I am really really distraught right now. It took me two weeks to get the time and focus to write a long reply to a company's nice email to me. Stayed up till 2am to write it. Deliberately wanted to re-read it in the morning before sending. Gone. Nowhere to be found. I pressed "Save to draft" before closing my laptop. But not saved. This account actually has a "draft" folder, unlike most of my other accounts in Thunderbird, which I also cannot figure out and no one has helped me with.

Starting on 10/01/2024 Thunderbird no longer allows me to send or receive email.

When I try to read messages using Thunderbird, I get the following: Sending of password for user XX@msn.com did not succeed. Mail server outlook.office365.com responded: Logon failure: unknown user name or bad password.

When I try to send messages using Thunderbird, I get the following: Enter your password for XX on smtp.office365.com:

I have tried redoing the password and it does not help.

This is on a WIN/10 system. I updated to the latest version of Thunderbird and it did not help.

I checked out Thunderbird on my WIN/XP and get the same results as with WIN/10.

When I use Firefox and login to https://outlook.live.com/mail/0/, I can send and receive email as before. The same is also true with my Mobile Phone.

I'm having an issue with some of my filters not working. I've checked the several times and they should be set up correctly, but, for some reason, they don't perform their respective actions, even when I press "Run Now".

Also: I recently changed the sorting of my e-mails to be threaded by chain. I like to have all of my most recent e-mails show up at the top, but, within each thread, the most recent e-mail shows at the bottom (see the supposedly-attached image). Is there a way to flip this?

Thank you in advance.

I installed Thunderbird and typed in my Office 365 email information to connect my account. Thunderbird found the correct IMAP settings, which I verified on Microsoft's website. It proceeds to open a browser so I can authenticate my account. After that succeeds it starts downloading all of my messages & folders. I thought everything went fine until I attempted to send a message. I get the following error:

Login to server smtp.office365.com with username me@mydomain.com has failed.

It gives me the option to enter a new password, which doesn't make sense since it's oAuth2 but I created an app password to see if that would work, and it didn't. The only other options are cancel & retry which don't help either.

I thought maybe something went wrong with the authentication process so I uninstalled thunderbird and started again with the same results. I've tried many other server settings, but nothing works, so I'm here.

Current Settings:

Server Name: smtp.office365.com User Name: me@mydomain.com Authentication Method: oAuth2 Security: STARTTLS Port: 587

I've tried: Using Port 465 / SSL/TLS Using Port 465 / STARTLS Using Port 587 / SSL/TLS Changing Auth method to Normal Password and then using app-specific password. Uninstall / Resintsall

One final thing to note: I followed the same process with my fastmail.com account, which worked flawlessly. I can send & receive fine.

Hi

 I am using version 115.14.0 (64-bit) and I am using Fedora 39, up to date OS.  I have been using ThunderBird for a very long time.  I have been experiencing an issue which, unfortunately, seems to come and go.  I am experiencing this issue on 2 separate physical computers.  How can I restore the list of emails under any account when they are not visible?
 This is very troubling ...

Can anyone tell me how to set up the THUNDERBIRD TO ALWAYS LOG-IN into its own Messenger and avoid the Yahoo's interference with his INADEQUATE Messenger format - this should not be high-science question but I have difficulties to find an information in the HELP-section - thanks, Tony H. ...!

Hi there - been using Thunderbird for donkeys (since it was Eudora!). A few weeks back I started to get messages from Microsoft that I needed to change security settings as they were no longer supported on 3rd party email handlers like Thunderbird. So I re-created the three accounts I had there and it seemed to be OK, though SMTP did not have the OAUTH2 option available ... and when I tried to use the new SMTPs they wouldn't work. So I reverted to the old settings there and it worked again.

But this morning, with the big update to Thunderbird Nebula, I can no longer send emails from the MS accounts. My Gmail one is still OK ... but whatever I try, I cannot get the MS ones to send emails - I get a failure connecting.

Login to server smtp-mail.outlook.com with username xxxxx@hotmail.com failed.

I checked on MS and the details shown there:

SMTP server name smtp-mail.outlook.com SMTP port 587 SMTP encryption STARTTLS Authentication Method OAuth2/Modern Auth

Are what I have (I did have a different SMTP Server name came up - smtp.office365.com - but that doesn't work either)

So ... where is the issue? Is this a bug in the new Thunderbird setup? Something else? I don't know where to go ...

David

I changed my gmail account password, and Mozilla Thunderbird is losing its mind. I did the Oauth, logged in, but Thunderbird keeps popping up "Mozilla Thunderbird Email wants to access your Google Account" over and over again, even though I keep clicking on "Allow"!

I need to get my centurylink emails moved to thunderbird, ( and keep them in my centurylink for now also ) all folders and contacts if possible. NO IDEA how to start the process here after the initial account set up is done. Please , in easy to understand terms if possible, am computer challenged for the most part.

After update 138.0.1 my profile is not "opening" emails.

I can see that im getting emails, i can see that i can send and make new emails, but the emails when i either click or double click them are "white".

I even tried reading the "source code" it shows nothing. I even tried going to the beta channel, but no avail, the issue persists.

Is there a cleanup, any file to delete? something?

Good morning,

I cannot delete drafts in my draft folder. I have sent the emails, but they are still in the drafts folder.

Does anyone have a solution to this problem? I now have 22 emails in my drafts folder. When I delete them, they immediately re-appear.

TIA, Leslie

since 8/22/24 I have been unable to send email from one of my personal domains. Same install of T-Bird successfully sends SMTP via Gmail and my other domains.

I receive the error shown in the first photo below. Sending of the message failed. An error occurred while sending mail. Outgoing server (SMTP) error. The server responded: us2.outbound.mailhostbox.com ESMTP not accepting connections.

I have been back and forth with the domain tech support. Here are the email content (parsed for easy reading)

Me > I am having difficulty sending email. > I can POP email without issue. > I am using the most recent version of Thunderbird; version 128.2.0esr (64-bit) > When I send (with or without an attachment) I get the following error: error as shown above > I have never seen this error before and cannot find it in your knowledgebase files. > My SMTP settings: > > server name: smtp.drachenfelspress.com > Port: 587 > Connection security: None > Authentication method: Password; transmitted insecurely > User Name: mcaputo@drachenfelspress.com

Tech: If you are able to download emails from our server but unable to send out emails through the same, then it is likely that your Internet service provider is blocking port 25 on your local network. For such ISPs, you must use their SMTP server to send out mails on their network. Customer Support - TH

WELL Since I was using 587 that didn't help at all.

ME the error says YOUR server, "US2.outbound.mailhostbox.com ESMTP not accepting connections." This is YOUR error, not my ISP. I was using port 587, my ISP does not block port 25.

Tech try non-SSL using the following: STARTTLS Auth Normal change server name to smtp.<yourdomain>.com

Me No change

Tech Try reducing TLS version back to 1.0

Me No difference. Restored TLS 1.3

Tech return to the mailhostbox.com server Port 587 STARTTLS Normal full username

ME ok, no difference. That is where we started, didn't work then, doesn't work now. (second photo)

Tech Try port 25

ME Same results

Tech <resets my password>

Me Did you reset my password overnight?

Tech To investigate the issue, we needed to reset the password for mcaputo@drachenfelspress.com, to enable us to configure the Thunderbird email client on our end. The temporary password is "Se!!P)iqk2" We have successfully created a Thunderbird account and were able to send emails through it without any complications. The configurations we utilized are displayed in the screenshot provided below: us2.outbound.mailhostbox.com Port 587 STARTTLS Normal full username

Then change your password.

Me I appreciate your response. HOWEVER the issue remains.

Tech We have already replied to you on this matter.

ME Tried sending on port 465 and it indicated "sending" but hung there. Using Telnet I am able to access the us2.smtp.mailhostbox.com on port 587 but I cannot trigger an AUTH login through TELNET. (see CMD screenshot below)

Tech What is your IP address?

ME It is not static, but today's is (IP address at the time given)

Tech We have done further testing by setting the ThunderBird email client for mcaputo@drachenfelspress.com to both SSL and Non SSL connections. We can see both the implementations being fetched correctly without any issues. <provides two sets of POP and IMAP settings>

ME I can POP successfully, have always been able to. Problem is with SMTP, outbound mail.

Tech Provides two incomplete setting combinations: us2.smtp.mailboxhost.com port 587 smtp.drachenfelspress.com port 25 Upon using any of the two implementations, SSL or Non SSL as configured above, there should be no issues in setting up the email client.

The SMTP and IMAP passwords (if asked any) will be the same as your current email account password.

We are unable to replicate the issue you mentioned. Customer Support - TH

ME I am unable to replicate your success. I still cannot SEND email.

Tech We have rechecked and can confirm that we are able to setup the email client on the latest version of thunderbird i.e 128.2.1 as well using the same IMAP settings as shared in previous email. We are afraid that we are unable to replicate the issue you are reporting after numerous tests from our end. As a suggestion, could you try to connect to your mail account from a different network or ISP? Customer Support - TH

ME Again, IMAP is not used on this account the issue is with OUTGOING mail. Tried both SSL and non-SSL settings for drachenfelspress.com outgoing mail will not send.

That's ALL I have right now. I am going out right now to try to send email from a laptop with a fresh t-bird install while sitting in a McDonalds on their wifi...

Help?

Hi there David

Not sure I'd you will see this... I cannot tell you the steps I took as I followed the path but I now have no emails on my old laptop either... Everything is gone...

Thanks Sally

I use Thunderbird 128.2.0esr (64-bit) to read mail from the Outlook server; these are the folder mappings:

imap://<email>@outlook.office365.com/INBOX imap://<email>@outlook.office365.com/Sent imap://<email>@outlook.office365.com/Drafts imap://<email>@outlook.office365.com/Trash

I used to also be able to read the Junk Email folder from the Ourlook server the same way, but the folder disappeared from my Thunderbird a couple of months ago. I tried re-adding it as a sub-folder, which is how I created it in the first place, but it won't appear on the list.

I'm not sure what else to do here. I don't know where the Thunderbird directories are stored locally any more, I'm using Ubintu 24.04.

I use Thunderbird on Windows 10; I have a verizon.net email account which I access through Thunderbird. Verizon.net email is transferred to the server from AOL Mail, and I have been able to get and send my emails on Thunderbird at verizon.net for years. This week, after Thunderbird's latest update, I have not received any incoming mail on Thunderbird, but I can see my emails on AOL Mail. The technical expert I consulted deduced that the problem is with Thunderbird such that AOL is not connecting to the incoming mail server, even after the password was changed. I can send messages successfully from Thunderbird; the outgoing mail works.

Oh, woe is me. I had both Thunderbird and Firefox open on my desktop, and thought I was typing into Firefox's address bar. But Thunderbird was actually 'live' (selected?) on the desktop, so that's where my keystrokes went. Not sure what I typed or where the cursor was, but suddenly I have two folders in the left Thunderbird pane that I can't figure out how to get rid of. They are both just above my Local Folders: Templates and Archives folders for one email account, and an Archives for another. All three folders are empty (Archives had "2025" subfolders, but I was able to delete those). Keyboard strokes generated these, but they don't delete. What can I do? Can I navigate with Windows Explorer to where these folders actually reside and delete them there? I sure don't want to mess anything up. Many thanks in advance!

Bonjour, récemment j'ai dû reinitialiser windows 11, j'avais fait un backup avec ashampoo backup. Après reinstallation de thunderbird, je voudrais restaurer le donnés et surtout les archives. J'ai restauré les données dans de profile, mais je ne vois pas les anciens messages ,calenders et contacts. J'ai lus dans les forums , de recharger la version 141, pas de succès. J'ai lu aussi d'effacer global-message-db.sqlite , pas de succés. Que doit je restaurer, et dans quel version ? Merci pour votre aide. André
