Forum zhromadźenstwa Thunderbird

Hello, I have problems to use Thunderbird client in my Win11 laptop. In late 2023 windows introduced modern authentication and after that I have big problems to have just any mail client to work. I used to use Outlook classic but that one failed I stared to test different clients e.g. Thunderbird, Mailbird, emclient but with no luck! My feeling is that it has to do with my Windows 11 installation. The process always fails when trying to log in to the IMAP server. When googeling around my impression is the Thunderbird should do it - but sadly not in my laptop.

I decided to dive into the details and try to find why it fails, so please see below analyse.

Regards Stefan

Problem description: Thunderbird 128.6.0esr(64-bitar) works in Windows 10 environment but same thunderbird version fails to log in to IMAP-server in windows 11.

Analyze logging created using .bat file with: set MOZ_LOG=IMAP:5,timestamp

       set MOZ_LOG_FILE=%USERPROFILE%\Desktop\imaplog
      "%ProgramFiles%\Mozilla Thunderbird\thunderbird.exe"

Observation: Windows 10 where login works: 2108499af00:imap.privat.bahnhof.se:NA:ProcessCurrentURL:imap://mb111111@imap.privat.bahnhof.se:993/select%3E.INBOX: = currentUrl

Windows 11 where login fails: 243f98e5900:imap.privat.bahnhof.se:NA:ProcessCurrentURL:imap://mb111111@imap.privat.bahnhof.se:993/select%3E%5EINBOX: = currentUrl %3E = ”>” %5E = ”^”

It looks like the dot (.) has been incorrectly coded. Is this difference the problem and is it connected to windows 11 or?

Details from logging:

Since January 13, 2025 Thunderbird has not downloaded any emails.

I set the TLS setting from 3 to 1 and closed and re-opened Thunderbird, but still no downloads. I am able to send messages. I have turned off anti-virus programs, but still no downloads.

When I click on the download button or select the File option to download messages, no information is displayed, and nothing happens.

I have check if there are new messages to download from Optus by logging in to Webmail. I have successfully emailed a message from Thunderbird.

I have contributed to Thunderbird development because it is the best, and I have used it since its first availability. Now I am without it.

Please inform me of how to fix the problem.

In transferring my profile from PC to laptop, something went wrong and I lost all of my local folders, with years of emails in them. I have searched all parts of the Thunderbird folder under Roaming, and have been unable to find the folders.

The weird thing is that when I do a search for a particular subject or email that I know was in one of the local folders, the search still gives results showing the email headings. It will, however, not display the results as a list or open any of the emails.

The fact that the folders and emails appear in the search leads me to believe that they are still somewhere on my PC.

Does anyone have any advice on where they might be or how to find them?

I'm using Version 128.6.0esr in Windows, but can't do drag and drop file for attachment at all. Previously it still can use this feature but suddenly it came to a stop.

The icon Ø will appear when we are trying to drag and drop a file to the create message window.

We already have tried the troubleshoot with no result.

Any advice on how to repair this?

Thanks

Hi,

My trash refuses to stay deleted. I delete it and close Thunderbird. The next time I log in, it's back in the Trash folder. This has been going on for over a week.

I have had Thunderbird for years so I know that it isn't in my settings. What is going on?

Since January 8th, 2025 I have not been able to send or receive mail on a regular basis out of Thunderbird. the strange thing is sometimes I can start Thunderbird and it will maybe download current messages, but won't work the rest of the day. Even getting a once in awhile batch of e-mail, I can't send anything at anytime. I don not have a problem going to Earthlink.net/webmail and reading my mail there, but it is not always easy to do this.....thus Thunderbird!!

Thunderbird is up to date.

server: pop.ix.netcom.com on port 110 connectin security as None

Encrypted password checked.  

My outgoing server is amtpauth.earthlink.net port 587 authentication method: Encrypted password connection Security None.

All of this has not changed since mozilla made changes years ago and they are the same settings that are reccommended by Mozilla Thunderbird for the ix.netcom.com people. 

I sure have to have to move to another progam, but I can't keep putting up with this. Hopefully someone can help!! I've added images of my settings and also of the error message I get when trying to send mail. BTW We had about 5 sessions with the India help desk at which we kept getting cut off. When finally getting to chat with someone....they had no answers, they said they would esculate the problem and someone would call in 24 hrs. That never happened...The case ID # 203683399 NO ONE EVER RESPONDED and so the problem persists.

I am having trouble sending emails. I receive a message saying "The message could not be sent because connecting to Outgoing server (SMTP) smtp.optusnet.com.au 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 am not aware that I have changed any settings. I can receive emails okay but have not been able to send them since 12 January 2025. Please help.

I didn't know there was a non-ESR version of Thunderbird until I found out by chance a few days ago! Since the latest update to ESR 128.5.2 has crashed 11 times this week, I would like to move to the latest version (64 bit?) non-ESR. There must surely be an official Mozilla step-by-step guide to doing this?

Ever since my latest upgrade my email will not connect I keep getting, could not connect to serverpop3.optusnet.com.au the connection was refused.. I am running windows 10 system..

I was recently upgraded to Ver 128.6.0esr (64 bit) and I am not a fan of this version due to a number of concerns. Although a long term user of Thunderbird, no doubt my problem/s will be 'user error'.

I started off today hoping to put a stop to my New messages from being deleted automatically, even before I get to read them. (Seems to be a big concern and area of frustration with many MT users) Having just changed over from POP3 to IMAP (sick of losing msgs off the server) and following ALL instructions I seem to be going around and around without any +ve results or changes. Mind you this is the 3rd day now and cannot afford to be messing about as I have a business to operate.

First Problem - Re: stopping messages from auto deletion Action #1: I goto >Local folders> Disk Space and select ....'Don't delete any messages' Action #2: I goto >Sync & Storage>Message Sync>'Keep messages in all folders for this account on this computer' RESULT: No change. New messages go straight into deleted folder and are highlighted.

Second Problem - Stopping auto Compaction by Following instructions on Mozilla Help page Action #1: I goto >How Can I Configure Compact? Action #2: Select Preferences (formerly Options)>Network & Disk Space>Disk Space Action #3a: Cannot find Preferences Action #3b: or Options

Following instructions for Step #2 I open Application Menu as detailed and GUESS WHAT?.... 'Select Preferences (formerly Options)>Network & Disk Space>Disk Space' is nowhere to be seen.

I am wondering if anyone in the Thunderbird Tech Dev section has ever bothered a) Read and b) follow the instructions given to see if they actually display as described and then work.

Anyhow, can someone give me a straightforward reply and resolve to this matter as I am considering leaving MT and finding another agent that works as it is supposed to?

Thanking you in advance for any assistance.

Phil

A windows update failed. Once I had resolved the issues and successfully installed the update, I went into the Thunderbird Inbox folder, to find only unread messages were present. Checking other folders all seemed well. When I search I can find one example of a read message saying it is in the inbox, but I can't see it. I attach images of the search results and my current inbox. Any ideas how to get the missing read messages back?

All the messages in my Inbox disappeared this morning. I have a MacBook Air running Sonoma 14.7.2, my ISP is Gandi, and Thunderbird 115.4.1 is my email. I had clicked on a link in an email from a known source and when I returned to email, all the inbox messages were gone. All other folders (Sent, Drafts, etc) are there and current. My husband and I each have email accounts; his Inbox is all there too. The Inbox emails were not in the Trash, Deleted or Junk folders. I closed Thunderbird and reopened; messages still gone. I closed all apps, shut down the computer and restarted; opened Thunderbird, messages still gone. When I look at the Profile files, I can't tell which one would be my Inbox, but none of the likely candidates seems big enough to hold the, um, 7000+ messages that were there. I have spent the day internet-searching and reading various posts on disappearing messages - most of which are very old and/or for Windows - but I am unable to figure out what to do. Are the messages somewhere in the Profile? Are they on my ISP's server? How can I get them back into the Inbox? Thanks for any help.

Cannot access email.

Went to email provider website and all emails are there.

Reset password and tried to update Thunderbird. No success.

Using POP account. Can get Thunderbird to hold all information. But when it tries to login to server says it cannot. This started 2 days ago. Also email from another different account ( IMAP) is painfully slow. Thunderbird says it is fully updated. Thunderbird often goes into not responding spinning wheel.

server is mail.(server).com pop puts it at 995 port, email carrier (Spectrum) says should be SSL on but choices are only TLS/SSL or STARTTLS what to use, also should password be used.

Hi, I'm not able to open jpg files which are joined in a message. When I want to, I can't find the default application Photos in the choice menu (see the images). I have installed the "visionneuse de photos windows" which replaces the default application Photos for windows 10. I think maybe it is the source of the problem, but I can't find any solution to open images whithout saving them in my computer. I don't understand why the "Photos" defaul application doesn't even appear in the choice, while it is still installed on my computer.

Is there anybody who can help me ? Thanks !

I am getting stopped, dead cold, every time I try to install Thunderbird mail on Linux Mint 22. I've attached a generic article that explains how Akamai's site security services bots are working to protect a site or sites that TB must access to complete it's installation task. In my case it's Comcast/Xfinity. Accordingly, TB installations will not complete and new users are locked out...some for months. The concensus of the devs that have been working on this critical issue is that there is nothing on a new TB user's side that in any way causes or contributes to the issue. I would very much appreciate any information you can provide about a speedy resolution in the works.

Note: The error notification screen "Access Denied" is the same message I get, but with Xfinity referenced.

Thanks. Wiley Oregon, USA

I have successfully signed into a Matrix chat and there was a list of messages I could read. But in most later Thunderbird sessions, the Window stays emtpy although in the bottom right corner of the screen popup windows with Matrix messages do appear. In the left pane the rooms I have entered should be displayed, but they are not. When I re-enter a room by hitting the button and re-typing the room's name, the list of joined chats, consisting of this one, appears in the left pane for the fraction of a second. I don't see any item in the config options for chat where I could have screwed something up.
