I cannot access my email on my computer or send out email since the latest update. I seem to be offline. Is it because my operating system old? Please tell me what I need to know to fix this problem. Thank you for your assistance.

Hi, I used Thunderbird on a portable computer in installing automatically my mailboxes without issue. Then the systems suggested me to upgrade to Windows 11. I did.

But since that time I can not more use Thunderbird because it cannot set up my mailboxes on outlook and a specific national operator.

Is there an issiue in usign Thunderbord under Windows 11 ?

Tks.

So I have a self hosted Exchange and I have no problems using it from apps like Google Mail, Outlook and such, plus I can login directly to its .../EWS/Exchange.asmx through a browser. However, when trying with Thunderbird 145/Linux, I always get that username or password are incorrect, but it doesn't tell me exactly what went wrong and how it tried, so I'm in the dark why it is happening. Note: exchange's url is on a different domain than my account.

Basically it's either this message: Authentication error.

Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIMsgAccountManager.createIncomingServer]

Or similar if I try to get message from inbox.

Also weird things happen during configuration, like attached image (note that I've tried different URL permutations)

TLDR; how do I diagnose the issue, or ever better, how to connect? TIA

I have been using Thunderbird for months on my new computer. Last night when I brought it up, a new screen said "Unable to Connect" followed by good information like check the network connection, firewall, etc., make sure Thunderbird is permitted to access the web. Plus, the PC bubble communicated "Authentication failure when trying to connect to server imap.comcast.net".

I have checked everything (looked around) and all seems fine. However, I am a "senior" and maybe I missed some communication along the way. I am getting emails on my iPhone and on the Xfinity website, but Thunderbird is not connecting to the server now. Do I need to change any settings?

Until last month, Thunderbird never had any issue connecting to GMAIL accounts to send and receive messages. Suddenly, there is a bug and Thunderbird is not sending or receiving emails from GMAIL. Is anyone else experiencing this? Also, with the current version of Thunderbird, there is no way to insure that I am receiving updates and have the most current version. I have used Thunderbird for decades and it is now very buggy, and getting more difficult to use! - Mark Robbins

OK, so I have 4 different emails on my Thunderbird account. I get the most email from my usa.net (Netaddress.com) account, but that has never been an issue -- as my inbox gets huge I just move the contents into a dated archive.

I have already looped back to the people at usa.net and all of my settings are correct.

Here is the issue: Out of nowhere, a few months ago, when I tried to download my USA.net email, it would stop after 100-200 emails. Also, it would NOT "register back" to USA.net and show the downloaded items as "gone" (I checked my settings; I am NOT leaving email on the USA.net server).

I even tried deleting a ton of emails on the USA.net server side via webmail, and it still just stops after 200 messages max. I then need to dump out what was downloaded to another folder or I get the error below (see upload).

I hadn't changed anything on my settings when this started. USA.net DID start a requirement several months ago RE using SSL, but I didn't have problems when I initially made the switch.

Help, please! When it stops downloading I either get no message, or I sometimes get the message shown.

How to fix please? Again, this is the ONLY email account that I have this problem with; if some kind of "limit" was being hit it wouldn't be letting me download from other accounts, including my "business" email (basically I use USA.net for all of my newsletters, online purchases, etc).

Thanks so much.

Ok I know this has been asked before but I can't find a way to fix this. When I click on ANY link in an email or even the menus, not even the help menu works, I get a "no app associated" error. My file associations for .htm, .html, http, https are all set in the default apps in windows. I can click on an email address and it works just not any other type link. This is in version 144.

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.

I have been using Thunderbird for many years. I have 4 accounts that have all been set up and working fine. This morning the 2 yahoo.com accounts stopped working. I logged in to the impacted accounts using a web browser and password just fine. I then updated Thunderbird to 116.0 to see if that would fix the problem, but it did not. The outlook and gmail accounts are working fine, for now.

When Thunderbird attempts to download mail for the yahoo accounts, I get a large pop-up window with "Edge: Too Many Requests". The pop-up window is blank except for that error message. I get the small pop-up with the Authentication Failure message. Sometimes I get Retry, Enter Password or Cancel. But I never see a window that will allow me to enter my password.

I can send/receive mail from the accounts while logged in via a browser but authentication fails within Thunderbird.

I'm running Thunderbird with one account without problems. When I try to add a second account I get as far as entering name and e-mail. After this, a cirkle starts spinning and never ends.

Hi...I'm having trouble with T-Bird connecting to outlook.live....error message:

"Your browser is currently set to block cookies"

I checked my settings and I don't see anything blocked...I also added:

Microsoft.com Allow outlook.live Allow

...and I still get the same message - "set to block cookies".

I'm far from being a computer wiz and just started using T-Bird about a month ago and I'm very happy with it. Any help with resolving this problem would be great! It might be something simple...as I'm no expert and still learning. Thanks, Bill

Under Inbox | Trash in my TBird account is a structure

2019
  subfoldername
     sub-subfoldername

in italics, in gray letters. When I try to delete it, I see "The server replied [Nonexistent]" and the structure disappears; until I close and reopen TBird, and there it is again. When I select "Empty trash" I get no error message and the structure disappears; but it reappears on reopening TBird. How can I make it gone gone gone?

Ubuntu 24.04.3 LTS new installation. Thunderbird 140.3.1esr (64-bit) Adding an existing account Type in My name and email address and click Continue It says it is looking up configuration and it is just looping around and does not report an error. I have waited over an hour with no result. The only way to recover is to go to the taskbar and right click Quit. It would be helpful if there were away to know what is blocking the search for the configuration.

Trying to add an email account. I go to 1st screen. Enter name and email address. Press continue. The screen spins and does not stop. Not after 10 minutes. I had tried earlier and got did get to the config screen. But was having problems. Cleared cache in Firefox, and then could not get past the 1st screen. Also, screenshots show how to add account shows three fields - name email, password. But I never saw that screen. That was a more old school style screen. he current screen I see has dark blue background, more modern style. See image attached. I had previously gotten past this screen, now I can't. Please help! Thank you

Trying to set up a new email account in Thunderbird I go to the Account Hub, enter the name and then the email address of the new account and select <Continue>. There then appears a greyed-out box showing "looking up configuration" with the usual turning circle indicating waiting for a response. After three hours still greyed-out with the turning circle and no response. I have tried several times. Please advise a solution

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

Been using Thunderbird for years with these accounts. Just today outlook accounts failing to login. Accounts do not receive email. Can not send email. Checked server settings, which were unchanged and obviously worked previously. Tried deleting passwords in password manager and re-entry. Failed. What's up with the outlook connnection?

Seid einer Woche habe ich keinen Zugang mehr zu meinen E-Mails. Es sagt mir jedes mal "Anmeldung auf dem Server imap.gmx.net mit Benutzernamen "thias.weber@gmx.de" fehlgeschlagen" Ich hatte zuvor nichts verändert und alle eingegebenen Daten sind korrekt. Auch eine Anmeldung auf einem anderen Gerät oder bei einem Freund (bei dem alles Funktioniert) führte zu keinem Ergebnis. Neuinstallation auch nicht!

For a week, I haven't been able to access my emails. It tells me every time "Login to the server imap.gmx.net with username 'thias.weber@gmx.de' failed" I hadn't changed anything beforehand and all the entered data is correct. Even logging in on another device or at a friend's place (where everything works) did not lead to any result. Reinstallation doesn't help either!

pleace help!
