Thunderbird Community Forum

Hello! All the messages in the sent folder have been lost. When I use webmail, all the messages appear normally. I sent a test message from Thunderbird 151.0 (64-bit) / Windows 10 (64-bit) and the message does not appear anywhere in Thunderbird, but I can see it in "webmail". I added the same email account to TB on another PC and I have the same problem. I have deleted this specific email account from TB and reinstalled it, but the problem persists. In Outlook (iPad and PC) it works normally. Other email addresses of the same domain work normally everywhere. The email server provider cannot help me and claims that there is a technical problem on my side. Is there anyone who has any idea on how to solve this particular problem? Thank you.

Gidday I have been using Thunderbird for sometime and recently had to re-install the program so now I have the latest version of it installed but the program isn't removing the emails from the server. I can't locate the "delete from server" setting anywhere in the options. I have searched everywhere for an answer here and on the iterweb so would appreciate if someone could provide help please. cheers col

I regularly get the following message when attempting to send an email :- "Sending of the message failed. The message was not sent due to exceeding the allowed number of recipients. The server responded: Policy-SC01 You’ve reached your sending limit. Don’t worry, you can send again soon.." This message implies that I am attempting to send a message with multiple recipients, BUT it only happens when I am sending to only ONE recipient. Why is this, and how do I eliminate this very annoying restriction. I currently cannot send an email because this problem is preventing me from doing so. Thunderbird has been a useful email client for many years, but these frustrations are not helping me to remain with Firebird. Regards, PD

On my home computer, all my sent emails go automatically to the Inbox, not into the Sent folder. Now using Thunderbird on a laptop and I can't remember how I set that up. Grateful for help.

I have successfully set up 3 email accounts using my default domain. When I try to use an email account that uses a second domain I can't send or receive emails. This account required manual setup which I did but it does not work. My web hosting is with Namecheap and I do believe settings at that end are correct. Any help would be appreciated.

I use Thunderbird (102.15.1) at home for emails on my Gmail account, and I have a lot of local folders for filing of emails. I also have Tbird (115.10.1) on a laptop for travelling, but without all the local folders. When I opened up Tbird on the laptop, it downloaded 2 years emails (!!) -- they are all, of course, already on my home computer. If, for example, I delete most of them on the laptop, can I be sure that will not affect what is on my home computer?

I know I need to upgrade to Tbird (it will be v. 128) on both computers.

Are there any guides or instructions on the interaction of Gmail and Tbird on 2 computers?

All help/advice will be appreciated.

Wise, a currency transfer business, claim to have sent me several emails as part of a two stage verification process. But they never arrive! They will not accept that the problem is at their end, they say it must be my email programme which is Thunderbird. I have searched everywhere but they aren't to be seen. They say to look in my spam folder but Thunderbird doesn't have one - Thunderbird flags up what it thinks is spam, (usually correctly), but still deliver to my Inbox. Has anybody any suggestions as to what I should do? Until I login, I cannot use my account.

It's been almost a week now, and my 2 Microsoft email accounts will not connect to Thunderbird anymore. All was fine for years, but something changed that I can't figure out!?! I have gone to my Microsoft email server and checked that my passwords still work. I even updated one and it works on Microsoft server but not Thunderbird's!?!? I even deleted one email account from Thunder bird to re-install it, but when I tried a fresh re-install Thunderbird still won't connect to Microsoft server??? I'm at my wits end, and may abandon Thunderbird completely if someone there doesn't help me connect!!!

Attempting to install Thunderbird on an additional desktop using same address as my original computer has. That was my question:

Lin answered: Please quote any and all error messages you see, in full, verbatim. Screen shots would be OK.

Who is your email provider?

Have you compared all account settings, not just the email and password?

Here's my answer to those questions: "Authentication error" "probably wrong configuration, username or password."

My email provider is MTA (Matanuska Telephone Association) Yes, I currently use Thunderbird in my other desk top and it works fine.

Hi Below is the message I get when I try to send an email from my new computer

Sending of the message failed. An error occurred while sending mail. The mail server responded: <mary@maryodonnellaccounts.ie>: Sender address rejected: not logged in. Please verify that your email address is correct in your account settings and try

Thank you Mary

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 want to use thunderbird on a Windows 11 laptop. Tell me how to connect Thunderbird to send and receive emails from email account, jds@sefcik.net, hosted at smartmail.buz.net.

I have seen this problem with roadrunner listed in the forum but my situation is a bit different. Neither my wife or I can send or receive roadrunner emails with different machines. She uses a Mac (sonoma 14.8.7), up to date, I use Linux Mint ver 22. We also have iPhones and iPads. none of these units send or receive emails for the last 24 hrs but all worked just fine before. Spectrum says it our problem not theirs. The tech person at Spectrum said they partner with Thunderbird but they did not know of any changes made.

I have changed passwords used different routers and anything I can think of to connect but the devices now all time out when trying to connect.
