Thunderbird Community Forum

For a week, I have not been able to send any emails through Thunderbird.

This is the only day that I have been able to delve further into the problem.

If I send an email, this is the response that I get after sending. Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) smtp.gmail.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again.

I have contacted my main provider and they have been useless. I contacted my secondary provider and they sent me what the settings should be. I checked their info against mine and everything is correct.

I prefer Mozilla products over all others and I wish to get this corrected sooner later, I have two assignments to send over the weekend.

I would rather being doing something else that trying to figure out this problem.

I should be celebrating or mourning the passing of my wife 3 years ago, than trying to figure out what is wrong.

One thing I did do was to go to the Mozilla website and download Thunderbird again in case there was a conflict somewhere in the system.

Thanking you in advance. K

Nov 2024 - How Do I disable Threads in the Email folders?

My Inbox I think I somehow disabled, but my SENT folder....still has them. Please help. I HATE this as a default setting that can not be turned off...Universally..(in all folders)

Thanks

Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.gmail.com timed out. Try again. Claude Hamel landbaron52@gmail.com

Unable to send emails from my Laptop. Drop down box says "Outgoing server (SMTP) failed. I have compared settings on PC and are the same as the laptop. Have contacted my server provider and that is all ok. Can send emails from Optus webmail, but not from Thunderbird. Can send emails from the PC and that has Thunderbird also.

Threads are a pain. It seems that Thunderbird decides when to create a thread and then emails no not appear in date order on the inbox list. Clicking on "ignore threads" seems to lose them completely rather than ingnoring just the thread. Any future emails on the old thread can only be found by searching for the sender! Please, Thunderbird, allow me to chose if I need a thread. Also, how do I disable threads completely so that incoming emails appear in date order in my inbox?

I tried to Send an email, but the Send option at the top left of the email has changed to Send Later and the email does not send.

How do I change that option back to Send?

I need to change my password however I am not succeeding.

I am trying to change it from the following path : Settings - Saved Passwords.

Once in the above path, I type in my new password and press close.

I then close thunderbird and when re-opened a pop up window appears to type in the password. When typing in the new password, the following error comes up:

Login to server secure.emailsrvr.com with username ------------- failed.

For thunderbird to continue working, I need to enter my current 'old' password. Somehow it is not recognising the new password.

Can someone please help ?

I recently changed onto the new release channel by installing version 136. I now find that this new release channel appears to have installed version 138, but it is reported as a beta version. I do not want to use beta versions, as I am having a lot of problems with it, so how can I return to a stable release?

All my emails in the inbox are not showing except for today's emails. At the top of the thunderbird email program is a search box. I searched for a couple emails I remembered the names of and showed me a few from last year. I am hoping they are all still on the server. How do I recover them and return them all back to the inbox?

Can't this problem be solved, the other clients are doing well :man-shrugging:

I wanted to say thank you, but the post is in the archive. https://support.mozilla.org/en-US/questions/1197767

Thank you very much!

The year is 2025, version TB 128.6.0esr (64-bit), and your solution is working!!! This is a real problem, IMHO! I looked at the TB at lunch, there was no letter, I look at the letter in the evening and he writes to me that it arrived at lunch. It looks like I’m blind :(

My email messaging seems to be set at a defined format with double spacing. I prefer to use single spacing but in order to do this I have to type all the way to the end of the page and then it will automatically go to the next paragraph and will then use single spacing. I would really like to be able to format my emails with single spacing and different margins other than what I have to use now (i.e.using the entire width of the message). I cannot find any way to change this automatic double spacing and change the width of the paragraph at the same time. From the drop down list directly above the body of the message, I have tried changing from Body Text to Paragraph and back again, but nothing works. Thanks very much for your help.

P. S. I am using Windows 10 with Thunderbird version 128.4.2 esr. I had the same problem in more recent versions but not in older versions.

Email errors started occurring on or about November 25, 2024. Multiple calls and tech support with Spectrum techs and hours of troubleshooting brought about O results. I obtained all necessary protocols for configuring email to Spectrum requirements and for sending and receiving, but I still get outgoing errors. I have been using Thunderbird for 5 years or more now and never had any issues until now. Upon inspection through Thunderbird tools/setting/ looking at "SAVED" passwords, I no longer see "IMAP" or "MAIL" access protocols. It was there previously. I also disabled all my firewall and vpn settings and still cannot send out any emails. I have thoroughly checked out both my personal email setting and my small business email settings and everything as it relates to Spectrum is correct. Spectrum said one thing they found was that the email settings (specifically, would not resolve with the server because of a syncing problem). Spectrum did all they could to resolve on their end, but the issues, as they see it now resides on the Thunderbird side. In an effort to resolve the issues, the Spectrum tech looked and looked for a phone number for Thunderbird and said this is the first time he has never found a number that one can call for some sort of assistance. Emails directly to Thunderbird are very, very slow. And to compound the issue, there are no lists I could find is a repository for error codes and no valuable tech support or specifications could be found that provides any real help for resolution. So now I am making a last ditch effort to contact Thunderbird for a one on one phone conversation that will resolve all the issues I have encountered. Hopefully with your immediate reply, we can resolve these issues and I will be able to help others resolve these same issues. These issues are not just isolated to me. There are literally hundreds maybe even thousands of people out there with the same issues. PLEASE contact me asap. Thank you for your time. (PS. I do receive some messages via email, but sending out is the issue)

I have to change my email accounts by the end of the year. I've been manually moving folders and emails from old account to the new. Then I would like to copy 'Message Filter' from the first account to the next.

Is there a guide or an app to do this? The Message Filter is probably the most important thing I need to do.
