'm not getting help or support. Luckily I had backup completed before the problem. I changed to Thunderbird (using pop3), which I find very good. The back up is approx 8 GB but with many duplicates which I need to clean up. When I click import it seems to limit the file size to 2 GB. How can I import this backup file into Thunderbird to enable me to access the emails, clean up the many many duplicates and reduce the size? I await help, Thanks in advance

Back in 2015 someone asked about the fact that emails are not marked "as read" once opened but I don't think the answer was ever fully given. They were told: "This option has always been available and I use it. via Menu Bar Tools > Options > Advanced > Reading & Display or via menu icon menu icon > Options > Options > Advanced > Reading & Display select: 'automatically mark messages as read' Select: 'Immediately on display' click on OK When you select/left click an email in the list, it will auto open and display in the Message Pane below the list. If you use double click, it will auto open in a new tab or window depending upon what you selected. In bth instances the message will be immediately marked as read." Here's my problem with that .... I don't use the "Message Pane", I don't like it. I have my incoming messages set at "table view" and they are all just listed down the page by date. I don't want to see what's in the email until I actually open it....but, once I open it and read it when I close out of it the email still stays BOLD in the list....this didn't used to happen, once I read the email the BOLD went away. When I use the "automatically mark message as read immediately on display" then new emails are not in BOLD so I can't tell if they've been read or not. Bottom line, is there a way to have messages marked "read" AFTER they are opened WITHOUT using the message pane??

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.

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.

Suddenly I can not receive my emails on Thunderbird. They do show up on my cell phone. When I send an email, I get the following, "Your message was sent, but a copy was not placed in your Sent folder due to network or file access errors. What can I do?? Ed PS I will get your email response on my cell phone, thank you.

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?
