Thunderbird-Hilfeforum

Greetings: Here is an error message that is now so common that I can no longer send email to any account. Also, I have not been able to send email to any gmail account for last year or two. Please help. Error Message:

"Sending of the message failed. An error occurred while sending mail. The mail server responded: <MattMcKeegan_PLS@proton.me>... Relaying denied: You must check for new mail before sending mail.. Please check the message recipient "MattMcKeegan_PLS@proton.me" and try again."

Thanks. Matt.

I am using Thunderbird v 115.5.1 on a Windows 10 system. I am using an "@hotmail.com" email address. I seem to be able to receive emails just fine, but face an issue sending out emails. When I press "send", it gets stuck on "sending message" for quite a while, then I see the error message:

=

Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.office365.com timed out. Try again.

=

My SMTP settings: Server Name: smtp.office365.com Port: 587 Connection Security: STARTTLS Authentication Method: OAuth2

Appreciate any help! :)

On Nov28 changed to Rel 115.5.1, my thunderbird can receive messages but can not send. I am getting an error message saying that my password is in error. However when i go to Mail.aol,com my password works fine. again this just started on the 28th.

I recently (on the 28th Nov '23) updated TB to the latest version. It was so awful though that I uninstalled it and reinstalled version 60.9.1. However, now my address book is empty. I did have an old csv file which I was able to import, but it's quite old and missing a lot of addresses added more recently. Where did the saved email addresses go? Are they likely to still be out there somewhere? Thanks, Ian

I have 2 email addresses with Comcast linked to the same account. I was always able to send an email from either address using Thunderbird and the dropdown in the "From" box. I now receive an error "Sending of the message failed when using the alternate email address. An error occurred while sending mail. Thunderbird responded: "Sending of the message failed. An error occurred while sending mail. The mail server responded: Please ensure your email address and authenticating user match when sending messages. Please verify that your email address is correct in your account settings and try again." I do not know when this started. It had always worked (YEARS). It works on my iPhone mail - it's just Thunderbird. Any suggestions would help....Thanks

'i am now using thunderbird to get my emails. i have two accounts- aol and gmail. when i open the thunderbird app, the emails are not joined, they are separated and i have to scroll to each account to review my emails, is there a way to join both accounts and review both aol and gmail emails at one time? thanks

Hi folks, I am wondering if there is some way to change the Thunderbird icon showed on Win10 Taskbar, when TB is opened. After change to TB115, I find the default icon very inconvenient, as it looks very similar than other icons of other software I am using (e.g. Signal app) and it is difficult to locate TB on the taskbar, if many windows are opened. I found a way to change the Icon of TB showed on taskbar (pinned icon), if TB is closed. I use the one of defaults with the small red dot. But every time I open TB, the icon change back to the default blue with white middle and WITHOUT the red dot. Any help is appreciated.

I have been unable to get Thunderbird Version 115.5.1 to return any text search results. I use the Cmd-K global search bar. No matter what search term I enter, the search results tab remains completely blank. So I cannot perform text searches across folders.

I could always do this in previous versions of Thunderbird.

I have run in troubleshooting mode, dumped a lot of excess email, and re-indexed.

What am I missing? Thanks in advance.

Running Tbird on a Mac Mini OS 13.5.1

When I try to set up Thunderbird on a new computer, it won't connect. And Thunderbird changes the port settings that the provider uses to something else. So I can't use thunderbird with my email address: sheilah@got.net

For some reason particular emails i receive from known senders who's addresses are in my address book end up in the "Spam" folder. These are usually replies to emails i have sent. If i forward them back to my inbox, they eventually end up back in the spam folder. The alarming part is that the list of addresses going to spam is growing.

I have several email addresses on Thunderbird, but only my gmail is affected.

Any ideas how to fix this B

Dear Support Team,

I am facing an issue. Whenever I double-click an email from my inbox, it opens as a draft email.

I tried a couple of things by searching on Google but couldn't find the solution.

Please help me.

Email that I am sending from Thunderbird is being rejected for no apparent reason by the recipient server. This is not due to an ISP or sending server security issue since, when I send exactly the same email from my ISP email web page (not Thunderbird) the email is received properly and accepted without error. So, the problem is most definitely with Thunderbird. The following is the header text from one of the rejection replies.

Do not reply that his is an issue with my ISP. It is not. It is purely a Thunderbird issue. Thanks for your time.

Hi everyone! Apologies upfront in case this question has already been asked, but I'm struggling to see if something similar was already posted... In a nutshell: I delete messages in my inbox (or any other folder) in Thunderbird, but when I login to the website of my mail provider (gmx.net) or check the app on my phone, I still see these mails on the imap server. Is this a known issue? What could be the reason?

How can I prevent thunderbird 115.5.1 from expanding my zip attachments prior to mailing? Even though the zipped file is below the 5 meg maximum, Thunderbird unzips the file as soon as it is entered as an attachment thus making it above the 5 meg maximum.

Hi, I did put a sender of a daily newsletter in the address book. I did use "Mark as Not Junk" with every newsletter of that sender in the last couple of months. . But Thunderbird always and every day lists the newsletter as Junk. (the sender is Smithsonian Magazine) So training the Junk filter does not work. How to change this failure of Thunderbird? Thanks for your attention and answer.

I'm trying to migrate old messages (stored under pop) in an outlook .pst.

choosing Tools, Import, then selecting Import from Outlook, immediately gives a "No Profile Found" above the import tool.

I'm not even clear if this is referring to a Thunderbird profile, an outlook profile, or possibly a file in an import directly somewhere?

anyone have suggestions?
