I have been using Thunderbird for ages now with no problem, but I suddenly realised that no recent emails were appearing from my Gmail account. I have tried everything suggested on line to resolve the problem, including uninstalling and reinstalling Thunderbird, and deleting and re-entering my acccount details but neither the IMAP or SMTP servers will connect to Gmail. I have reset all of the server settings on Thunderbird, and have checked that Gmail is IMAP compliant (which, apparently, is is now automatically). I have spent hours trying to sort this out and am just at the point of abandoning Thunderbird completely, but I am loathe to do so if there is a solution. The latest error message i have received is "Unable to log in at server. Probably wrong configuration, username or password" but I don't know what else I can check or change.

Accessing my yahoo email with Thunderbird have worked fine for several months. Now I cannot log in. Yahoo mail is not accessible from the web either. But the web login works fine from Windows. I tried to change authentication method from OAuth2 to password but that didn't help. When I start Thunderbird there is either a dialogue which requires password or a window (see added picture) with a long string at the top of the window. That string cannot be edited. The rest of the window is empty.

re: OAuth2 Authentication for Yahoo, AOL and ATT

My settings selections don't really follow your help descriptions to the letter,so..., also, I already have 2 accounts on 2 platforms and they seem to already be configured with SMTP outging servers using OAuth2.

I'm confused since I'm now on 140.8.0 and have not needed to change a thing, contrary to expectations set from T-bird app popup warning and Mozilla article.(?)

Hello! The other day everything worked as usual, and I shut down the computer for the night. The next morning, Thunderbird immediately crashed/shut down when starting each of the 2 profiles I always use. The 3rd profile, which is the default-release running a different email, still seems to work normally. Thunderbird 115.10.1

I have tried Windows (10) safe mode, as well as thunderbird Troubleshoot mode and working offline, but the issue continued to occur.

I'm at a loss now as to what could cause 2 profiles to suddenly cause it to crash. By the way, one profile is for a gmail account and the other one is for an Outlook account, so they don't seem to be related.

In case it helps, there were 2 Microsoft Visual C++ programs installed or updated, and updates to Microsoft 365 and Google Drive just before the problem started. These were all auto updates in the background.

Any help from the Community would be greatly appreciated. Thank you!

And the most annoying thing is that after this error, downloading other letters stops and you have to manually search for that very letter, although there may be thousands of them... Please fix this!

I have been using Mozilla Thunderbird for decades and they have even contributed a small amount of money to Thunderbird periodically. Just within the last two or three days all of a sudden I have been unable to send emails with my phone. I receive emails, but I do not send them.

So I opened up a laptop where I did not have Thunderbird and set it up properly through Spectrum using the incoming and outgoing servers as mail.twc.com. and yes, just like on my phone. I continue to receive new emails, but even with the laptop I was unable to send an email.

I received the message"send message error sending a message failed. The message could not be sent because the connection to outgoing server smtp mail.twc.com was lost in the middle of the transaction. Try again."

I contacted Spectrum twice and both times they had me try to send a message through their Web server spectrum.net and that message did go through. Of course then their response is that this has to be a problem with the third-party app meaning Mozilla Thunderbird, and they can’t help with that at all. I sure would appreciate some help because I hate to walk away from Thunderbird as well as change my email address after all of these decades.

I already have two Exchange email accounts using Exquilla that were created in earlier T-bird versions, they work in the latest version as well. I am trying to add a third exchange account, I enter the email and password do auto discover and get the following error; Invalid or missing password: password does not exist in the directory for this user. Trace ID: b2766d8c-6b02-4879-ab77-e30177281600 Correlation ID: 220ef2bd-c4b2-42a9-9414-d4f7bc0dae35 Timestamp: 2026-03-06 02:43:34Z

An Autodiscover site was found, but we could not find a usable entry. This is probably because your server does not support Exchange Web Services (EWS). If your server does not support EWS, then ExQuilla will not work for you. If you believe this to be in error, try manually entering the EWS URL.

I know the message is wrong since I have two accounts that function. I have gone through the manual configuration as indicated online and still have no success just says "URL test failed". I was hoping this latest version would have another way to be able to enter information to get around the failure. Any guidance is greatly appreciated.

Thunderbird has been working OK. Now, despite PC restarts and so on I get the message "mail couldn't be sent, time out error for SMTP server. I have tried changing the SMTP settings from port 465 to port 587 but no difference. If I log in to my email provider (vodafon/uniymail) I can send mails no problem. The problem is with thunderbird not sending smtp. Tried turning firewall and antivirus off, no help. Internet connection is glassfibre, internet works OK.

Empfangen von E-Mails hat funktioniert nur beim Senden oder Weiterleiten kommt die Fehlermeldung.

es Spielt auch keine Rolle von welchem Konto ich Mails verfasse, ob T-online,Web oder Agenturserver

Benutze den Acount auch auf einem Laptop mit W11, dort funktioniert alles,

Die SMTP Einstellungen hab ich überprüft, Laptop und diesem PC sind identisch (Hatte ja auch keine Änderung in diesem Bereich durchgeführt)

In our organization we have moved from an on-premise mail server to M365. We've also added our new EWS-based accounts to Thunderbird. Since there are a large number of users with a significant amount of older mails they want to have access to, they have been asking how they could upload them to EWS now.

From the looks of it, using TB one can either drag and drop messages from the local folders to EWS. Would message copy/move from the local folders be faster if the EWS account was setup over IMAP, instead of over EWS? If so, we could setup another account corresponding to the same EWS identity, but over IMAP, just for the purposes of transferring messages faster.

Thanks in advance for any information provided.
