I was able to access my Yahoo email with Thunderbird by using the OAuth2 authentication method. However, I am not able to send a email using the yahoo outgoing server. There is no selection for OAuth2 for the outgoing server. I get the message "The message could not be sent because connecting to Outgoing server (SMTP) yahoo failed." What do I need to do to be able to send email via yahoo?

In the past week or so (since the holidays, perhaps), meeting invites I am getting are not converting the time correctly. I can make it work by manually editing the ics file and changing the first TZID from America/Chicago to US/Central I. The screen SHOWS the correct time (image atached) , but it imports as it the time was UTC

If the DTSTART and DTEND are set to US/Central it doesn't work. The issue is it would seem that the user is creating these with the webmail version of Rackspace email, which he has done for YEARS with no issue. Did something change as of recent that would make this format no longer work?

I have to export every one of his meeting invites (and several other people not using rackspace) and make that change at the top to make this import correctly.

Using IMAP deleted items remain greyed out. Have tried all suggestions: emptied trash, repaired inbox, checked subscriptions, set expunge. Nothing worked. Am I missing something? All help appreciated. Don't think AOL server is removing the deleted items.

I sent a request for help and got this response:

"Well you might start by actually advising what the error is. We are at this point left to guess what "When launching Thunderbird, I get a pop-up saying Server "outlook.office365.com" reported en error" means and I can assure you it is not much to base a guess on. What is the message verbatim?"

You missed the point entirely! The point is that there NO ERROR CODE REPORTED, only the cryptic information I sent earlier. Further, if I knew the error code, I could fix it myself. The question is whether there is some kind of a log file kept in Thunderbird that may shed some light on the problem. Hopefully, now you understand the problem and can respond in a more meaningful and professional manner.

Some additional information: (a) sometimes email does not send, (b) I have already reinstalled T-Bird with with the mystery error continuing, (c) no errors were reported during installation. If there is no log file that T-Bird keeps and if you have no way of helping me track this down, T-Bird has ceased to be a practical alternative to Outlook.

Hello,

I run Thunderbird 146.01 under Windows 11 Version 10.0.22631 Build 22631... TB pulls messages from a POP Server.

Though I have tried many fixes TB keeps reverting to requiring that I manually run both Spam Sorting, and Filter Sorting, usually after running these functions automatically for about a week.

Might someone suggest a fix that will have some lasting benefit?

Many thanks,

Lothar

Hi. Somehow, in Thunderbird Mail, I moved the "Bulk" folder into the "Trash" folder and now I can't reverse that. Some of my mail is going to the "Bulk" folder and I'm forgetting to check that, thus missing emails. Is there a way to move that "Bulk" folder back where it belongs? thanks in advance

Hello! I have a bit of a long story but hopefully this won't take too much of your time. I have a windows 11 pc that came with a realtively small ssd. I installed thunderbird and used it for many months. then i cloned this ssd to a new higher capacity ssd and installed the new ssd into my pc. i continued with thunderbird and my new ssd for roughtly 3 months but i found that the new ssd was glitching and was giving me problems.

about two weeks ago i removed the cloned high-capacity ssd which had the three months of new emails and i reinstalled the old original ssd into my pc and have continued with thunderbird. i also installed the glitchy high-capacity ssd into a docking station and i have it connected to my pc as an external drive. So my problem is that while my pc has all my original thunderbird emails, it is missing the three months of emails that are on the cloned high-capacity ssd. And to further complicate things, i have been using my reinstalled old ssd for two weeks and have accumulated new thunderbird emails.

how can i copy or import the three months of thunderbird emails that are on my high capacity ssd that is attached to the computer now as an external drive. Remember that not only does that high capacity drive have three months of emails that I need, it also has all my original thunderbird emails that it obtained through the cloning process. so my concern is that whatever import process i might do, it is either going to cause a lot of duplication of the old emails or it is going to wipe out or disturb the most recent activity (my last two weeks) when one profile is replaced entire replaces another.

MY QUESTION: is there a way to selectively import just the last three months of my thunderbird emails from the high capacity ssd that is connected currently as an external drive? I know the specfic date range that i am looking for.

thanks eric

For as far back as I can remember I've been using Mozilla Thunderbird on a old computer running Windows 7. I've a Win10 machine here so a few months ago, I downloaded the latest Thunderbird and I was suprised to see it looked very different. After a bit of experimenting I managed to get it looking familiar so I uninstalled it with the intention of trying it again early in 2026 when I've a bit more free time, So this morning I installed the latest version but it looks even more different now :-(

I'm not sure how to attach images here but if it works, the original one looked like Capture01 and this morning's one is like Capture02. I still had my installer from a few months ago so I installed that one and it looks the same as today's one. Notice that there's no menu bar any more and AFAICT I can only view email headers and not their contents. Also, the 3 boxes at the top RHS (for sizing the window / minimizing it etc) don't work at all.

Is it me doing something wrong - or are there maybe some settings somewhere that I need to experiment with?

When I let thunderbird compress the inbox and other folders, the not read flags on all new emails get reset as if I have read all of the new emails. Compressing the inbox and other folders should have no effect on the flags showing a message has not yet been read. That only makes sense. The not read flags getting reset started happening several versions before 145.

I have had my @yahoo.ca email for many years. I have always used Thunderbird to retrieve my email and read it locally on my desktop. Recently when Thunderbird launched Rogers take over and wants me to lo in to rogers. It is not a Rogers.com email address, it is a yahoo.ca email address.

Why has Rogers taken over my email.

I can still access my email on the web at the yahoo.ca website, but I want it back in Thunderbird as well.

Been getting a bunch of this, usually in my TB TRASH folder, I think from the Outlook online server.

The server couldn't retrieve the following message:

Subject: "<Removed for PII>"

From: "Not available" ("Not available")

Sent date: 10/31/2024 2:25:02 PM

The message hasn't been deleted. You might be able to view it using either Outlook or Outlook Web App. You can also contact the sender to find out what the message says.

I have 2 personal email accounts: Outlook and Gmail. My client is Thunderbird. Running Win11 25H2. Far as I know, problem began recently. This is a screenshot of some messages from TBirds TRASH folder.

User's image (In images) Thunderbird just tried to fetch emails. Got a notification that it could not get messages, this time from GMail.

What does this mean? Outlook/Gmail servers or Thunderbird? What do I need to do?

Have been forwarding all my AOL mail to Thunderbird for years without problem.

About 2 wks ago, email with attachments stopped being forwarded. Emails without attachments are forwarded without problem. AOL says nothing changed on their end although I noted that the "Forwarding" tab no longer appears on their mail choice menue.

Why are older emails disappearing from the Inbox? It didn't do this when I was using Windows 7SP1. Now I have Windows 11 and it seems the Oct and Nov emails I had have disappeared. Only Dec emails are in the Inbox.

Hi all, I'm experiencing persistent and reproducible segmentation fault crashes with both Thunderbird (versions 140.0.1, 141, and 142 tested) and Betterbird on Arch Linux. The crashes occur consistently within 30 seconds to 2 minutes of operation, making the application unusable.

System Configuration:

• Arch Linux (fully updated)
• KDE Plasma 6 on Wayland
• Multi-monitor setup using DisplayLink/evdi drivers
• Firefox works perfectly fine (no crashes)

What I've Already Tried:

• Fresh profiles (completely clean - crashes persist)
• Safe mode with add-ons disabled
• Disabling hardware acceleration (MOZ_DISABLE_RDD_SANDBOX=1, --disable-gpu)
• Software rendering mode
• Multiple Thunderbird versions (140, 141, 142)
• Alternative client (Betterbird) - same crashes
• Full system upgrade

All crashes show the same signature in libxul.so during startup/operation. The stack traces consistently point to Mozilla's threading/compositor code. Notably, Firefox using the same libxul.so library works without any issues, which suggests this is Thunderbird-specific.

I believe the issue is related to KWin compositor interaction with my multi-monitor DisplayLink (evdi) setup on Wayland. The crashes are specific to Thunderbird/Betterbird and do not occur with Firefox, despite them sharing core libraries. Note that this problem happens on both x11 and Wayland.

I have extensive coredumpctl output available if that would be helpful for debugging. Has anyone else experienced similar crashes with multi-monitor setups or KWin/Wayland compositor issues?

Any assistance would be greatly appreciated!

I use a work email server outsourced to office365.com and Thunderbird v115.18.0 (64-bit).

I connect using Thunderbird with IMAP, and am subscribed to 100s of my folders there.

I reorganized my folders there, moving them about using THUNDERBIRD (not, as I've learned now, using the Outlook Web interface that I "should" have used). Needless to say, I was only moving subscribed folders about.

Now I find that the subscriptions to folders which have been moved or even deleted cannot be manipulated. Folders with the same name but now in different hierarchies can't be subscribed to.

I have removed the account, recreated it and Unsubscribed from EVERY FOLDER. But the erroneous subscriptions do not go away.

I have been having trouble for awhile now with the preview pane not changing with a message archive, delete or even a new message arriving. The only solution I have found that works is to turn it off/on with F8. Have tried updating (currently on 140.6.0esr), unified folder debugging, and setting thunderbird to download complete message not in bits on AI suggestions. Doing same thing on laptop and desktop. Gmail, yahoo and outlook accounts. It seems to only happen when using the unified inbox folder. Cannot find any reports here in forums, but AI says it is a common complaint. Is there anything I am missing to try?

Discovered no mail download ( auto or manual) into tbird fm Jan1st, ( 146 updated mid Dec)

As others already reported eventually determined due some interaction with email virus checker (AVG) HoweverTbird not useful or helpful in providing to user any indication of problem or providing failure info.

Issue showed as 'Get email' not doing/showing anything - not showing pop3 login+download steps or anything else.. - saw one timeout popup wdw but usually nothing..

Error console showed an error message that "pop3 socket closed will not send info".... fine sfaigoes but have to go look for it.

Downgrade tbird version (145) even tho 146 working for 2 weeks before stopped) - same issue/problem (as per error log)

Direct access to server showed server end closing socket due multiple concurrent sockets open, indicating tbird and AVG.. reset AVG and reboot and restart and (145) now loading but....

Issue is that tbird should be presenting some failure indication to the user on socket connection failure ( wdw popup or message line status - where shows 'making connection";, "login, ...It doesnt show anything... so silent failure.... Just doesnt work ...

Unrelated but should also mention that error console display of 146 prior to above 'pop socket close' msg also shows failure of verification of a tbird extn due missing manifest file... There was only one extn in the extensions dir so Its that one (supplied with 146 installation) - clearly named with a random collection of alphanumeric and hyphen chars...

Cheers

I have installed Thunderbird with Zorin 18 and it won't show contacts. Google says that Thunderbird has full access to contacts. Attempt to manually add contacts fails with message of "Can't connect to server". I did have to manually add the calendar to make that part work. Is this an uninstall and reinstall (Thunderbird that is) situation?

Thanks for your help

I have a laptop that updated itself and is now updated to the latest version of Thunderbird. Desktop computer is still on v.115. I have the Local Folders on the laptop set to use a shared folder on the desktop and locally store incoming emails on the laptop. I use the shared folder for archiving emails on the desktop. So LaptopMail is stored on D:\LocalMail on the laptop and the Local Folders is set to store files on the desktop through the private local network on a shared folder (D:\Mail-Common on the desktop hard drive) Up until today this worked almost flawlessly. When things do go sideways on an update (which happens with thunderbird more than I like) I ususally search for an answer first. Normally, I find an answer that works.

The problem is exactly as was in this post [ https://support.mozilla.org/en-US/questions/1512216#search ] The fix however didn't work for me. I cannot directly edit the Local Directory path either. The browse button still works though. Currently, D:\Mail-Common is mapped to the "N:" drive and all that is in the Local Directory path in the Local Folders settings is N:

Any more suggestions are more than welcome
