Dear Team After Updating from 102.15.1 (32Bit) to 115.28.0 (32Bit) I can not connect to the provider "pop.hispeed.ch" anymore. Ping pop.hispeed.ch (on CMD) shows normal raction of beeing reachable with a "reply from xxxx.". I am on Windows 7 SP1. I have checked several times all setting POP and SMTP, switched off Firewall, uninstalled virus scanner, and and and many more (all knowledge found on internet..). Pressing the "Get Message" button in the upper menue bar shows no raction when pressed. The icon "Get Message" on the left side of the button "+ New Message" results in a none moving blue status bar at the right bottom of the window. After a while with the message "timed out.. ".In the settings "Config Editor.." the values of "mailnews.tcptimeout" are set to "300", and "true". I am using TB since donkey years with many many eMails. Are the lost? Thank you for support and help, Andy

A search showed that others have experienced this same error message, but as far as I can tell, they all were unable to access their email. These messages began appearing about a month ago. They pop up in Troubleshooting Mode. They did not in Windows Safe Mode. AVG and ZoneAlarm are not the culprits.

Hi All, I have been sending emails through Android Thunderbird, but they aren't being synced to the server, so I can't see them anywhere else. I've set the Sent folder to sync (as well as the Inbox). Pressing the sync button just spins the indicator, but doesn't actually sync. When I try to move or copy messages, an error comes up saying that messages can't be copied or moved that aren't synconised. How can all my messages (sent, inbox, everything) be synced so that I can see them everywhere? I've just turned on sync debugging, will see the results soon.

Every time I open thunderbird I get a blank screen with this message, 'Edge: Too many requests' over the top of the thunderbird screen. This screen stays on my desktop after I close Thunderbird and I have to change my screen resolution in order to close the screen. Can you help please? Martyn Smith

One of my two outlook email accounts no longer appears in Thunderbird, which says it is authenticated but not connected. This happened suddenly. I can still get the messages by going onto outlook.com. How do I get it back on Thunderbird?

Thunderbird, quite suddenly, stopped getting my email; Both on my account and my wife's account at the same ISP. I spent more than two hours on the phone with the ISPs help line trying to resolve this issue. They also use Thunderbird at their help desk, and the agent I talked to was familiar with your program. She (the agent) was not able to replicate the issue on their system. We then tried to set up a NEW email account. I carefully entered all the info needed for a new account, following instructions from the agent, then hit the 'Test' button. I got the following message onscreen: "THUNDERBIRD FAILED TO FIND SETTINGS FOR YOUR EMAIL ACCOUNT" The answer to the original issue suddenly became very clear - Thunderbird cannot, or refuses to, connect with the email server, therefore NO EMAIL. We tried everything in her toolkit to resolve the problem to no avail. We finally tried UNINSTALLING Thunderbird (and the Maintaince program). Once Uninstalled, I used the Registry Tool on CCleaner to remove any entries in the registry referring to Thunderbird (there were several), then restarted my computer. I then downloaded and installed a totally NEW Thunderbird program. When I ran the Thunderbird again, I found all my account(s) info was still present, and Thunderbird was still unable to find the server. I'm at my wits end trying to resolve this issue, and REALLY HATE to go back to Microsoft OUTLOOK to get my email. Anybody got any ideas??? Any help would be greatly appreciated. (Signed) Proteus

Hi, T/bird working fine upto Thurs night Feb 26th then yesterday morning I got pop up windows asking for login credentials. Nothing had changed. Tried logging in thru them put it errored: <<

               Something went wrong

We could not sign you in. Try again from a different device. >>

I can log into my Yahoo accounts using Firefox so passwords isn't the issue

I've read thru a number of threads on here and elsewhere but no solution so far. K9 is working on my Android phone and my wife's and her T/bird is working on her PC. Just checked versions, she is on 140.8 ESR and I'm on 148.0. Both running Win 11 Pro.

Tried changing from OAuth2 to Normal, pop window asking for password but that doesn't work

Seems to me to be an issue with Ver 148.0 as my wife's working

What am I missing?

Thunderbird Version 140.7.1esr, Build ID 20260123195141 User Agent Mozilla/5.0 (X11; Linux x86_64; rv:140.0) Gecko/20100101 OS Linux 6.1.0-33-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.133-1 (2025-04-10) OS Theme Xfce / Adwaita Application Binary /usr/lib/thunderbird/thunderbird-bin

Having a problem with an ATT POP account. TB stopped getting mail. After a minute and a half or so (wish it would time-out faster), I get a pop-up box in the top right of the screen that states: "Connection to server inbound.att.net timed out" and then quickly goes away.

Deleted passwords and cannot see where to create them again, as it never prompts me for new ones.

Thanks.

So there was a problem with AOL today and I'm using Thunderbird for my Verizon account now AOL is back up and running but on my computer Thunderbird will not let me log in to The Host keep saying it's failing?

got a new PC, trying to add my email accounts to thunderbird. everything is working except for my hotmail account. I have tried reinstalling, changing settings etc. I removed my account from thunderbird on the old PC tried adding it to the new pc and I just keep getting this error "Exchange auth error" I cannot change the 02uthentic type as i cant add the outlook account. I have no problems adding it back to the thunderbird on the old pc. I have changed my password 4 times thinking it was the problem but nothing. this is what i get everytime.

I have signed into the web and made sure the "imap is on to allow other apps, programs etc" still get nothing. I downloaded the thunderbird app to my phone to try and i have no problem adding my hotmail account. it's only on this new pc with thunderbird, both tunderbirds are the same build# 140.2.0 on both new and old pc.

any help would be awesome, thank you

I have had an ongoing problem with Thunderbird being unable to log into the various mail servers that I use. I've tried repeatedly to solve this problem and have been able to cure it in the past by clearing the cache, but it recurs over and over again. I cannot keep wasting my time like this. I'm an independent contractor and I need to be able to use my e-mail client consistently. I've got work to do! This morning, it's suddenly decided that it cannot log into any of the three services that I use.

Is there a lasting solution to this problem? If not, please tell me and I'll move on peacefully, but please don't keep me chasing my tail for something that cannot be fixed.

Since an update 4-5 days ago, Comcast SMTP server does not accept login from Thunderbird. Comcast help page said it was updating and requires a more secure SSL security. Today the Pop3 server does not allow signin either.

How can I select a more secure encryption that will be compatible with comcast.

Thank you.

I occasionally have problems with Thunderbird insisting that posts in my frequently visited newsgroup are expired when they are not. Previouly, I've been able to resolve this problem by simply unsubscribing from the newsgroup and then subscribing again. But today, when I tried that technique, Thunderbird told me that there were no messages at all in my newsgroup. This is flat-out wrong because the newsgroup is quite active. Right-clicking and choosing Get Messages did NOT change the situation.

Then, to add an extra layer of aggravation, I added a second newsgroup to my subscriptions, one for Thunderbird itself, but it was empty. I deleted that folder and then unsubscribed to my other newsgroup and tried to subscribe again but now the "Manage subscriptions" button shows me no newsgroups whatsoever!

I am beyond frustrated by this nonsense. What do I need to do to get "Manage subscriptions" to show me the thousands of newsgroups that exist and how do I make "Get messages" to show me the messages currently on my newsgroup?

I'm using Eternal September to access Usenet. My operating system is Windows 10. The version of Thunderbird I'm using is 128.8.1esr (32-bit).

I have tried many times to get Thunderbird to connect to my Gmail account. Whatever I do, it always ends by saying "Unable to log in at server. Probably wrong configuration, username or password. I have followed all the instructions I can find. The Thunderbird release is 140.4.0esr (64-bit) Running Windows 10.

I have set up an "app password" in Google. Config in Tbird set to IMAP.

Any help will be appreciated. Thanks

I've recently set up Thunderbird on Linux Mint 22.2 and was unable to sign into Yahoo so I tried to sign in with Firefox instead and had the same errors :-

   Something went wrong
   We could not sign you in. Try again from a different device.

OR

   We couldn’t sign you in
   Change your browser settings to continue. Try the following:
   Turn off ad blockers
   Enable JavaScript

If you still can’t sign in, try a different device.

I can sign in with Chrome without any problems on the same workstation. Firefox version :- 147.0.4 (64-bit)

   Only Extension is Privacy Badger, but this is disabled for Yahoo.com

Thunderbird version :- 148.0 (64-bit)

   No extensions - as installed from Thunderbird download site

I'm not having any issues signing into any other websites / email accounts (Google, Hotmail).

I notice on the support website :- https://support.mozilla.org/en-US/kb/thunderbird-and-yahoo it says "Starting with version 148, Thunderbird is switching to a more secure authorization protocol PKCE for Yahoo" BUT this isn't offered in the list of Authentication methods, has PKCE been delayed? Currently using OAuth2 for Thunderbird

Hello, I want to convert my POP account to an IMAP account. I am following the procedure for creating a new email account. I enter the account name, email address, and password. But at the end, I always get the following message: Authentication error. Unable to connect to the server. The configuration, username, or password are probably incorrect.

Please note that I am using the same name, email address, and password as for my POP account, as recommended in the online help.

Best regards Dominique Chevalier

why does firefox blocks incoming http conection to localhost:8080 when I try to obtain a google oauth2 token using oauth2.py ?. The Google server returns the token via http to loaclhost:8080 and the port is blocked by firefox.

For 3 days now I have been unable to connect thunderbird to microsoft outlook. I have all the latest settings checked online with microsoft and it keeps failing... any suggestions on how to overcome this? Thanks
