The Help says to alter several Thunderbird features to allow Outlook to communicate. The last one says to change my Outgoing Servers setting for Authentication Method to OAth from normal password. That option is not present in my drop-down list.

Thank you to David & Toad-Hall who kindly worked to get my Thunderbird to download my messages from Juno in a series of support messages in mid-July.

I have worked with KW, a computer help person at my senior center. I have a follow up appointment with KW on Fri 8/16, 1 pm MDT. Last session KW succeeded in re-setting the STMP server port to 25 and the POP3 server to 110. See screen shots.

This did NOT enable Tbird to download my messages from JUNO. There was a' change, Tbird would no longer SEND messages via my Juno account, earlier it would send test messages. see 3rd screen shot

Like Toad-Hall, KW is suspicious that the last message Tbird downloaded from Juno 6/26 that directed me to reset my password in Juno was malicious. We reset my password and Juno & Tbird both open with the new password I set up directly from the Juno webpage.

KW suggests I ask you if it is possible to deinstall & reinstall Tbird, Might that restore Tbird to function? Would I lose the contents of my saved messages in folders?

Additional screen shots, maybe useful info.

I really love my Thunderbird! I like to work off-line, I like storing my files on my computer computer.

I am viewing my emails, and I can see that some emails are not nesting properly. It doesn't happen all the time. I am expecting all emails in the thread to have the same subject. Please see screenshot.

Dear Sirs

I have really made a mistake in my settings. Unfortunately I have had difficulties reading my written mails and have tried several things. Changing the layout, using the zoom etc. TB does not save my settings and keeps writing af very small font. The font has always seem very small.

To search any help I have found the following: https://www.youtube.com/watch?v=klIOX4dsXU4&ab_channel=ChrisWaite

I really think I was very carefully about the change and I really do not know what has happend. I have somehow changed the default value in: layout.css.devPixelsPerPx from -1.0 to what was expected to be 1.20. But now it covers all my screen and I have no possibilities to find settings menu or even to move around to more menus.

I really appreciate if you can somehow help me to edit to the default value again. I can't find any config files in my PC under APP.data.

I really will feel very sad - if I cannot go back to my lovely mail clients settings and using all my setup in the future.

Please take a look in attached picture.

Hope you can Help - I will really feel very thankfull for your helping support.

Best Regards Alex

Every-time I open up Thunderbird E-mail, I get a pop-up box that says: log-in to account failed (see attached picture) A little information about my situation; I have used Thunderbird E-mail Program for years with my Hotmail Account, without any issues! I have also used "AVG Virus Protection" and I have Windows 10 Pro. My problem is every-time I open up Thunderbird E-mail, I get a pop-up box that says: log-in to account failed (see attached picture) This problem started long before I installed your latest "Thunderbird Version 128.0.1esr (64-bit)" to try and solve this problem, it doesn't matter what I click on, on that pop-up, it keeps reappearing and I can't get my e-mails! However.......I can log into my Hotmail account using "Firefox Browser" and I can get my e-mails, but I don't like their ads, where as with Thunderbird there are no ads! :-) How do I get your program to work again? I assume something changed, to make it not work, but I don't now what that would have been, do you? I have switched the Password settings to something I read here, in your help section, it did not work. (See picture of my server settings). NiceSeeingYou aka Keith

Hi, Nearly all of the User Interface windows on Thunderbird are tiny. For example, if I open the "About Thunderbird" the window is tiny. Likewise, various windows with instructions that come up are tiny. I have been able to at least read messages and read the settings windows by cranking up the font size but this does not help in general. This feels like a display resolution issue but other programs are fine. So if I change the system display res, I expect other programs to be huge. I have seen some threads on this in the archive but for older versions. I am running TB 128.1esr (I think - difficult to read!) on an iMac running Sonoma 14.6.1. I just upgraded to a new iMac and my previous installation was on Mojave and ran a thing called Theme and Font Changer, which is now disabled (possibly some buried consequence of running that add-on is resonspible). Really would appreciate help!!! Thank you. Tobias

I use thunderbird through vpn to my work site. I am required to use two accounts, one to login to thunderbird and download messages and a separate smtp password to send messages.

After logging into thunderbird, the first attempt to send a message works fine. It prompts me for my smtp account password and sends my message.

The second and subsequent times I try to send a message, I get the popup error:

``` The message could not be sent using Outgoing server (SMTP) relay.xxxx.xxx for an unknown reason. Please verify that your Outgoing server (SMTP) settings are correct and try again. ```

The thunderbird error console reports:

```

   mailnews.send: Sending failed; 
   The message could not be sent using Outgoing server (SMTP)
   relay.xxxx.xxx for an unknown reason. Please verify that
   your Outgoing server (SMTP) settings are correct and try
   again.

       onerror resource:///modules/SmtpService.jsm:211
       _onError resource:///modules/SmtpClient.jsm:510

``` Once I restart thunderbird, I can send a message again - exactly once.

Other mailer applications using vpn to connect to our mail system do not have this problem.

Thunderbird does not have this problem when I am connected directly to my site's internal network, not using vpn.

My thunderbird Outgoing Server configuration is:

``` Hostname smtp.xxxx.xxx Port 25 Username xxxxx@xxxx.xxx Authenticaton Method Normal password Connection Security STARTTLS ```

Those settings are consistent with my site's requirements.

I'm using thunderbird 115.12.2 on a mac running macOS Sonoma 14.5.

This problem first surfaced when I upgraded from thunderbird 102.12.0 to 15.4.1.

It really acts like things are configured okay, because it was able to send one message, but then something gets stuck after that.

Thanks for any insights.

It was barely noticable, but SERVER NAME in Server Settings was the same for both accounts. These were Yahoo IMAP accounts. Each account had its own folder in Users / ....... / ImapMail, but both accounts were pointing to one folder. Corrected this in the SERVER NAME field in Server Settings (see image)

"SHOULD" solve the issue .......... particulary it is THE ONLY item I can find that was not normal.

Hi. For the past few months I have been unable to play any samples from the Audible website in Firefox on my android phone. When I click the word "Sample" Audible opens up a new tab with their Web player and I always get an error message that is just a rectangular box with an exclamation mark inside a triangle on the left side of the box. (Screenshot attached.) There are no words inside the box and the only option is to close the tab. Since there is no actual message I'm not sure what the problem is.

Here's a link to the page visible in the screenshot: https://www.audible.co.uk/webplayer?asin=1445081911&contentDeliveryType=Unknown&isSample=true&ref_=a_pd_jpp_cloudplayer_1445081911&overrideLph=false&initialCPLaunch=true

Playing samples used to work fine when you could play them within their web page before Audible changed its system. I seem to be able to play samples on Audible's Web player in Chrome, but would prefer to keep Firefox as my default browser. I have tried deleting all history, cookies and cache; closing and reopening Firefox; turning phone off and starting again after an hour. I've also tried enabling autoplay, but that made no difference. I was thinking that the issue may be with my other settings within Firefox, but I can't tell. Any help you can provide would be great. Let me know if you need more info. Thank you!

(I'm in the UK. I don't know if that makes a difference, but I don't see a UK specific forum. Thanks.)

I recently tried moving the thunderbird profile folders to a different hard drive (D) as they were bloating up my boot drive (C). After unsuccessfully attempting to move them through thunderbird itself, I manually dragged them onto a different drive and attempted to import the settings via the import tool, to no avail. After restarting thunderbird, it reset itself completely and I had to log into all the emails tied to it again. It then proceeded to somehow redownload my profiles onto the original hard drive (C), but all the local files, despite being present in AppData/Roaming, are not present in thunderbird itself.

Any help recovering those local folders would be greatly appreciated.

Outlook sent me an email on 3rd July stating "Update your sign-in technology before September 16th, 2024 to maintain email access."

As of today, 23rd July 2024, I am unable to access my Outlook email account through Thunderbird as it repeatedly asks me for a new password. Is there any way to resolve this and continue receiving my Outlook. com emails through Thunderbird?.

I do not want to access my emails through the Outlook app.

Version of Thunderbird I am using is 115.13.0 (64-bit), on an M1 Macbook Pro running Mac OS Sonoma 14.5.

Thanks for your assistance.

I just got a new computer running windows 11 pro. I downloaded Thunderbird, which I used on my old computer(windows 11), and followed the steps to set up my email. I know my email address and password are correct as well as the server settings and I keep getting the following error "Unable to log in at server. Probably wrong configuration, username or password". My email is .verizon.net which is handled by AOL. My husband also uses Thunderbird and verizon email and I checked the configuration against his computer and everything matches. I was able to get my gmail account added so it must be something with aol or windows 11 pro. Any help is appreciated.

Dear all - I can't send email from Hotmail, and haven't been able to for several years now - I use the webapp, but i'd love to get Thunderbird working again...

I tried following the troubleshooting advice several times, including the most recent 2024 post, and still it won't work...

Here are my current settings, I think they're slightly different from the screenshot, but it still doesn't work!

I've checked my firewall and I don't think it's that.

I am using a VPN.

Thanks in advance, JG

For about two months, video quality has been persistently low for me on Youtube. Quality options are limited to 360p and I am unable to change it. Additionally, I am unable to play video on other platforms such as Vimeo, Pinterest and other streaming sites. Sites return errors such as 'Player is unable to play video at this time' or error code 102630. I have refreshed my cache and reinstalled Firefox and neither have resolved the issue. Notably, this issue does not occur on other browsers such as Chrome or Microsoft Edge. As far as I know my drivers are up to date and the Windows Media Feature Pack is installed, although it shouldn't be an issue seeing as sites work on other browsers. The issue also persists in troubleshooting mode. I've gone through the console and included images of some interesting errors that might be of use, although I don't have the technical knowledge to know what they mean. Please inform me if there is any other information I can provide that would help. Thank you!
