My aim is for the e-mail icon to appear first at the top of the sidebar, then the calendar and then the address book. The default setting is e-mail, then address book, then calendar. Also, I would like to hide the chat icon completely. Is there a solution for this? Gladly also via userChrome.css...

For the past few days I have intermittently had a problem sending email. I get email from Spectrum, my ISP. When I try to send I get this message: Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: p-impout007.msg.pkvw.co.charter.net cmsmtp 173.211.127.45 blocked. Please see https://www.spectrum.net/support/internet/understanding-email-error-codes for more information. AUP#Out-1130.

When I go to the indicated website and look up error 1130, this is what I get: The IP address you’re trying to connect from has an issue with the Domain Name System. Spectrum requires a full circle DNS for emails to be allowed through. Verify the IP you’re connecting from, and check the IP address to ensure a reverse DNS entry exists for the IP. If the IP address is a Spectrum-provided email address, contact us.

Note my email address is not Spectrum provided.

For years I have used the extension 'Calendar Tweaks' because it colorizes the entire event in the calendar. This extension is no longer compatible with versions of Thunderbird after 74 so I have stop updation after Version 69. However in resolving problems with authorization I needed to update to the current Version of Thunderbird so my events in the calendar now just show the category color at the edge of the box instead of the entire box. Is there a way in Thunderbird to colorize the entire event box or another extension that does this.

In my Linux installation, there is a folder /home/.thunderbird/<account name>/Photos It contains many small images of people in jpeg format. They have name similar to 69c143ed0a9180b5_1551971368866.jpeg or d36fef86-48fb-4fe5-b036-a42676e2e39f.VALUE=URI-JPEG. I do not know from where these files come, nor what purpose they serve, nor if they can be deleted without creating any problems. In particular, I would like to know if the creation of files in that folder can be disabled. If so, how? If not, can they be deleted without creating any issues?

Have been using Thunderbird for a long time with a gmail and an Outlook account. (Outlook recently created problems in Tbird and in both mobile apps that I use and I want to dump it!)

I created a Mailfence account today - the free version. Tried to add the Mailfence account to Tbird. There are posts in this forum saying Mailfence doesn't allow imap / smtp access if you only have the free account, and there are posts saying it's allowed during a 2-week trial. Does anyone know for sure? On the Mailfence site, there seems to be no way to find the necessary settings, and every time I try to set it up (whether automatically or manually) the Mailfence account refuses to connect. So I suspect those who say you have to pay are correct.

I got an email from Microsoft saying my Live.com or Outlook.com email accounts won't be supported in Thunderbird UNLESS I change the settings to OAuth2 in incoming and outgoing server settings.

I even REMOVED the email account and re-added it making sure it was OAuth2.

But for my live.com & outlook.com email accounts I continually get prompts for passwords from Thunderbird. Sometimes I can't even click the RED X at the upper right to shut the prompt down. I just happens over and over until I give it what it wants.

I am tempted to shut down all Microsoft email accounts and switch to Gmail.

I have Thunderbird version 115.12.2 (64-bit) I used Windows 11 23H2 build 22631.3810 Windows Feature Experience Pack 1000.22700.1020.0

Any idea how to stop these prompts?

I like Thunderbird much more than any other email program I have ever used, and would like to keep it

I installed Thunderbird and typed in my Office 365 email information to connect my account. Thunderbird found the correct IMAP settings, which I verified on Microsoft's website. It proceeds to open a browser so I can authenticate my account. After that succeeds it starts downloading all of my messages & folders. I thought everything went fine until I attempted to send a message. I get the following error:

Login to server smtp.office365.com with username me@mydomain.com has failed.

It gives me the option to enter a new password, which doesn't make sense since it's oAuth2 but I created an app password to see if that would work, and it didn't. The only other options are cancel & retry which don't help either.

I thought maybe something went wrong with the authentication process so I uninstalled thunderbird and started again with the same results. I've tried many other server settings, but nothing works, so I'm here.

Current Settings:

Server Name: smtp.office365.com User Name: me@mydomain.com Authentication Method: oAuth2 Security: STARTTLS Port: 587

I've tried: Using Port 465 / SSL/TLS Using Port 465 / STARTLS Using Port 587 / SSL/TLS Changing Auth method to Normal Password and then using app-specific password. Uninstall / Resintsall

One final thing to note: I followed the same process with my fastmail.com account, which worked flawlessly. I can send & receive fine.

I have 4 accounts with different names but all with the same domain name (name1@samedomain.com, name2@samedomain.com ...). The first one set up perfectly and works. The 2nd and the 3rd can't retrieve mail from the server (didn't try the 4th yet). The SSL ports are the same for all. The passwords happen to be the same for all. (I haven't tried changing the 2nd and 3rd passwords as that seems unlikely to be the problem.) When initially setting up the 2nd or the 3rd I get a "Sending of password for user name2@samedomain.com did not succeed. Mail server pop.yyy.zzz responded: [AUTH Authentification failed." I've checked the passwords on both the client and the server ends multiple times and they are the same. Then, of course, periodically I get a pop-up with "Login to server pop.xxx.yyy with username name2@samedomain.com failed. When I go to the Account Settings screen with the 3 accounts and click on each Server Settings one after another, the only thing that changes is the User Name, yet the first account receives mail and the other 2 don't so everything is correctly set up. As an aside, I CAN SEND emails from the 2nd and 3rd accounts but can only RECEIVE and SEND from the 1st. Any help appreciated.

My Thunderbird messages screen buttons now has a new button named "RWH" and when you click on it, the choices are "Enable for 10s" or "Enable or headers for 10s". I search the Help file for RWH and 10s and found nothing? What is RWH and 10s? What do those two choices do?

Hi

 I am using version 115.14.0 (64-bit) and I am using Fedora 39, up to date OS.  I have been using ThunderBird for a very long time.  I have been experiencing an issue which, unfortunately, seems to come and go.  I am experiencing this issue on 2 separate physical computers.  How can I restore the list of emails under any account when they are not visible?
 This is very troubling ...

Robert

With 128, it appears you guys have taken away the ability to choose where our signature should be placed, as we could in 115.

Can you advise how I might get this functionality back?

My reply Signature

Original Quoted message

It makes no sense to me to have a signature below the quoted text.

Thank you

Before the last update, when you assigned a colored label to the message (e.g., work, important, etc.), the entire title, header of the message, took the chosen color. Now you only see a small tag.

'The previous system was definitely more practical. Can it be reactivated?

This just happened with a new update on only one of my two gmail accounts 128.2.3esr

I was not getting email on one account, so I deleted that one account. Now I can't add it back to TB. I get "Unable to log in at server. Probably wrong configuration, username or password." Double check password and logged on with it on Edge browser, no problem.

I uninstalled / reinstalled Thunderbird with the same result.

Thank you!

Think this is a bug report rather than a question.... anyway....

In case you don't know....

mbox files store emails with "From " on a new line recognised as the beginning of a new email (and thus the end of the last).

There are various formats, but a typical first line will be something like From - Fri, 20 Oct 2000 11:34:32 (sometimes the sender name is included here, sometimes the date format differs, probably due to history of client used, sometimes there's no dash; the actual information is still available in various other headers)

The problem is.....

When moving emails from one folder within Local Folders (I haven't tested imap folders, but that's not what I need), the information is stripped, leaving only "From " (followed by new line). The remainder of the email is fine, and moving folders whole retains all information.

I've tried drag and drop, and I've tried "Copy..." dialogues. I've tried message filters. I've also tried a couple of extensions (I presume they just use the built-in file moving code). All exhibit this behaviour.

(for info, I'm trying to rebuild my archive in a logical way from zillions of backups, and for whatever reason this behaviour spoils the ability to remove duplicates via the "Remove Duplicate Messages" add-on, which does cope otherwise - I'm trying to merge multiple folders from maybe 25 years(!). I haven't even started on my Outlook .pst archives!)

(Bonus - another one, which may be intentional - when moving emails from one folder to another, the source mbox file keeps all the moved emails, and only its .msf index is updated. Go to "Properties... Repair Folder"; the .msf is recalculated and all your moved emails reappear magically.)

Basically things work under the hood, but it's all a bit flaky.... ;-)

Anyway, thanks, and do as you will with all of this!  :-)

Message filters not working after transfer to new windows device. (Apologies for long report below). Problem is similar to that reported and still unsolved here: https://support.mozilla.org/en-US/questions/1391209

All old messages automatically accessed under IMAP protocol sit within correct email folder on new device.

Message filters rules successfully located on old device, copied and placed in corresponding windows folder on new device. Email folder structure looks identical on both devices.

New messages sit in inbox on new device, without being filtered. Instead error messages appear, repeatedly.

"The folder 'xxxx' could not be found, so filter(s) associated with this folder will be disabled. Verify that the folder exists, and that filters point to a valid destination folder.

The folder 'yyyy' could not be found, so filter(s) associated with this folder will be disabled. Verify that the folder exists, and that filters point to a valid destination folder.

If same new messages are accessed on old device, they later appear in correct folder on new device, and no longer sit in inbox

How to make email folder structure on new device visible to filter rules there ? This is necessary for filtered email to work successfully on new device, without requiring old device to be operational - it will be taken out of service in near future.

I'm used to tagging important messages by right clicking on the message and with my left hand clicking G and 1. Quick and easy.

As of the latest update, that no longer works. After typing the G, I need to remove my right hand from the mouse to press the [Enter] key before I can complete the process by typing 1. It’s not a super' 'big deal, but it does slow me down — and I get annoyed because I haven’t unlearned the old pattern yet and forget to hit the [Enter] key almost every time I try to tag an email.

Can this change be rolled back?

since 8/22/24 I have been unable to send email from one of my personal domains. Same install of T-Bird successfully sends SMTP via Gmail and my other domains.

I receive the error shown in the first photo below. Sending of the message failed. An error occurred while sending mail. Outgoing server (SMTP) error. The server responded: us2.outbound.mailhostbox.com ESMTP not accepting connections.

I have been back and forth with the domain tech support. Here are the email content (parsed for easy reading)

Me > I am having difficulty sending email. > I can POP email without issue. > I am using the most recent version of Thunderbird; version 128.2.0esr (64-bit) > When I send (with or without an attachment) I get the following error: error as shown above > I have never seen this error before and cannot find it in your knowledgebase files. > My SMTP settings: > > server name: smtp.drachenfelspress.com > Port: 587 > Connection security: None > Authentication method: Password; transmitted insecurely > User Name: mcaputo@drachenfelspress.com

Tech: If you are able to download emails from our server but unable to send out emails through the same, then it is likely that your Internet service provider is blocking port 25 on your local network. For such ISPs, you must use their SMTP server to send out mails on their network. Customer Support - TH

WELL Since I was using 587 that didn't help at all.

ME the error says YOUR server, "US2.outbound.mailhostbox.com ESMTP not accepting connections." This is YOUR error, not my ISP. I was using port 587, my ISP does not block port 25.

Tech try non-SSL using the following: STARTTLS Auth Normal change server name to smtp.<yourdomain>.com

Me No change

Tech Try reducing TLS version back to 1.0

Me No difference. Restored TLS 1.3

Tech return to the mailhostbox.com server Port 587 STARTTLS Normal full username

ME ok, no difference. That is where we started, didn't work then, doesn't work now. (second photo)

Tech Try port 25

ME Same results

Tech <resets my password>

Me Did you reset my password overnight?

Tech To investigate the issue, we needed to reset the password for mcaputo@drachenfelspress.com, to enable us to configure the Thunderbird email client on our end. The temporary password is "Se!!P)iqk2" We have successfully created a Thunderbird account and were able to send emails through it without any complications. The configurations we utilized are displayed in the screenshot provided below: us2.outbound.mailhostbox.com Port 587 STARTTLS Normal full username

Then change your password.

Me I appreciate your response. HOWEVER the issue remains.

Tech We have already replied to you on this matter.

ME Tried sending on port 465 and it indicated "sending" but hung there. Using Telnet I am able to access the us2.smtp.mailhostbox.com on port 587 but I cannot trigger an AUTH login through TELNET. (see CMD screenshot below)

Tech What is your IP address?

ME It is not static, but today's is (IP address at the time given)

Tech We have done further testing by setting the ThunderBird email client for mcaputo@drachenfelspress.com to both SSL and Non SSL connections. We can see both the implementations being fetched correctly without any issues. <provides two sets of POP and IMAP settings>

ME I can POP successfully, have always been able to. Problem is with SMTP, outbound mail.

Tech Provides two incomplete setting combinations: us2.smtp.mailboxhost.com port 587 smtp.drachenfelspress.com port 25 Upon using any of the two implementations, SSL or Non SSL as configured above, there should be no issues in setting up the email client.

The SMTP and IMAP passwords (if asked any) will be the same as your current email account password.

We are unable to replicate the issue you mentioned. Customer Support - TH

ME I am unable to replicate your success. I still cannot SEND email.

Tech We have rechecked and can confirm that we are able to setup the email client on the latest version of thunderbird i.e 128.2.1 as well using the same IMAP settings as shared in previous email. We are afraid that we are unable to replicate the issue you are reporting after numerous tests from our end. As a suggestion, could you try to connect to your mail account from a different network or ISP? Customer Support - TH

ME Again, IMAP is not used on this account the issue is with OUTGOING mail. Tried both SSL and non-SSL settings for drachenfelspress.com outgoing mail will not send.

That's ALL I have right now. I am going out right now to try to send email from a laptop with a fresh t-bird install while sitting in a McDonalds on their wifi...

Help?

My inbox messages that are incoming are showing the following message and no data. This has happened for several days. It comes from both internal and external contacts and I know the emails are not spam/junk. How do I fix it so I get the messages. It is this same code on all days and all the emails with this message. I do get some of my other emails so not sure how it is decided which this is happening to but I am missing out on several that I need due to this issue. Thanks for your assistance!

As of today, my inbox has 7,563 emails, but none of them are displayed in the messages pane. I can see them if I go to All Mail, but I'd like to be able to use my inbox.

UPDATE SINCE THERE DOESN'T APPEAR TO BE A WAY TO DELETE THIS POST - I CLICKED "REPAIR" AND IT'S NOW FIXED.
