Thunderbird-Hilfeforum

I've provided all of the other data, no problem. But the <Your login> field has only "YOURDOMAIN\yourusername" in it as a format hint. The field carries an Info symbol, but it's greyed out.

There are many possible domains, e.g. microsoft.com, office365.com, outlook.com, each with possible 3LDs, and the domain-name of the organisation that provides my account.

The most obvious (MYORGDOMAIN\Roger.Clarke) gets the error-message: > Authentication failed. Please check the username and password. (I checked, and they're the same as I use for a webmail login there).

Leaving it empty gets this error-message: > Unable to log in at server. Probably wrong configuration, username or password. (That about covers the possibilities then ...).

I am unable to send emails. I am asked to enter my password and have tried many times. The instructions to enter my password just keeps repeating over and over. I am at a loss as to what to do. Any suggestions?

Cox.net is transitioning from in-house e-mail to e-mail handled by Yahoo.com. Our cox.net addresses are supposed to (and apparently have) transitioned so that they still work, but are processed through pop.mail.yahoo.com.

It is my turn to be transitioned and I have been successful in doing so to the extent that I can send and receive using my address(es) ...@cox.net through Yahoo web mail and on my Samsung phone. I have not, however, been successful in either sending or receiving mail using Thunderbird on my desktop.

I have been successfully using Thunderbird with POP settings for years with four different cox.net addresses. [I'm currently just trying to get two of them working -- unsuccessfully.]

I am using Windows 10 on a Dell desktop. I am using Thunderbird 115.9.0 (32 bit). I have reset the POP and SMTP settings as directed by Yahoo. One of the errors I receive is: "Error with Account .... Sending of password for ...@cox.net did not succeed. Mail server pop.mail.yahoo.com responded (SYS/TEMP) Server Error - Please try again later." It then asks me to retry or enter a new password. I have checked the passwords saved by Thunderbird and they are correct.

I suspect, that with all the Cox accounts being newly routed through Yahoo servers that I am not the only Thunderbird user experiencing this problem. Does anyone have any suggestions? Is it likely to help if I uninstall and reinstall Thunderbird? Would I loose all my mail, etc. if I did that? [I did the delete and add account in my phone and that was successful, but I wasn't concerned about losing mail there as it is all on my desktop.]

Thanks in advance. billb1111

TB no longer will start. It just hangs and when I go to it on my Mac I see a spinning disk. That never changes and eventually, after hours, I must force quit and report it to Apple. I receive no messages or error codes.

Suddenly unable to send any emails. Able to receive / read. In Charter / Spectrum able to send. Port numbers are correct (143) for Incoming & (25) for Outgoing SMTP. Did try to change Outgoing Port to 587 per one of your posts. Didn't work. This is error message I get.

I'm using the latest version of THUNDERBIRD for WINDOWS (now 10 HOME), but this problem has existed for years with previous versions of THUNDERBIRD and former releases of WINDOWS, both HOME & PRO releases. And, it seems to be very specific. When i receive e-mails from (especially) 2 friends who both use AOL as their e-mail client, when I receive them, the imaged files (or memes) are always 'converted into attachments, and what shows in the Body Text of the e-mails is empty boxes. Yet, when I get e-mails from others, including from commercial sources, if there are images within the Body Text, they are present there. This IS very annoying because many times the e-mails I get from these two friends are technical e-mails, with clarifying images as part of the Body Text. When I have mentioned this to them, their responses are that n one else complains, only me, and so the problem MUST BE at my end, but that doesn't make sense, since when I receive e-mails from others (Gmail, etal.) any included images are fully where they belong. ++++++++++++++++++++ Secondly, WHY is it that when there are threaded e-mails in the Sent folder, the ARROW to expand the thread appears at the left side, but in the Delete folder the ARROW appears between the title of the e-mail & the next column? This IS very annoying!!!! Also, when I'm in the DELETE folder, sometimes only two options appear at the right side: Archive Delete, BUT in other incidences, there's a plethora of alternative options, and the Delete option is positioned in a different place. More often than not, I click on the option to send it e-mail to the Archive folder, when I really wanted to Delete it permanently. Another major annoyance!!!! Thank you robert herold

I have 4 e-mail addresses and corresponding inboxes. One is my personal addy that I use for most legitimate business. The other 3 are leftovers from former businesses and a spam addy. I use those other 3 addys sparingly, but only for sites I want to maintain distance from, and any I suspect might be spammers.

Thunderbird has worked wonderfully for me for some years, but recently, I have been getting duplicate messages in 2 of my 3 dummy accounts for every one that is legitimately sent to my main account. None ever show up in that 4th account, but I did just receive an e-mail that was intended for that 4th account, and the inbox acted as it should (no duplicates anywhere).

I have spent a couple of hours with a very dedicated service rep from my ISP, and she was unable to find any solution. She suggests that reaching out to Firefox is the next logical step.

Hello from one of my mails I can`t see the external issues. I gave permission to show all content in the mail, and that was stored in the list permission to show all external content, but still the content is not shown. Can you please help me, and tell me what I can do so I can see all the external issues in the mail.

Thanks and with regards, Henny Noorman

Shortly after the 115.10.1 update, I've noticed that emails are downloading, but either only a few show in the Inbox or none at all. I've never had this problem with Thunderbird before. Is there some invisible spam/junk folder that I'm unaware of?

I'm using POP with Dreamhost. Is anyone experiencing these disappearing emails?

Hello My Thunderbird failed pop access to my Gmail account, at beginning of month. Any try to fix, and even change from pop to imap don't work. I get the windows as shown i images as result.

Any hint on forwarding step? Thanks Lars Granath

Thunderbird runs slow...ie when I type an email I can easily type faster than thunderbird will accept characters....(this does not happen in other applications)...this happened about a month ago, and then stopped ( I have no idea why)...but the problem is back. I am running Ver 115.10.0 build 2024012173147. Rebooting windows 11 makes no difference.... I just tried to enter Troubleshoot mode and thunderbird stopped responding....Top line says Mozilla Thunderbird (Not Responding). Thunderbird is connected to my gmail account. ...and I run IMAP....with 'store all messages on the computer', but thunderbird wants to load every email from the server'

Any advice would be appreciated Rick

Without having done any active change: For some time TB seems to not have passed on mails from my alternative mail account. I cannot seem to find the previously functioning gmx account in my settings.

For two days now I do not receive any mails at all. Apparently I can send them, though.

I restarted the programme and tried in safe mode, to no avail.

I am a simple creature, please advise or enquire in a manner an exhausted non-tech person may be able to follow.

An IMAP mail system is configured on a server running Debian 12. While there are never any problems via webmail, reception and sending work occasionally via Thunderbird 115.9. Even in "Troubleshooting Mode" it doesn't work. The server has good hardware characteristics and there are no applications that can slow it down, nor do I think it is a firewall problem or incorrect parameters otherwise it would never work. The error is related to timeout reaching the server. What can I check to find out where the problem is?

Junk, Bin, Deleted confusion in email account There is confusion in Settings regarding Junk,Spam, Bin,or Deleted. When setting up Spam checks it refers to Junk folder where I have customarily used Spam folder and or Deleted/ Bin folder options which am now not able to set in the options available. Is there any way around this. I use' Ubuntu Linux' and 'Android (Gmail')? Thankyou Walter Reed t.walterreed@gmail.com mail@walter.plus.com

MacOS Sonoma 14.4 seems to have broken a number of apps. AFter updating to Sonoma 14.4 I experienced a great number of crashes with Thunderbird, so I completely uninstalled Thunderbird and removed all traces of plists, Application preferences, everything, reinstalled Thunderbird, and added back the two email accounts I use with it. It now takes up to 30 seconds to start up Thunderbird, after which it happily no longer crashes, but obviously the startup time is unacceptable. I experience the same problem with Typora, and the developers there informed me that they believe the problem is with a Sonoma change that broke WebKit. I don't know if Thunderbird still uses Gecko or if the new version is WebKit. Please let me know if other Sonoma users have reported this problem or if it's just my system.

'just added 2nd gmail address to Thunderbird. Suddenly getting verification requests. I go through that process then asked for phone # for verification code only to be told the number already used too many times . Now what?

Already invested time creating some html code for email signature on thunderbird. Wanted to create something prepared for dark modes on IOS. Everything was fine until I detected on IOS (dark mode)some white rectangles outside my email signature code. It´s a problem that I cannot solve because it´s outside my code, and I´m wondering if you are already aware of this issue.

In case you want to test my code on a Thunderbird HTML email signature and see the result on an iPhone (dar mode), you can get it here: https://codeshare.io/dekBnR
