I have just starting using Thundermail and one thing I am trying to understand better is Address Books in Desktop Thundermail in Windows 11.

I now have the following under address books: All address books (assume that this is just everything in all the address books), Personal Adress Book (empty), Contacts ( not sure where it comes from, probably 1 or both of the 2 emails of mine I have connected), Contacts (not sure where this came from but looks suspiciously like it comes from my gmail email or emails? as it is a long list), Thundermail Address Book (empty), Collected Addresses (looks like it picks these up from emails I send or receive).

I am interested in understanding what forms this initial list of address books, do they continue to reflect changes in the original source address books from outside or are they a once only transfer?), how I can manipulate them, probably to end up with: All address books, and other address books continuing various subsets for convenient access to a smaller list of contacts under these sub address book names.

Can I easily copy or move addresses between address books? Documentation already answering many of these questions may already exist? Thanks for any help or advice you may be able to provide.

I am trying to add a new Outlook.com email account to Mozilla Thunderbird on Windows, using IMAP with OAuth2 authentication.

The account works correctly through Outlook.com webmail, but Thunderbird repeatedly fails to complete authentication.

I have tried the following:

1. Configured the account using IMAP with OAuth2 authentication.

2. Checked the incoming and outgoing server settings.

3. Attempted to add the account several times.

4. Checked the POP and IMAP settings in Outlook.com webmail.

5. Tried using a separate Thunderbird profile to investigate the problem.

Thunderbird does not successfully authenticate the account, preventing me from adding it.

I already have existing email accounts in Thunderbird, including an ntlworld.com account and a Hotmail account configured using POP.

My intention is to migrate my existing ntlworld.com emails and folders to the new Outlook.com account using IMAP.

Could someone please advise why OAuth2 authentication is failing and what settings or troubleshooting steps are required to resolve this?

I would particularly appreciate guidance that will not interfere with my existing Thunderbird accounts or stored emails.

I am early days learning to use Desktop Thundermail Calendars in Windows 11. I have several calendars showing up in my list of Calendars. Home, My name (seems to draw input from 2 emails I have connected), New Holiday, Thundermail Calendar, My wife's name (seems to draw input from 2 emails I have connected that she wants me to monitor as she rarely uses them). I would like to get a basic explanation of what each of these calendars are and how they may relate to each other. This may already exist somewhere? For example: what is the difference between Home and Thundermail Calendars? Why do my 2 other emails only form one combined calendar?

Example why question is being asked:

Three separate GMX email accounts, each with its own unique password, and NOW Application-specific password for Thunderbird. Aliases are not used or desired. Three different separate accounts that should each have its own outgoing server.

Worked fine until updates to Thunderbird and changes to the GMX server, and Application-specific passwords became a requirement to send and receive email.

Seems like updates to nearly every program and/or app that may be released with the intent to resolve an issue or include a new feature breaks something else. M$ is horrible with updates and labels nearly everything as a critical update so it gets pushed through even when updates are turned off or supposedly permanently disabled by a registry hack; Windows 11 being the absolute worse ever. Why I only have one computer with M$ while all the others are Linux. Problems all the time with M$ while Linux simply continues to work.

Regardless, can setup each GMX account but the default email account name must be used as the user name on the other two GMX accounts on the outgoing server in order to send email. Then the recipient sees the name for the default account rather than the name assigned to the other two accounts, and the Application-specific password for Thunderbird must be changed to that of the default. Then attempting to pull down email for the other two pop accounts comes to a halt, and email messages can only be viewed by going to the online account.

Two separate accounts for yahoo, two for gmail, and one for Charter work fine, each has its own name and outgoing server. Should be the same way for GMX but is not because Thunderbird requires one of the three GMX accounts is set to Default.

Appears by having a Default email account, users are not only restricted by the default account, but email that is sent is done so with he incorrect name, The purpose for three different emails is for email segregation and better management; personal correspondence, business related, and Internet stuff.

Instead of having a 'Default' email account, makes more sense to use a valid email to register Thunderbird after downloading and installing, and then using that email for Support, Boards, assistance, etc. The default email requirement causes too many frustrating unneeded issues that should not occur, along with wasted time, stress and grief. Computers were suppose to make our lives easier and allow us more time for the real world. Biggest lie told since the Bell Labs created the transistor.

Cannot send or receive email all of sudden in Thunderbird. When I the click the messages icon, nothing happens, and I get "Could not connect to server mail.twc.com; the connection was refused". When trying to send a m,message I get "Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) mail.twc.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again." No settings were changed and everything was fine when I put the computer to sleep. This happens on both a Win 7 and 11 machine Email is a Time Warner (now Spectrum) Road Runner account (twc.com). Spent an hour with Spectrum, and they say this is a third party (Thunderbird) issue. A friend has the same setup, and is having the same problems that started at the same time.

Appreciate any help....

recently, e-mails have been hanging. I have determined that it is, for the most part at least, USPS mail tracking e-mails that hang. Once I delete or move to archive, things download fine.

This is not the daily Informed Delivery e-mail.

This is like "your package (tracking number nnnnn) has arrived at the distribution center. Expected delivery mm/dd/yyyy.

I have restarted, repaired in box, etc.

Any help?

After a lot of research, I thought I had the filter issue conquered. I perhaps made them too complicated, using several "match any of the following" by using the plus sign and entering into the second window which appears. I used "match any of the following" For "from" I chose "from, subject, cc". After creating a zillion of them, I wanted to edit one or more and when I click "edit" I get: "This filter was probably created by a newer or incompatible version of Thunderbird. You cannot enable this filter because we don’t know how to apply it." Using 151.0 (64-bit) Thanks....

I have now the version 158.01 (64-bit) with Windows 11. My Gmail account only dowloads email like once a day. The server settings are: -Check for new messages at startup -Check for new messages every 10 minutes This started a few days ago, while I had the version 158.00. I have many accounts on Thunderbird, and re-installing all of them would be time consuming. Any suggestion?

I had heard that Thunderbird is a great ad-free alternative and I started using it some time back as an alternative to direct Yahoo or GMail use. I did not know that your default is to delete (from the server also!) mail older than 30 days!!!

I've had medical and financial records and other things that I've kept for years on my Yahoo account that are just gone due to your settings. Is there any way that I can recover messages from certain folders?

I am unable to move an email from my inbox to my folders.Thunderbird is unable to complete.Get [clientbug]append error message.AI informed me that yahoo did an upgrade and Thunderbird now has is issues with Yahoo and needs to do a upgrade.Is this true?

As a twelve or more years user of Thunderbird, I find it to be okay most of the time. I hate the spam folder that does not learn and I hate threads.

Today all of a sudden, I cannot save photos sent from my iPhone as jpg. I have always right clicked and a menu has appeared. Today, the right click just zooms in which I never want to do when I am trying to save.

I tried searchig online first before coming here. Apple is claiming that Thunderbird developers made a mistake and that is why the right click is not working. AI had me try a bunch of different techniques none of which worked.

When I do save after much effort, the "photo" in my Animals folder appears as the Thunderbird logo instead of the real item itself. The other weird thing is that my folders also do NOT show up where they should when I am trying to save. The menu doesn't give me all the folders as it always has. Instead it just say All Files which is not adequate.

I tried to connect using my proton mail, with the correct credentials and mail, using IMAP (auto), but I received the same message: "No se puede iniciar sesion en el servidor. La configuración, el nombre de usuario o la contraseña probablemente son erróneos".

How can I do to solve this?

Descripción: ProtonMail Nombre del servidor: 127.0.0.1 Puerto: 1025 Nombre de usuario: pixxxxxxx@proton.me Método de identificación: Contraseña normal Seguridad de la conexión: STARTTLS

To ask this question, I had to sign in. But the password to sign in, which permits me to reach this page, where I can ask this question, does not give me access to my email. I have tried using my apple account password and my computer password to no avail. How do I fix this?

I have/had two different problems with the same results. In the first case I get the login window. I enter the password hit return and that window goes away and some times you can scroll to different opened emails before it says "Not Responding". The only action that works is to exit the app. Usually after a few days or weeks it will start working and does so for a few days or weeks. Lately the login window does not appear when the app opens and it displays the "Not Responding" message. It shows that it is "Loading Message". I have tried all of the options from the troubleshooting window and reinstalled Thunderbird with no change in response> Where do I go from here?

Hello New to TB, it's working well. My question is that I can't find a setting that causes emails to be downloaded immediately from the server as soon as they are received. Is there one?

The only available settings I can find are

Check for new messages at startup Check for new messages every (minimum 1 minute) Allow immediate server notifications when new messages arrive

If I have all of these checked then I should get an immediate sound and/or visual notification when a new message arrives on the server and I can see its header, so what is the significance of the "check for new messages every (set to 1 minute)" setting? Does that mean it will download all messages, including bodies, received in the last minute without any user input?

It seems I will shortly not be able to use TBird

I received this message

'You have been identified as a user of the mail app, Thunderbird, which has been set up to access your University of Glasgow email account.

This app uses a protocol called Exchange Web Services, which Microsoft is planning to retire. Microsoft has advised that this protocol will be disabled in tenants from this month (October) through till April 2027, when it will be permanently shut down. We do not know when the protocol will be disabled in our tenant.

Once it has been disabled, your mail app will no longer work and you will need to switch to a new application such as Outlook which will continue to work.

Regards, M365 Admin Team.'

Can this be fixed?

Hi there, I’ve spent many hours trying to find an answer. Perhaps it’s right under my nose, but I just can’t seem to find it. Please help!

I’ve created extra folders in Thunderbird to keep my messages organized. Question: How can I locate a specific folder?

Example: I create a folder named "a555". I CANNOT FIND THE FOLDER "a555".

(why did I choose "a555"? It’s a unique combination of letters and numbers, which ensures there are no unintended search results.)

Searching for a message does reveal the name of the folder it’s contained in, but that’s not what I’m looking for. I want to be able to search for the folder itself directly.

I have tried searching using: Global Search (top right) – Ctrl + K; Specific Search – Ctrl + Shift + F; This Thunderbird forum; A general search on the internet.

Any answer would be greatly appreciated. Arthur Cerew.
