Thunderbird won’t open because it wants a Primary Password which I have never had to do. I went on another computer (the one that I am currently using) and generated a password for Mozilla. I tried that but it still would not open. I have restarted the computer 3 times. When it asks for the pass word, I have entered the new one for Mozilla with no success. I have tried the one for the main opening of the computer with no success. When I close the small window that asks for the Primary Password, the spinning beach ball of death shows up and eventually (maybe 10 minutes) it has to be forced to quit.

Hello Due to a massive cluster**k this morning, I changed my password by accident I think I've now got everything working again, except that Thunderbird cannot sign in to my Google Account What I don't understand is that I have a password with normal and special characters and numbers, but the Oauth2 password is very different of course How do I know what to change my Oauth2 password too? Or perhaps the question should be how do I now generate a new one that goes with my new "normal" password Thanks in advance for any help

We can access our Orange accounts directly (www.orange.fr) and deal with our emails using passwords stored by Password Manager. We can not sign in to Orange through Thunderbird. The passwords saved by Password Manager are not recognised. Orange have introduced a system that produces a 23 character Password which is then entered into the password field in Account Settings: this is supposed to be permanent and unique to the account. When I followed this procedure I got the error message 'Incoming server already exists', for both IMAP and POP3. We are on Windows 10 and Opera; Can you help please?

This past week I started having a problem accessing URL's embedded in my emails from the Thunderbird interface. When clicking on the URL reference, nothing happens. I have not changed anything in my settings recently. Running Windows 7. I know my email server is working since this works when using my AT&T mail handler. I did have an issue with a Trojan virus that was cleared up with Malware program (i hope). I checked all the parameters of my mail handler and saw nothing that might cause this problem.

Cannot send emails from Thunderbird to a Yahoo server. Receiving emails from this server is working. There are several options for configuring the connection to this SMTP server. Server name, port number, user name, authentication method (ie OAuth2), connection security (using SSL/TLS). There is also a password required. When I try to send a message to this server, I get a login failure with options to reset my password. Since I had a working configuration, I retrieved the password from that and tried to reset it. That did not fix this problem. I am not sure if this is a sign in issue or a missmatch of the configuration parameters. I have tried several combinations of those with no success. This server is on a Yahoo machine that reserves ports for AT&T service. If I use the Yahoo interface for email, that will work, possibly because it is going into different ports on the Yahoo machine or my sign on with them is easier to establish. I prefer the Mozilla email handler to the Yahoo/AT&T handler, so I hope I can get it working again.

After a re-install of Thunderbird the Message List does not appear in columns, and there is no label bar at the top of the Message List to allow sort by date, sender, topic, etc.

How do I get the Message List to appear in column format again?

Thanks in advance.

‘I can login to Orange website & read my mails: Thunderbird, using same password, gets "Authentication Failed", This on 2 accounts.’ for ‘Thunderbird’. This is a recent problem, occuring after a series of"Account blocked , due to suspicious activity"

Hello. I have been unable to send email from one of several POP accounts on Thunderbird (v 115.18.0). I believe this occurred after Network Solutions changed the SMTP server for that email account. I am able to send email from my Gmail IMAP account setup on the same Thunderbird program on my PC. I have tried all the port and authentication settings for SLS/TLS and STARTTLS, changed/updated passwords, etc. I do not get any error messages, just never receive the test email I send to my other accounts. I updated the SMTP server on my iPhone mail app to the new NetSol SMTP and it works on that platform. I just cannot get it to work on Thunderbird on my PC. NetSol support said to delete account and start over which is not possible as it is my business email account. Also, the inbox is too large to back-up to an external drive. Any suggestions? Thanks in advance. John

Running "Mozilla Thunderbird v115.18.0 (64-bit)" on my Windows 7 laptop. I want the Inbox to display "Headers" such as "Date", "Size", etc. But I cannot seem to make this happen. Please help me. Thank you, Ron

The thunderbird server seems unresponsive and doesn’t recognise my password - what can I do? I can get my emails on my iPhone, luckily, but feel safer from scamming when opening them on my laptop. Please advise - thanks. Ps I have recently donated to Thunderbird!

Bonjour, Pourquoi actuellement tous les messages que j'envoie avec ma messagerie Thunderbird depuis mon compte FREE sont-ils identifiés comme spams par mes destinataires GMAIL ?

This just happened today. I'm using Windows 7 and Thunderbird version 115.18.0 (32-bit) . No settings have been changed and, there have been no problems signing in to my accounts until today. (I have a few accounts handled by Tbird.) The Microsoft sign in window comes up for me to sign in but there is no longer an option to sign in with your password so, I can't sign in and use my accounts in Tbird. I did click on "other ways to sign in" but no "sign in with password" there either.

Thanks for your help,

P.S. Wow. Crazy stuff. I closed Tbird and reopened it and, the previous Microsoft sign in window came up with the option to: "sign in with password". I am assuming it was fixed by restarting Tbird. Anyhow, "back i business" again.

I've downloaded Thunderbird in office PC and on PC at home. Almost I working in office PC or web mail but when I open Thunderbird at home, all my email lost in web mail and it's happened for such times. Is it a setting problem?! or, if it will be happen if using Android version ?! Thank you for your kindly assist!

I am unable to access my mails on Greenby with Thunderbird and I suspect the password is incorrect. I can read my mails on the Greenby server and know the necessary password but cannot work out how to enter this into Thunderbird! As I am no expert, a simple guide would be most appreciated! Thanks in advance. Roy

Hi. My main email address was accidently removed. All my previous emails are stored locally thanks to Thunderbird IMAP syncing up to now. I'm currently in touch with my ISP in order to restore my email address. This will be done in a few days : I am going to get my email address back, but all the emails on the servers will not be restored. Therefore, when the server is restored, it will be empty.

I fear that when it's done, during the next IMAP sync, my Thunderbird will delete all local emails.

What can I do to prevent that, or circumvent it ? I would like for the local state to be uploaded to the server, not the distant state to delete everything locally.

I've been using TB for many years, and without warning, when it tries to down load my mail from the Proton mail server, it says it can't find the folder "Inbox". I've tried to "repair" that folder a couple times unsuccessfully. I've restarted the TB program a couple times, but nothing changes. The error shows up on the bottom "instruction line". I've gone through all my settings and find nothing amiss. Not sure where to go from here. -- Just noticed that I had about 80 emails in that Inbox folder that are now missing completely. Normally, I move read emails to there respective folders, and leave important ones in the Inbox for followup. One significant note here, is I'm still using Win 7 premium. So far it hasn't been a problem. Thanks a bunch, Gerald

I've used TB for many years, and keep it up to date. But it suddenly stopped downloads from my email server. Normally everything comes into my Inbox folder and after reading, they are either put into their respective folders or deleted. I had maybe 60 or 70 retained for later attention. (Like due pymnts)

I've tried everything I know, even the mail server connection, but somewhere in the process, I lost everything that was saved in the "Inbox" folder. I got to looking for the profile file, and only found 1 that was recently dated. Not sure if a rebuild would be advisable. Nearly all my (50+) folders show up as normal. Just can't find why the Inbox isn't recognized.

I tried using TB in both safe mode and troubleshoot mode, to no effect. I DO have win 7 Ultimate and hasn't ever been a problem. The error message I get is: "The mail server for account ***** responded with 'mailbox INBOX does not exist!' The name of the folder is "Inbox" as opposed to the capitalized version, but nothing has changed for years, and never been a problem. Go figure??

After _years_ of use and storage, I'm really hurting without it. Any help or suggestions would sure be appreciated. gshantz

i can still see my email folders but these popups appear for each email account in thunderbird (mac osx high sierra) never saw them before so seems something has been compromised? tried to screencap but it's only showing about: url but urls zip by and was able to catch the url a few times earlier but not now.

"thunderbird is up to date" for mac os x high sierra

When I highlight multiple messages for deletion; it can take up to a minute to respond; when I am working with gmail or proton, the deletion is immediate. When I am accessing Reagan with browser, the multiple deletions are also immediate. Appears to definitely be a handoff issue. Suggestions? I use Thunderbird on 2 win11 os and 2 linix mint 2.1 machines. I only delete and store to local on one machine (win11) ver/build 23H2: 22631.6199.
