Thunderbird Support Forum

Hi,

I have a Mozilla Thunderbird email client, which has been linked to my Microsoft Outlook account using IMAP for years, and has operated perfectly well for my personal preferences.

At some point overnight (26th / 27th May) this stopped working and I am now presented with the error message "Sending of password for user xxx@xxxxxxx.co.uk did not succeed. Mail server outlook.office365.com responded: Logon failure: unknown user name or bad password" when trying to download mail.

This is very strange as I can log in directly to my Outlook account using the same user name and password. No settings were changed by me in either Mozilla or Outlook.

For information, I can still send messages from Thunderbird but not now receive them.

Can anyone help, please?

Many thanks.

All the posts suggest

 Please see https://www.mozilla.org/en-US/thunderbird/all/

but that just offers the latest version (current 91.9.1) which won't run on El Capitan.

Other posts tell you to look at

 https://www.thunderbird.net/en-US/thunderbird/releases/

but that only gives you the release notes for the older versions, without any download links.

How do you get the older versions?

Hi, I have an existing installation of Thunderbird 91.9.1 on my linux system. I have a gmail, outlook and web.de mail each running via this installation (IMAP). My new workmail is hosted by 1&1(ionos). I can log in via web interface. Autoconfig finds the configuration that is (according to their help articles) the correct one to access the Mail via IMAP. Incoming: imap.1und1.de SSL/TLS 993 Outgoing: smtp.1und1.de STARTTLS 587 normal Password Username is my full email address. There have been no typos. I checked 5x, copy pasted, rechecked. Pasted it into the web interface login, and thunderbird before clicking go on each -> tb - no, web - yes domain is talsen.team

I would appreciate some pointers to get this fixed. And yes i did read prior questions regarding this error. It did not help in my case.

I made a huge mistake, I was trying to make Thunderbird view larger, now it's much to large to be functional or to make changes or go back to original settings. Here's what happened.

I went into "advanced settings" and changed layout.css.dev.Pixels.Per.Px the size is to large and now I can not view or make changes to Thunderbird. I tried deleting Thunderbird and re-installing it but no luck, the re-install has same large scale issue.

Thunderbird used to ask me for my password on incoming emails but this has now disappeared and mail is automatically downloaded when I open Thunderbird. How do I re-instate this? I have version 91.10.0 on a Mac and have a POP3 account. I am still asked to enter a password for sending mail and would like to keep this feature.

In my thunderbird program, version 91 64bit, on linux mint 20.3 cinnamon, the region and date/time is displaying properly, but the TBird program is taking the number for the hour from the message time and putting that number into the date as the month of the message. So, a 55-01-2022 message was received in 06-01-2022 at 23:55:12, but the date should be 06-01-2022. What am I doing wrong?

My Thunderbird email program no longer accepts my password for my Gmail account. It's the same password I use to log on to Firefox and I can open my Gmail from there so I know it's the right one. I've tried deleting the password from the save passwords window and I've made sure that I've updated to the latest Thunderbird version and I've restarted my computer after all of the previous things. I'm out of ideas. Help?

Just installed an upgrade to Tbird, and the Cardbook integration fails, in that you can no longer put in a search. The search area is greyed out.

Can scroll to record but not search

It was working jyst before the upgrade and not afterwards

I have a profile containing three email accounts. It's huuuuge, but I was able to transfer it over to a second computer last year. I'd now like to update specific mailboxes on that second computer but don't want to have to recopy the profile.

Is there a way to update/backup/copy a specific mailbox for transfer to a second computer without having to use the profile?

Also, I'd like to be able to backup one of the three email accounts specifically. Is there a way to do this without using the profile? Thank you for any help.

More a suggestion than a question.

I had problem to change my "sound", but finally installed a .wma sound and it works fine.

Now a suggestion: change the menu to change the sound with only a .wav sound, instead of the current BIG list. For the fun, I found the http:\\www.soundrangers.com who produced sound of the background themes installed from Windows. It's still open.

I just noticed TB now has 5 address books & this is what I want to do: My email addresses are all mixed up so:

1] I would like down load all address books to 1 CSV file to sort & eliminate any email addresses that are NOT MY PERSONAL ADDRESSES.

2] Then I want to import MY PERSONAL ADDRESSES back to TB to 1 PERSONAL ADDRESS book, While eliminating [DELETING] all other PHONE BOOKS as I don't need them. I will do my own adding of emails myself, it's that simple.

Google has disabled POP access in Thunderbird. Specifically they have removed the option to allow "Less Secure Apps" from downloading emails using POP access. They define "Less Secure" as apps requiring only a username and password. Currently (as of June 2022) Thunderbird can not download Gmail emails using POP.

Just FYI I will gladly give up Gmail and keep Thunderbird. I believe the only workaround is to have Gmail forward all emails to another, more friendly, email provider until I am able to convert all my contacts.

Thanks!

Login to my Thunderbird account has failed for the second time in less than a month. The first time it happened, the system seems to have fixed itself. This time, it is locked. See the attachment showing the error message. I vaguely remember being advised a few years ago to delete something in my TB and reinstall, that the content of my account is stored elsewhere and would reinstall. Is that correct?

Hello. My Thunderbird Portable 91.10.0 (32-bit, Win7 64-bit) stopped working with gmail. Cookies are allowed in the settings. The latest updates are installed. What should I do?
