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.

A while ago my long-time hotmail account stopped working on two computer with windows 10 and one with windows 11. Last night, I looked up an article that said I have to use Oauth2 instead of normal pw. I made that change on the windows 11 machine and a popup occurred that wanted the number from the google authenticator on my phone. I gave it that and it checks mail now just fine.

This morning I went to one of the Windows 10 machines and did exactly the same. I tried some different server names online and tried some, but after a while I started getting a little window that asked my email address and pw. I put my hotmail address in and got this message:

Microsoft Accounts or personal email addresses don’t work here. Make sure you enter your work or school account (e.g. user@contoso.com). If you want to reset a Microsoft Account password, click here.

Now this is the very same hotmail email that worked on windows 11 with the same server settings last night. It still works.

Now, on the windows 10 machine with those same settings, I get the blank extra window. The extra window appears, does not populate, and disappeared.

It is: https://login.microsoftonline.com/common/oauth2/v2.0/authorize?response_type=code&client_id=9e5f94bc-e8a4-4e73-b8be-63364c29d753&redirect_uri=https%3A%2F%2Flocalhost&scope=https%3A%2F%2Foutlook.office365.com%2FIMAP.AccessAsUser.All+https%3A%2F%2Foutlook.office365.com%2FPOP.AccessAsUser.All+https%3A%2F%2Foutlook.office365.com%2FSMTP.Send+offline_access&login_hint=redacted@hotmail.com

I had no opportunity to do what worked on the windows 11 machine just last night. I cannot check mail on hotmail on this windows 10 pc. I took all the updates available to Thunderbird and firefox. TB is 115.11.1

I'm stopped. Why would it work on one pc and not another? Oauth2 on the windows 11 asked for authenticator. On the windows 10 it never asks.

Our app sends an email advising the specified individual to note a series of images presented in three rows of nine. The rows display in Gmail via Windows->Chrome, via Android, and iOS with a Yahoo account.

But not in Thunderbird. This is a serious issue as I believe I have followed all the correct settings including in-line display, and yet for some reason, Thunderbird does not display the images.

Any suggestions are appreciated as I am baffled since Thunderbird has been my go-to email client for years.

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.

My wife & I have the same PCs running Windows 10 & Thunderbird 115.11.0 (32bit).

We have a hosted web-site that also supports email, and we each have an email account (eg neddy@goon.com.au & minnie@goon.com.au). I've checked that both our POP server configurations are identical but despite that about once a week minnie@goon.com.au receives a warning to add security exception but neddy doesn't. This started happening two weeks ago after a years error free running.

The host has checked that goon.com.au has a valid SSL certificate, so what could be causing the discrepancy and how do I set about fixing it please?

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…

I have Thunderbird 115.8.0 installed on my MacBook Pro with two email accounts, Yahoo and Gmail. I have set up the Tools/Message Filters/Block Filters as well. When I first launch Thunderbird all the spam shows up in my inbox, and just sits there. What I have to do is go to Tools/Message Filters at which point I'm asked to select an account. I select Yahoo (my primary account) and then "Run Filters" before anything actually happens. Then if I go back to my inbox, the spam emails start disappearing. It seems that Thunderbird does not remember the "Yahoo" selection in filters in between launches. Is there a setting I am missing, or is this just the product of having two different email accounts? Thank you.

I hope someone can help, I've changed all the settings in Thunderbird for my whole family's emails (hotmail.co.uk, hotmail.com, live.co.uk) from Normal Password to OAuth2. All incoming and outgoing servers are exactly the same as Microsoft advised. None of my accounts work, neither for sending or receiving.

I removed one account and tried to re-add it (that was the advice given if the first method didn't work) but when it tries to check the password, it takes forever. I've tried to manually configure it but it wouldn't download any folders or emails. I removed it and tried to re-add it but have been unable to do even that.

My default account hasn't been able to send more than 25% of emails for a few weeks. I'm up to date with all updates and I've restarted Thunderbird and my laptop countless times.

Can anyone point me in the right direction please?

Subject says it all . . . I installed 24.4.0 on a Windows 7 x64 system and followed the installation instructions to the letter . . . adding a single GMAIL email account with password.

After the install, I checked Options > Security > Passwords > Saved Passwords > Show Passwords to confirm the GMAIL email account password existed - and it did.

While the PC was powered on and I was at my Desktop, TB worked perfectly. But once I powered down or rebooted, TB no longer had the GMAIL email account password. To confirm this PROBLEM, I checked Options > Security > Passwords > Saved Passwords > Show Passwords to confirm the GMAIL email account password existed - and it did not - the entry that once appeared was now 100% gone - no entry existed.

Thinking the install was mucked up, I uninstalled TB (and Firefox), then rebooted - ran cleaners - manually searched for every occurrence of TB, FF and mozilla, and removed only the effected registry entries, also searched for every occurrence of TB, FF and mozilla on the HDD added during the install and removed them - then ran the registry scrubbers again.

Once I knew my PC was totally clean of any TB, FF and mozilla files, directories, etc, I ran Windows Update to ensure the system was up-to-date.

Installed FF, then TB 24.4.0 adding a single GMAIL email account with password - and while the PC was powered on and I was at my Desktop, TB worked perfectly. But once again, once I powered down or rebooted, TB no longer had the GMAIL email account password.

To confirm this PROBLEM, I checked Options > Security > Passwords > Saved Passwords > Show Passwords to confirm the GMAIL email account password existed - and it did not - the entry that once appeared was now 100% gone - no entry existed. According, the EXACT SAME PROBLEM REMAINS and I wasted my time uninstalling FF and TB, cleaning and scrubbing, etc.

I do not share my PC, it is a home PC and I am the only person using it - therefore I do not use a MASTER PASSWORD.

When will this EMAIL password problem be CORRECTED? Or, what is the fix?

Thanks,

CurlySue  :)

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!

I tried my current Hotmail pwd, but received: 'Login to Server imap.gmail.com failed'. 'Retry', 'Enter New Password' or 'Cancel'. I tried all 3 previous Hotmail pwds, but receive the same. I added a Master Password just now, but still get the above…. Help!!!

Thanks!

I deleted Thunderbird, than Installed latest version. Now in Thunderbird "Use Primary Password" is clicked so I can't reset primary P/W. Previous P/W doesn't work because there is no P/W there as far as I can see. Instructions I found: "Tools> Developer Tools> Error> etc. There is no "Error" button. Instead I get Incoming Connection (attachment) and an other screen that I don't understand. Can you help please? Thank you Ilio Pieroni

I have received an email from Microsoft informing me of changes to its authentification procedure. As from Sept, to continue using Thunderbird to access my outlook/hotmail accounts, I have to change the authentification method to Oauth2. The reasons and changes required are detailed here: https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202 I have 2 problems. 1. imap-mail.outlook.com - I can change my authentification method to Oauth2. However, when I then try to access my mail via TB, I get an error stating that the server imap-mail.outlook.com does not support the authentification method! (see image) 2. Outgoing Server SMTP There is no Oauth2 option available to choose!

Can anyone help? I am using the most up to date version of Thunderbird 115.12.2 (64-bit).

Hi Thunderbird Support Team,

I recently installed the latest version of Thunderbird in a Hyper-V virtual machine and encountered the following message: " Approval required Mozilla Thunderbird This app requires your admin's approval to: Read and write access to mailboxes via IMAP. Read and write access to mailboxes via POP.

Allows the app to have the same access to mailboxes as the signed-in user via POP protocol.

This is a permission requested to access your data in xx Send emails from mailboxes using SMTP AUTH. Maintain access to data you have given it access to View users' basic profile"

This was functioning with the previous version of Thunderbird, but now my IT team requires additional information about what the app is trying to do with our Office 365 environment. The approval process is crucial because some apps may introduce security risks or seek extensive access to our Office 365 resources.

Could you please provide more detailed information on the permissions requested and the specific changes in this version compared to previous versions? This will help in getting the necessary approval from our IT team.

Thank you for your assistance.

Best regards, Jenny

My Thunderbird Version: 115.12.2 (32 Bit)

Microsoft is changing the authentication method for outlook mail to OAuth2. I follow the guide here,

https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202

And I get to this screen - but my version of the program does not have OAuth2 as an option (see attached image).

Thanks for the help.

Dear Sir or Madam,

I have just migrated Thunderbird to my new CUBI desktop running Windows 11. I get security errors when I launch Thunderbird. My email provider The Messaging Company advised me to change server settings, which are now shown in the Troubleshooting Information page as account1 (pop3) pop.themessagingco.com.au:995 SSL/TLS Normal password smtp.themessagingco.com.au:587 STARTTLS Normal password true.

On launching Thunderbird I get the message Secure connection failed live.mozillamessaging.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate has expired. Error code: <a id="errorCode" title="SEC_ERROR_EXPIRED_ISSUER_CERTIFICATE">SEC_ERROR_EXPIRED_ISSUER_CERTIFICATE</a>

   This could be a problem with the server's configuration, or it could be someone trying to impersonate the server.
   If you have connected to this server successfully in the past, the error may be temporary, and you can try again later.

Or you can add an exception…

AND when I attempt to send an email I get warning that the SMTP server does not have a valid certificate. If I ask, in either case, to "Get Certificate" the response is that the site attempts to identify itself with invalid information.

I have "tried again later" over two weeks, and nothing has changed.

The Messaging Company is a fairly large email provider: it seems strange that its security is incomplete. However, I am not happy to just set an exception and over-ride these errors without doing all I can to check that there is not something screwy going on. I really value using Thunderbird, and The Messaging Company's advice that I should just use webmail is not at all satisfactory: I keep everything on my computer or backed up to a portable drive here.

Please: is there anything I can do or should know to fix this problem?

Best Regards, Margaret Mackisack

Thunderbird continues to block my outgoing emails despite my best efforts. Please check my outgoing smpt server settings (attached) and let me know what I need to change. Thanks.

I currently receive all messages sent to me including those from Comcast but I can't send messages to any email address. When I logon i get the message: Enter Credentials for my email address on imap,comcast.net. I read the document: Switch from POP to IMAP account > Create the IMAP account. I never saw the window shown on page 3 of the document. The other day I got a message that the IMAP account was already created. I then edited the my SMTP account.

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.

Cox recently required security changes. After I walked through the steps, the last thing was suppose to be a pop up window asking for my password. This never happened. Now when I try to download messages I get this. Cox support says thunderbird is the problem and directed me here.
