I've been using Thunderbird for years to access my gmail account through my ieee alias. Sometime after 4/2/2025 my login fails with the message "Login to server imap.googlemail.com....failed". I've tried changing the imap server to "imap.gmail.com" but get similar results. For some reason, it appears that something changed on 4/3 that prevents a successful login to the gmail server from Tbird. I have both Tbird and gmail configured for OAuth2. Update: As it turns out, following the steps in this link resolves the issue: https://support.mozilla.org/en-US/questions/1375558

I know little to nothing about computers. My Mozilla account says it is disconnected whenever I come online. I do not manually disconnect ever. Keeps telling me that it cannot detect proxy even though my proxies are set to off.

Unable to send emails. A message appears saying the outgoing server (SMIP) smtp.gmail.com timed out. Try again. This keeps repeating. What can I do?

I ask the following question a WEEK ago. No one has offered a solution. Can someone put me in touch with Thunderbird Tech Support?

Recap

Thunderbird(TB) gets mail from Hotmail, my own domain, and gmail. I've use and auto-updated this program for the past 20 years. This is the first major problem I've had. Nothing has changed, ie: updates, new programs, or the like.

TB has stopped retrieving new mail since 05.12.2025. I can send mail but not receive mail. ALL settings are correct. I can go to the original sites individually and all the mail is there. Obviously I can send and receive mail on those sites, but TB will only send mail not receive it. The only thing I have not done is uninstall/reinstall.

Does anyone have any suggestions?

New Info: No error messages, sometimes when I click on "inbox" it says "Loading Messages" but it says that FOREVER.

Second question: If I re-install, can I bring all my setup, filters, and boxes to the new install without having to recreate everything from scratch. I have at least 100 subfolders and as many filters.

Each time I attempt to login w/ T-Bird, google mail gives me this message:

400. That’s an error.

The server cannot process the request because it is malformed. It should not be retried. That’s all we know.

my isp no longer supports Thunderbird. When I try to log onto my thunderbird account it won't let me connect to the server. I can check my email by logging on to their website and using their email program, but I would like to keep Thunderbird. I have been using it for year. Is there a way I can get their server to recognize thunderbird when I try and log on to it. The ISP is Breezeline....thanks

When I click on Firefox and the to my email it says there is a problem with my internet. My internet is up and running fine. I have done everything it says Firefox can't connect to the server at mail.yahoo.com.

When i receive email with linkages i am getting this reply when link is used

Afterward no mail is being received from any of the providers, everything is stopped at last time I connected before the error, i.e. 7/9/2026

What settings do you suggest to allow access to my att email account? I am using Thunderbird V 140.0.1 esr on an iMAC running iOS 10.15.7. The attached screenshots show the results of attempts to re-establish the account and the resulting error messages. It appears that the server settings need tweaking, since the user name and password are those I use to log in successfully to the att account with both Firefox and my iPhone. Thank you, Vince K.

I've been using the Thunderbird App (v12.1) on a Google Pixel 8 (Android 16) for a while now with several Email accounts from different providers. One of them is a T-Online Email address. Recently it appears to have stopped syncing the folders only for this account. I still get emails in the inbox but all the folders are empty. It only says "Bis zu 100 weitere abrufen" (request up to 100 more) but tapping that doesn't make a difference. In the settings I have the sync set to everything without limitation.

I tested the same account with K9 (v11.1) and Google Mail and in both all the folders have their content.

Does anyone have the same issue or any suggestions? Is there any logging that I turn on to see if there's any errors?

Thanks!

I moved to a new computer and successfully transferred my gmail account by moving the old profile to the new computer. But Yahoo would not connect.

I checked the setup: servers, ports and security. Using oAuth2. I deleted cookies and tried everything again.

Then I deleted the yahoo account (transferred when I moved my Thunderbird profile to my new computer). Now I can’t add it back. I have tried both imap and pop. Nothing works.

I have no problem logging in with the yahoo phone app, or Firefox. I have tried inputting a yahoo generated app password on both the new account setup and on the yahoo popup.

Yahoo account setup is looping, or hanging on the “checking password…” stage.

Since we needed to upgrade 2 PCs to Windows 11 (1x Pro & 1x Home) nothing works anymore with Thunderbird. It has MASSIVE and unsolvable problems to connect to our Gmail account via OAuth, Not only will it ask every single time again and over again to allow the connection, but moreover even after granting access it still can NOT send (SMTP) or save or even receive (IMAP) emails. It is maga frustrating and I am currently after days and days spend to unsuccessful fix the problem are at the point to looks for a more reliable alternative (if there is any). Just as background: Our Gmail account is about 14GB big, the local Thunderbird folder around 100GB; so yes it's big, but that's another problem, there are no easy or straightforward off-line archivers any longer to effectively and still easy accessible reduce the local archive.

I have set up Push Notification and have a small blue icon at the top left of the screen and I will get notifications but then I notice it has gone quiet and the little icon has disappeared so I have to close Thunderbird and then restart it to get the icon back at the top of the screen. Any suggestions please as to what is causing this.

Hi, I cannot any more access Yahoo webmail using Thunderbird (140.3.0esr (aarch64) on Mac laptop (Ventura 13.3.1 OS). When I tried to login directly into the webmail server via Firefox to clean the spam folder I was asked to change my password which I did and that works fine. I could change the password on iPhone Mail by first deleting and then making a new Yahoo account with the new email and that works too. I changed the password in Thunderbird following the web advice for two hosts found in the menu: mailbox://pop.mail.yahoo.com and oauth://login.yahoo.com (mail-w) - which one should be kept? After that, when I tried to get messages the following info appeared: "Host contacted, sending login information..." but the contact was not established. First, I use POP3 protocol for Thunderbird and, I believe, IMAP for iPhone Mail. Second, a brief web search suggested that similar problems occurred in Thunderbird before so I hope it will be relatively easy to solve this problem. Thank you.
