Thunderbird Community Forum

Two nights ago I uninstalled ExpressVPN from my system at the instruction of one of their "support" people. My computer immediately lost the ability to access half of the websites I tried to visit and Thunderbird wouldn't send or receive email. I rebooted and that fixed every issue, but since then, Thunderbird no longer checks for new messages for any of my accounts. If I manually instruct it to check, it downloads the messages with no problem. I don't use any add-ons, and I'm using the latest version on a Windows 11 PC. I have already tried deleting global-messages-db.sqlite, repairing each mail folder from within Thunderbird, clearing the cache, and running an install of the latest version. I have also tried changing the setting for each mail folder to alter the interval for message checks by a minute just to see if that would jog it, but no luck. I've looked at various other help threads for this and am out of ideas. Thanks in advance for any help.

My Thunderbird has behaved very well for a decade or more. No issues and still the same. My question relates to the delete function. When I press delete I get a warning of a delete email with a chance to go back. I changed this to see what happens and now I cannot find how to return to second chance as this works best for me. Possibly simple but how? regards Replytree

This is a new Fedora-42 desktop, upgraded (dnf upgrade) today. I installed Thunderbird today (dnf install thunderbird), after doing the operating system upgrade. I tried to add my yahoo e-mail account. Settings are as follows:

• create accounts in the new Account Hub is unchecked (off).
• accept cookies from sites is checked (on).
• remember password is checked (on).
• I'm using "IMAP".

When I click "Done", a separate window pops up in which yahoo asks for my password. After entering it, yahoo says "Something went wrong", and gives no other indication of what the problem is.

If I instead "Configure manually"... I tried both the default hostnames and "export.imap.mail.yahoo.com" for the outgoing server. I tried both "Normal Password" and "OAuth2" authentication methods.

In all the above cases, I get "Unable to log in at server. Probably wrong configuration , username or password." with a yellow background.

I see nothing of "Edge Too many requests" as was happening to several people recently.

How do I add my yahoo account to this new Thunderbird on Fedora-42?

Drag and Drop attachments to the desktop stopped working again with Thunderbird 145. Steps to reproduce: You receive a mail with an attachment. You drag an attached file from this message and drop it onto the desktop of your Mac to download it. The attached file is not saved to the desktop (or any other folder I tried). This is on MacOS 26.1 MacMini M4. Please fix asap.

So I have a self hosted Exchange and I have no problems using it from apps like Google Mail, Outlook and such, plus I can login directly to its .../EWS/Exchange.asmx through a browser. However, when trying with Thunderbird 145/Linux, I always get that username or password are incorrect, but it doesn't tell me exactly what went wrong and how it tried, so I'm in the dark why it is happening. Note: exchange's url is on a different domain than my account.

Basically it's either this message: Authentication error.

Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIMsgAccountManager.createIncomingServer]

Or similar if I try to get message from inbox.

Also weird things happen during configuration, like attached image (note that I've tried different URL permutations)

TLDR; how do I diagnose the issue, or ever better, how to connect? TIA

Version 144.0.1. Unable to add a new email account. After entering the email address and going to automatic configuration... The circle keeps spinning forever... How do I add the account manually? I tested it on two computers.

I've got 2 PC, both on the same version of W11 Home and TB?

On my PC that was install in 2020, I can see on each folder and sub-folder unread mail, total mail, and size of that folder (see uploaded image). On my wife's PC, installed in March of this year, only can show the total mail and folder size?

I've Googled how to do that and of course there is no such steps I can do?

===

To show the unread message count in Thunderbird's folder pane, click the three dots icon ( ...) at the top right of the folder pane header and select "Folder Pane Columns" or "Show total message count". Some versions may also allow you to enable this view by right-clicking on the folder pane header and selecting "Folder Pane Columns," then choosing to show "Total" and "Unread".

===

Right off the bat, no "Folder Pane Columns"???

I suspect somehow this was removed from TB, so new installs this year can't get to it?

I can't even get to that on my PC from 2020 to turn them off?

Is/was there another way? Doesn't seem I have an ADD-ON to do that and I can't locate one that would do it?

Is there an answer to this or is this just the way it is (not)?

I would like to change the authentication method to OAuth2, but it doesn't appear in the drop-down menu.

My Thunderbird version is 140.4.0esr (64-bit). I have all cookies set to allow.

How do I change it to OAuth2?

MY email ISP is CenturyLink. I CAN use their WEB email site, so I know the password works. My old email had a Q.COM suffix, but CenturyLink recently said that they are abandoning that domain and that I now have to use MYCTL.NET as a suffix. I changed that in TB and now TB Fails to sign in! I have looked and looked at the TB config and still it doesn't work. Using POP for incoming email, have the correct POP server name, PORT and Encryption (SSL/TLS). I CAN ping pop.centurylink.net ....

Any suggestions would be greatly appreciated!

Thanks Nigel

I am using Thunderbird 128.14.0esr on a Windows 10 system. There were no problems until my system was shut down for 20 days while I was in the hospital. After returning home Thunderbird had lost major parts of its functionality: Problem 1-Thunderbird was unable to download the approximate 2700 email messages that had accumulated while I was in the hospital. By experimenting with troubleshooting mode and various other things I eventually got these emails into my inbox. Problem 2-When I try to send or forward a message, after a long pause Thunderbird reports that the task failed because the connection to the outgoing mail server timed out. This happens even with a short simple message to myself. If I try to save the message to the Drafts folder that also fails with a timeout. Should I update to the 140.5.0esr release? Any other suggestions?

I'd like my search results to include messages where the search item is in the Sender or Subject but it appears to find only words in the body. Is there a way to include this? btw, the window pane on the left shows a filter but I don't know how it got there or how to delete it. Is this relevant? Is there documentation on how to use the search feature to specify folders, binary searches, etc? Thanks

Hi. Ubuntu Unity 24.04 Thunderbird 140.5

When creating a New Message, the top 5 lines are missing - i.e the “End: (U)” (end time) line is displayed at the top of the screen. The only way to enter the Title of the Event is to drag the window down. Also, the Event window CANNOT be resized. This has been happening for more than a year now. Can you help? Thanks, M...

Just wondering why our forum posts can't also be black on black, or white on white, etc? Seems like the forum is stuck in the past, still doing the old black on white, as if anyone cares about being able to see the text.

I have received a new strong computer and I have now different kinds of problems. When above mentioned e-mail program was installed, my maps on left side are not in alphabetical order as it used to be. Unfortunately the installer man has not been able to sort that out. Do you have a solution I can inform him? Best regards Calle Sand E-mail: [edited email from support forum]

When I start Mozilla it checks for new mail. It always says no new mail. When I click on get messages if there are any new ones I get them downloaded. Why doesn't the first check find new mail as it used to? Thanks

I must be doing something wrong. I am new to thunderbird, migrated from Eudora since I can't send mail with Eudora anymore.

I tried to configure Thunderbird as much as possible like Eudora, but ... it doesn't receive nor send mail. On the surface it looks fine, it seems thunderbird logs into the server, it seems it sends mail and checks for new mail, only I don't receive anything, nor send anything even though it looks it does. So what am I doing (or is going) wrong? (I can still receive mail with Eudora and today I checked and received 54 mails, none with Thunderbird)

in all the years i've used thunderbird (am now on 64 bit version 144.0.1 on windows 11 25h2) the notification counter has never worked correctly

i can be sent an email & thunderbird notifies me there's 1 new email / unread message on the taskbar + tray icon

if i'm busy & ignore it / leave it thunderbird keeps on checking & incrementing that counter

when i actually download the new emails, there is still only 1 & not the number thunderbird has counted too

crazy!
