Thunderbird Community Forum

I changed my Gmail password and Thunderbird asks me to enter the new one, however, it displays my email address with a lit 'Next' button but the button doesn't take me to the next screen to allow me to enter the password, it just flashes, no matter how many time I click it.

Have removed password entry in security. Tbird then hangs on 'Connected to ....', but does not offer chance to put in new password. So I can see inbox and emails on BT but not through Thunderbird. Solutions appreciated.

Currently unable to set up to an existing account on a new laptop. I’ve verified user name and password on the old laptop, but these don’t work when setting up the new one. The Thunderbird set-up wizard found my configuration in the Mozilla ISP DB, but can’t verify it. In other words, it won’t accept my username or password. I’ve done this for both IMAP and POP3, but it makes no difference. I’ve confirmed user name and password for both smtp and mail folders, and tried them in setting up. However, on the new laptop, Thunderbird doesn’t ask for user name, but just the name as displayed to others. Once I get set up, I’d like to copy my archive into the new system. One thing at a time…

Microsoft tell me that I must use OAuth2 for my accounts, else I'll be locked out.

Server is imap-mail.outlook.com. If I select OAuth2, then I can't receive emails unless I reset back to Normal Password.

I'm also supposed to set my SMTP server (smtp-mail.outlook.com) to OAuth2, but this isn't an option on the drop down list.

Help, please!

When I send a message to anyone using the blind copy option, both the name and email address appears on the recipients copy of the email. This first started in December ( I send Quarterly mailings to several groups.) I have used this program for last couple of years and never had this problem before. What has happened and how can I correct it.

It looks like they are being sent as a blind copy, but they arrive with the email address showing.

From Sept-16-2024 Microsoft will deprecate Normal Password and require OAuth2 authentication on its email accounts accessed from Thunderbird and other clients.

I'm trying to convert my hotmail accounts on Thunderbird to OAuth2 authentication.

Server Settings Authentication can be set to OAuth2 because OAuth2 is an option in that menu.

But SMTP Server Authentication cannot be set to OAuth2 because OAuth2 is not an option in that menu.

Both Connection Security methods ( Inbound and SMTP ), are set to STARTTLS.

See screenshots, thank you.

I have changed the privacy settings as suggested in the help guide, but any image I text to my e-mail is blocked. They can only be double clicked on the footer to open them in another application. Is it possible to have them load automatically in the body of the e-mail?

Hi, I have configured 2 accounts for E2EE using OpenPGP. I can send signed emails &/or encrypted messages between the 2 accounts. However, if I send a "normal" message i.e. no signing & no encryption selected, it arrives as not signed (correct), but encrypted according to the "Show message security" icon. If I send a normal message to an account that has no known encryption setup, then the message arrives and the "Show message security" button is missing (correctly).

Any ideas why this is happening? Thanks for your help.

Hi, 3 weeks ago I suddenly could not log in to my email without errors.

First I get a Google screen "Choose an account" showing the three Gmail accounts I use. I select the first one.

"Mozilla Thunderbird wants to access your Google Account". This refers to calendars. I take the Allow option.

Then I get the message "Warning: Potential Security Risk Ahead

Thunderbird detected a potential security threat and did not continue to localhost. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details."

When I close this window I get another Google screen .

"Mozilla Thunderbird wants to access your Google Account". This refers to i) mail, ii) contacts, and iii) calendars. I take the Allow option.

Then I get the same message message "Warning: Potential Security Risk Ahead

Thunderbird detected a potential security threat and did not continue to localhost. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details."

This process cycles through the other two emails. Then I get and authentication failure message.

I have seen hints that this might be a certificate issue but I have tried in vain to find certificates stored in Thunderbird.

Any help approeciated.

Thanks

I'm setting up a new computer for an elderly lady. On her old computer she logs straight in to emails. But I want to set up on new computer but it doesn't recognise her email address or password - both are correct. Old computer is not Wifi so modem is connected by a lead. I've been transferring the lead to the new computer - but maybe I don't need to do that? Would that be confusing the configuration?

After upgrading to Thunderbird 60.2.1, I can no longer send messages. I'm running Linux 4.15.0-38-generic.

I get the attached error saying that I have problems with STARTTLS SMP. However, I have my connection security as SSL/TLS (second attachment). I haven't changed anything for years on my connection security. I successfully sent emails yesterday. Sending still works on my other machine (Windows) with v 59 and the same settings..

I use Thunderbird 115.12.2 (64-bit) with Hotmail, using a local account on Windows 10. Microsoft is introducing 'modern authentication' on Hotmail, and I want to be ready for this, but I cannot follow the guidance at https://support.microsoft.com/en-gb/office/modern-authentication-methods-now-needed-to-continue-syncing-outlook-email-in-non-microsoft-email-apps-c5d65390-9676-4763-b41f-d7986499a90d

If I try to alter my existing Thunderbird Account Settings for my Hotmail account, the authentication method for Outgoing Server (SMTP) is shown as Normal Password but there is no option to change it to OAuth2. If I delete and recreate my Hotmail account in Thunderbird, I get an error message from Microsoft saying that I cannot log in because my browser is not set to allow cookies -- even though I believe I have set both Thunderbird and Firefox (my default browser) to allow cookies.

I have just completely reinstalled Thunderbird v115.11.1 after uninstalling the previous installation. There are two problems, possibly linked to a faulty or missing setting.

Remote images will not display, even after specifically enabling remote images for each email, or after turning on "display remote content" as a default. Also it claims there is a potential security threat with Thunderbird's own web addresses: "live.thunderbird.net." and "addons.thunderbird.net.".

I have attached screen-shots of the error messages, and of a thunderbird email that fails to display its images.

Multiple people use this pc and Tunderbird. When I open Tunderbird it show the mails I had last time I openend it. I would like it to be hidden until I enter my password so only I can see the emails. Can anyone please help?

I have not been able to make a connection to the mail.comcast.net for a day now. I see the connecting bar at the bottom but get a failure that it failed to connect. I cleared the password manager. but no popup appears to enter my password in. So without authentication, it cannot get the email. I can't force the login popup to appear to enter the new password.

Server settings are fine, I am using POP3 which is remaining a valid choice. I use avast, current version (autoupdate) Thunderbird is current too. My firewall is WindowsDef, but Thunderbird is on allowed list. I have briefly turned off both Avast and still no connection. I', not sure if defender is blocking even if I selected it. Comcast of course denies anything as the web interface is fine ATM.

(this is not the router or modem as another laptop using thunderbird (probably older as it's my mother's) opens fine. I have done little else for the last day and have run out of things the check, help>! Thanks

My PEC mail sends me this error:

Sending username failed. The mail server mail.postecert.it responded: unsupported SASL authentication method

Can this be solved? Thanks

I had 2 gmail addresses in Thunderdbird. For the first one, I just changed the password authentication method to Oauth2 in the server parameters and it instantly made the replication work.

For the second one, I unfortunately deleted the account and couldn't recreate it, even with the "less secured application" set on in the Google Account parameters. I also tried to activate the 2 level connexion method and generate an application password but couldn't find any way to use it in thunderbird. Therefore, I'm stuck with Webmail Gmail application. I have noticed that the connection has been bllocked by Google (see image)

Hope some body can help (this is related to Google security reenforcement actions but seems that Thunderbird is not up to date on this issue).

Please find attached the first page of my troubleshooting info.

While using Thunderbird, it mysteriously stopped connecting to Yahoo Mail. This happens every few years and I think it's related to Oauth2 credentials.

I generated a new secure mail key and copied it into Thunderbird but that didn't work. So then I checked online, and one of the steps in the Thunderbird instructions is: "Select 'Server Settings' for mail account; Set incoming server 'Authentication Method' to 'Oauth2'; Click on 'OK' ". But Oauth2 isn't one of the options. The choices are normal password, encrypted password, Kerberos/GSSAPI, and NTLM.

I'm using POP. Tbird version 115.11.1.

Hello: t-bird 128.3.0 esr 64bit. W11pro laptop (dell). MalwareBytes Team up & running & up to date, many yrs. Problem: an attachment, which I tried to completely remove, keeps "coming back" in emails, in a specific inbox (only 1 inbox, of 1 acct). Other t-bird mail accts do NOT have this issue. -The "coming back" means that I delete the attachment and empty the t-bird trash. The attachment then plants itself in another email. -Once planted in an email, it appears the attachment completely erases the body of the text of the body of the email. -The attachment, when opened, is an image of a family. That is it. It is not of any family we know. It is always the same family. -I "found" the attachment (using a search program) by name, "img_2068.jpg" . Deleted what I thought were all occurrences of this file on the laptop, which were only 2 files, both in temp folders. I deleted all temp files from the laptop, emptying the w11 trash & also running w11 file deletion apps. Malwarebytes has never detected this corrupt image file. -After making all those deletions, I ran the search and the search prog did not detect the file. But I reopened t-bird and the corrupt attachment has attached itself to another email, and the same behavior recurs (I delete attachment, corrupt attachment attaches itself to another email).

-Also please note, the emails that had the corrupt attachment attached (have been previously not having any attachments), do exist on the mail server (imap), where you can see the the message body/text. And again, once the corrupt attachment infects an email, in t-bird, that email's body/text goes blank, there is no longer any message to be seen. There is just the attachment notice at the bottom of the email border, to be clicked on to open.

Is the only solution to completely back up all the t-bird accts (address books, sent, drafts, etc.) and reinstall t-bird program (and/or profiles) ? Or, would an "easier" way work (or has worked), like simply deleting the inbox of the "infected" account? I would then download the uncorrupted emails from the imap server in a new inbox. But I don't know where to find this corrupt file, there is apparently no "attachments" folder for t-bird. And again, searching by corrupted attachment file name, and removing it as above, has apparently NOT removed all instances. I don't know how else to find it.

Please advise. Thank you.
