Whenever I try to delete or edit single instances of a recurring event in Thunderbird, it looks like it is gone, but if I close and reopen Thunderbird, it reappears. This happened only recently. I am using Thunderbird 115.11.0 in Linux Ubuntu 24.04. Please advise.

I can't get smtp to work with multiple yahoo accounts. When I get the account settings window, it shows the correct smtp server for yahoo. (smtp.mail.yahoo.com) but when I click on the edit SMTP button, there is a section called "Security and Authentication" section with 3 lines

     Connection Security:             [SSL/TLS]
     Authentication Method :        [0AUTH2]
     User Name:                             [*****1@cox.net]  (My accounts were transferred from COX to Yahoo)

If I edit the SMTP on any of my cox accounts, it changes them all to the same user name. If I want to send mail from any cox account, I have to go to account settings first and edit the smtp and put in the correct account. This is very tedious.

I have noticed that my gmail accounts do the same thing, but gmail doesn't care. Here is the error I get when sending mail before going to account settings first to change the account.

Sending of the message failed. An error occurred while sending mail. The mail server responded: Request failed; Mailbox unavailable. Please verify that your email address is correct in your account settings and try again.

I am running 115.11.0 on Ubuntu 22.04

I changed email SMTP servers, incoming and outgoing. First I migrated IMAP on the cloud between old host and new host. I connected Thunderbird using existing a profile, just changed server information. After that email started coming into Thunderbird. I discovered a bunch of the filters had been disabled with no destination folder. Not all of them. Just maybe half. It knew the destination folder for the filter because it was at top of window when I would look at filter rule. I had to use that as guide as to what destination folder it should go to, and it filters fine.

Why were all these filters cleared of destination folder?

Hyperlinked text does not paste into Thunderbird email. Only the text pastes in. The hyperlinks do not. If I paste in text that has several hyperlinks already embedded only the text pastes in. The hyperlinks are lost. I must paste the hyperlinked text with the URLs. How do I do this. All searches are irrelevant. I know hot to insert URL into new text but that is not the issue. My text to be pasted already has many hyperlinks in the text and I do not want to laboriousness do them all again. When I paste in a paragraph of test that already has several hyperlinks I want that ALL to past in. How to I do this?

When I try to download messages on one of several POP3 accounts I get the error message Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox. and it keeps downloading the last message I received before the problem started.

I have tried repairing the folder, clearing cache and even turning off my anti-virus for Thunderbird but to no avail. No problems on my other accounts

Good morning,

I can't deactivate the dark theme (the Themes Menu is inactive!), while another user has a light theme and works perfectly.

In addition, the writing of new messages is in white text on a white background!

How can I solve this problem. thank you in advance for your help

Cordially

I use a Google Workspace account in Thunderbird. I have six main folders and each has sub-folders. I create search folders for each and favorite them so they’re across the top in TB. The individual emails then show up in each and I can chose to only show the unread ones. As far as I know TB is the only email program to allow this and it’s great. Recently I’ll be working away, pleased that I’m not getting inundated with emails, only to find out that I’m missing bunches of emails because the folders aren’t updating. I can open the individual folders and they’ll download new emails, which will then populate the search folders, but not getting to emails in a timely fashion is a problem. Anyone know what’s going on? TIA.

My @gn.apc.org (IMAP) inbox has a limited capacity to display, to keep important email. They simply drop-off the list. It currently saves only today's emails. This cannot be correct. I have attached a timeline. Appreciate some info & advice

I use Thunderbird for mail.cablespeed.com email accounts as well as a gmail account. The last few days all outgoing messages on the cablespeed accounts do not go, instead I get this error message:

Sending of the message failed. An error occurred while sending mail. The mail server responded: [VO-1] Message blocked due to spam content in the message.. Please check the message and try again.

What is happening? What can I do about it? Tech support (such as it is) from Astound Broadband, the current owner of cablespeed, says that they have ended the use of all 3rd party email clients...without notification. They want me to use their web email. My contacts are on Thunderbird, my email folders are on Thunderbird. What a headache. The gmail account works as it should on Thunderbird.

This is new. What can I do?

"Please verify that your Outgoing server (SMTP) settings are correct and try again." I've tried every combination and still can't send emails. Optus insist that their issues have been resolved. Please help.

I permanently deleted all messages in a folder (call it "Unwanted"), then moved Unwanted to Trash, then deleted it permanently. It appeared to be gone. However the next time I opened Thunderbird, Unwanted was back. I tried this several times with the same result. I tried renaming it to "DeleteMe" but then I got the message "The folder could not be renamed. Perhaps the folder is being reparsed, or the new name is not a valid folder name."

Once again, I "permanently" deleted Unwanted and closed Thunderbird. Using a file manager, I found and deleted all relevant folders and files matching "Trash.*" and "Unwanted*.*" and rebooted the computer. However when I opened Thunderbird, an empty "Trash" folder was regenerated as expected, but the "Unwanted" folder was back.

How can I get rid of Unwanted? Thanks!

Several times lately I click on an email from cnet and it will not load. The reason is when Thunderbird passes the link to Firefox there is an extra https// added to the beginning: https//https//cnet... . Not all email links from cnet start with https//, but when they do I must manually delete the first one (in Firefox). Not sure which program, Thunderbird or Firefox, is causing the problem, but it is annoying.

Hello, I recently installed Ubuntu 24.04 with the version of Thunderbird (115.10.1) supplied with the distribution. I can no longer display mail saved as .eml in a remote folder (sftp). Thunderbird opens, but the mail window is empty. If I ask for the source code, this message appears:

Unable to read file at address view-source:file:///run/user/1000/kio-fuse-ouSeRu/sftp/myuser@myserver/mymessage.eml?type=application/x-message-display.

If I open from CLI I get this message :

JavaScript error: chrome://messenger/content/aboutMessage.js, line 218: NS_ERROR_FILE_ACCESS_DENIED: Component returned failure code: 0x80520015 (NS_ERROR_FILE_ACCESS_DENIED) [nsIMsgDBHdr.mime2DecodedSubject]

If I open the save file with a file editor I'm able to see the source code.

Could you please help me? Thanks

I am currently using T-Bird 115.11 on Windows 10. Not that it matters much, because I have had this problem continually for years with various editions of Thunderbird on Win7 as well. Often when I open Thunderbird, I discover it has created hundreds and even thousands (today 65,000) duplicates of emails in various mailboxes. This has nothing to do with downloading. The emails in question were downloaded weeks or even months ago, and I havev't accessed them. Another problem is that Thunderbird creates emails dated in 1970, even before anyone thought of the internet, let alone PCs or emails. Why is this happening? How can I prevent it?

this interface uses pop3

When emails are pulled, I can see that it pulls, let's say, 50 messages, the notification shows 25 new messages but the inbox only shows 10. I have looked everywhere for the "missing messages" but don't see them anywhere. I have also had some people tell me that they sent an email response (so they were not entering the email address) and I don't see it.

What could cause these differences?

My email for my domain (Gailfisher@Resourcesforchange.com) hosted by GoDaddy. Has been working correctly for years, but now when trying to send from TB, I get a message to enter password that does not work (it does work on my webhost's platform). Using Windows 10, TB version 115.11.0. BTW, I have another email via AOL that is working just fine on TB. I tried Safe mode -no go I tried following GoDaddy's instructions for IMAP but also did not work. FYI The GoDaddy help desk said: "Please match the server settings with the below server settings. Username Your email address Password Your email account's password Incoming servermail.[your domain name] Incoming ports IMAP - 143 POP - 110 Outgoing servermail.[your domain name] SMTP (outgoing) ports25 (587 or 80 might also work) IMAP use port 143" I tried setting up a new account in TB using email adddress and a new username, but that created the same problem. Here are the relevant screenshots. Thanks for your help!

Hello! I have tried to install the normal Thunderbird on my PC for months now. Everytime all it does is count more and more files, folders etc. I can't get it to install. The two screenshots were made within a few minutes. I let it install for around an hour one time and it simply counted more and more files without ever moving in progress. I really don't know what to do. Restarts, redownloads, nothing works. Maybe someone knows what's wrong. Thanks!

Hi, just upgrade to Windows1 and did a new installation from Thunderbird. latest version 115.11.0 (32-bits) But the new messages are almost directly market as read even with setting mark messages automatic as read set to no? On a other pc with Windows11 I had the same problem with the 64bit version but going to the 32bit version solved the problem. Any Idea how to solved this problem? Regards Karina
