'Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) mail.btinternet.com. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'.

Hello

I have been using Thunderbird as my email service and not had this before. Yesterday, I had to change my password for emails with BT. I changed it on Thunderbird too but now I am receiving emails OK on Thunderbird it is refusing to send any for me and shows the above message. I can send OK from my web based BT email but prefer Thunderbird.

I haven't a clue what I need to do to solve this.

Can you please help? Please tell me is very simple steps I'm not very computer savvy.

Thank you

The height of the viewing panel for emails is far too small. I can only see a couple of lines of text at the most and am unable to reduce the height of the incoming list of emails as previously in order to increase the height of the viewing panel. I have been helped to increase the font size of the overall layout so that I can now read it better but the green button to declare that my problem has been solved tells me that the page isn't working!

Urgent Help Please as lost ALL EMAILS - I cannot get to post in Thunderbird: 1) I've now spent 4 hours, (from what was trying to sort a 'simple' problem on the server), as I couldn't send or receive any emails, as they think I've 6.5Gb of data on it, in spite of my deleting all my emails off it. So they allowed some extra space to temp sort it again. It's been an issue for about 3mths now. But I deleted everything just the other day having confirmed that was not deleting them off my laptop and that the previously lost emails 2 yrs ago weren't still on their server.

But now checked back on my email client Thunderbird, and I've no emails. They're all GONE bar the odd few I've put into folders (I stopped using folders years back as that lost all my emails way back then!), so I'd been keeping them all in the Inbox. Although I've a few old Inbox files with previous old old emails in so I can access them if I need to. But at least their there! But now again I've just lost everything. This is such a disaster.

Over the last 2yrs it's been going OK until today. Now it's LOST ALL MY EMAILS. I'm as per usual up to my eyes and have to travel this friday for meetings next week. The last thing I needed today was this. I've lost so much data and info in those emails it's doesn't bare thinking about. From show tickets that I need, medical info and data, to flight details to all sorts of crucial data. My ONLY saving grace is that anything I've replied to, I have a copy in the sent folder.

So Please Forgive this being in Firefox, as I can't even add it to Thunderbird help area!! I've had to reset my pw too just to sign in. Sadly right now it all feels so very upsetting I'm thinking I'll have to just have to start using another email client! If every 2 yrs I lose all my emails then this is just not acceptable. I hope you can move this to the Thunderbird threads. If you do please send me a link to it so I can try and find it.

What's so upsetting is had I saved the Inbox file when I saw the 13Gb file size, a bit eariler then, I think I could have saved them. I fear though that the remote server people deleted something, that was somehow still linked to my system and that's meant they've deleted my emails off my laptop too! Terrifying! (Perhaps that is what happened before back in '22. ???) I did look at a 'Sync' settings but not sure what they did so cancelled back out of them.

Running on Win 10 Pro 64Bit i7core 8Gb Ram Thunderbird 115.10.1 (64-bit)

Any and all help will be most gratefully received.

Sub issue to get help : 2) Error to Sumbit to Thunderbird: Sadly I've gone around and around your system saying Ask Question when nothing answers my query on the Thunderbird email questions. But when you click on Ask Question it just takes you back around the system again / Browse all Programs / re click on thunderbird/ reclick on Emails and back to list of FAQ's but nothing helps so click on Get Help and back around you go in a deja vu system.

I used to be able to select a range of e mails using the cursor to select the first e mail and then press shift key and the last email with the cursor to select the range of e mailsin my inbox to delete them. I could use the delete key, the button in Thunderbird or right click to bring up some functiosn such as delete selected messages. When I do this now the messages, which are normally unread, show as read but have not been deleted. I try again with the now read messages but they still will not delete. Its fustrating

""Description: COX Server Name: smtp.mail.yahoo.com Port: 465 Connection Security: SSL/TLS Authentication method: OAuth2 User Name: your user name, duh - Mine keeps changing the user name to the last name I put into any of my 6 accounts. The only way it will send mail is if the correct user name is in the correct account (obviously). Why is it changing constantly? click OK""

I've read the "fixes" from 2023 and they do not work for me. I tried changing the DESCRIPTION to blank, didn't work. Changed them to the corresponding e-mail for the account. Didn't work. Changed it to "SMTP" with the corresponding e-mail. Didn't work.

It keeps changing the last one I edit to the one I edited before it. It's driving me crazy. Won't send mail unless the User Name is correct (obv.)

Whole mess started when forced to switch from Cox to Yahoo recently. Seems to be working other than TB changing the name as soon as I type in the next one in the next email address and then it not working until I change the User Name back to the proper e-mail address of the 6 accounts.

I drag-n-dropped an account (POP3) folder "inbox" to the "Local Folders". How can I return the "inbox" folder back to my account folder ? Drag-n-droping back does not work.

I have three different computers that I can use Thunderbird to access my hotmail account. All three computers can have the exact same server settings. One computer refuses to send emails unless I cancel the send and immediately resend.. Thunderbird ver 115.10.1 (64-bit) Windows 10 Home Ver 22H2 IMAP Mail Server outlook.office365.com Port 993 Connection Security SSL/TLS Authentication 0Auth2 Outgoing SMTP Server smtp.office365.com Port 587 Connection Security STARTTLS 0Auth2 Take Note All three machines can have identical settings listed above or various changes like Normal Password instead of 0Auth2 and/or an Outgoing server can be smtp-mail.outlook.com with normal password or 0Auth2... One computer must be cancelled will sending and when resent, it goes... no problem...immediately. If I don't cancel and wait, for it to send on the 1st attempt, it will eventually timeout on the outgoing server. Then I might have to reenter a password. Very annoying. I have been doing this for years. It is my workaround....

I deleted Thunderbird, than Installed latest version. Now in Thunderbird "Use Primary Password" is clicked so I can't reset primary P/W. Previous P/W doesn't work because there is no P/W there as far as I can see. Instructions I found: "Tools> Developer Tools> Error> etc. There is no "Error" button. Instead I get Incoming Connection (attachment) and an other screen that I don't understand. Can you help please? Thank you Ilio Pieroni

I have had Thunderbird email account for years and now I have problems getting my emails to come through on a regular basis. I have to shut down my PC and then restart to get emails to come through. What is the problem. Thanks, James Craig Herring

I sent an email with multiple BCCs and no CCs or TOs, I put myself as one of the BCCs.

I did not receive it and I do not think anybody else did as well since I asked a few people.

The email is in the sent folder. I tried forwarding the email from my sent folder to myself as CC, and that worked. I also tried fowarding as BCC, and that worked.

So what is going on? Is BCC working? How can I know for certain? Do I need to foward the email as BCCs to all my BCCs to get this to work?

Thanks for your help.

Hi.,

 Cox cable just discontinued their email server and moved all it's email accounts to Yahoo.

I had been using Thunderbird successfully with Cox for several months before this happened.

 I am able to send and receive emails now via my new online Yahoo server;  however I have not

been able to connect / use Thunderbird to send and receive emails since the Yahoo changeover. I have tried many things, but I either get a "failed" error message or a "timed out" error message. Yahoo support has not been able to figure this one out. They are hard to get a hold of and hard to understand (communicate with). They are overseas from the US.

 I appreciate any help you can offer.

Kind regards, Ken

I was subscribed to a large distribution list, but then unsubscribed. But I didn't unsubscribe. So I subscribed again, but was soon unsubscribed again! My email address and password may have been hacked. So I logged into my Comcast ISP and changed my email password. Then I started Thunderbird, and as expected, it asked for my password, and I gave it. My email came up. I tried sending an email and it asked for a sending password. I ignored it, but after a long delay, it refused to send the message. So I tried again, this time giving it my new email password. The sending then worked. I assumed all was now OK.

But, as a final test, I exited Thunderbird, and then restarted. It again came up OK with my emails shown. Then I again tried sending a test message to myself. But it again asked for my sending password! Thinking this might be a scam, I put in a password of "bullshit". Then I received the following popup message:

Sending of the message failed. An error occurred while sending mail. The mail server responded: Polite people say HELO first. Please verify that your email address is correct in your account settings and try again.

What!!! It sure seems like someone (at Thunderbird?) is in the loop grabbing my password before encoding it for storage. A similar thing happened in the past, where I think my account was hacked. So, was this a hacking attempt, and if so, was it from Thunderbird software or my Comcast ISP?

Windows 10 Pro Desktop PC I am using Tunderbird for my gmail account. Version 115.10.1 (32 bit) Ever since there was a update (upgrade?) to gmail I can no longer use Thunderbird for my gmail. I don't know if it's at the Thunderbird end or the gmail end.

Here are the messages I recieve: First is on the actual email message and the second is a "pop-up" msg in the lower right of my screen.

Error on the composed message: "Your message was sent but a copy was not placed in your sent folder (Sent Mail) due to network or file access error. You can retry or save the message locally to Local Folders/Sent Mail-Rick.Reckage@gmail.com"

Error message at bottom right of Thunderbird: "Connection to server.imap.gmail.com timed out"

Thank you for any help to fix this. I like Thunderird so I contribute. I want to be abble to continue using it for gmail ifmpossible.

Now i do not want recreate a new profile and lose all my contacts book marks add on etc. how do i remove that yellow bar in Thunderbird mail

Computer crashed. After restoring, Google calendar is not syncing. No error message that I can see. I unsubscribed and resubscribed to no avail. I have no clue what to look for and searching here is not helping as all the references to this are years old. Can someone help me figure out why this is happening?

In a recent email Thunderbird sees an HTML message as plain text, and does not decode it. The message is decoded by my phone using "Email - Fast & Secure Mail by Edison Software". See attached screenshot. Normally Thunderbird suceeds where phone apps fail.

All other HTML messages seem OK

Several days ago, my comcast email said it couldn't connect, and after trying a couple other things, I removed the account and tried to add it back on. When I try to add it as an IMAP account, it pulls up a window that loads for a minute then says "Unable to connect. An error occurred during a connection to localhost." On the thunderbird window where I entered my password, it says "Unable to log in at server. Probably wrong configuration, username, or password." I logged in on a browser, so I know the username and password are correct. I tried adding it as a POP account, and that worked fine, but I need it as IMAP.

So running thunderbird 115.10.1 (64-bit) and more and more issues:

• the app keeps getting non-responsive for long period of time, to fix this I have to force quit the app.
• at times when composing an email the app freezes where no typing occurs for seconds or typing is very slow or after typing awhile the text suddenly appears.

Seems to be happening more and more trying to figure out how it can return back to it's rockstar state when it was <99 version.

any help would be appreciated.

from today I cannot download my gmail to Thunderbird, I'm getting always here below error code:

“400 invalid_request” or “Access blocked: App sent an invalid request,” it means the app uses an authorization method that Google doesn't allow. Google has safe ways for you to sign in and share your Google Account data with third-party apps and sites.

Please let me know how to proceed.

Thank you
