My emails will not download in Thunderbird. It shows a server connection but the server is fine. I can even hear the tone like emails are downloading but I cannot find them.

Issue is with spectrum server mail.twc.com. Error message sending and rec e mail. "Outgoing server (SMTP) mail.twc.com failed. The server may be unavailable or is refusing SMTP connections." "Server timed out" Server settings are correct. need help!!

I use Proton email, but considering the latest revelations from the leadership at Proton and their treatment of employees I am looking for an alternative. Does the Thunderbird team rely on AI for coding? If they do rely on AI is it checked by a person before being used? It seems Proton is satisfied with letting AI code with minimal or no checking by a human.

Hello,

I'm very fond of Thunderbird (using it only for agenda, but a lot) and I think that a new practical function would be to be able to paste plain text (= without formatting) with the right click of the mouse into an agenda cell.

As I add a lot of events and text into the agenda cells directly from websites or documents, I'm always getting the original formatting that I don't need and can look quite bizarre.

Plain text could harmonize everything. I know I could select the text and reformat it in Thunderbird but it's adding unnecessary steps.

Thanks in advance for the consideration of my proposal, thank you developers, and have a good day !

Windows 10 Thunderbird Version 159.0 (64-bit)

Today, Nov. 5, opened Thunderbird & got the Error message: Unable to write the email to the Mailbox. I have no idea why this happened. Turned off the antivirus for email, but that did no good.

Thunderbird worked fine yesterday

Suddenly was unable to send mail on either of my laptops. I have uninstall and reinstalled Thunderbird and windows. All of the SMTP setting are correct. I have tried different combinations of settings but no luck. I have tried every fix on the internet. I am using Spectrum (TWC) for internet. I talked to them but got nowhere. I've used Thunderbird for years and have donated to keep it going. I really like it and don't want to change. Hope you have a way to get me going again. Thanks, Mike

I currently get my email from Spectrum.net. They have made some changes that necessitates me making server changes in Thunderbird. I can't seem to find a way to do that. Everything seems to point me to a new account. If I set up a new account will I lose all of my eisting emails on my desktop?

I have tried various suggestions, but they all seem to send me to menu options that just do not exist.This is a really old problem and I can't understand why it has never been properly addressed.

Automatic spacing is pretty much universally not standard (It does not occur here.)

So how do I stop auto/double spacing when composing a message, please?

It seems that saving mails af text.files has been changed within the last month. Becouce the filename in the overwiev has been shortent and supplied with " ... - " - wher can I find a decription of that ?

I have a Win10 PC and a Win11 Notebook. Yesterday I could open my email accounts on both: PC and Notebook. But today suddenly I get the notification, the Thunderbird versions are different and I can not open my email account. Thunderbird versions on PC: 153.6.0esr and Notebook: 159. Why did Thunderbird on the PC not actualise automatically to a newer version, even under Help/About is written "Thunderbird is actualised"?? see attached screenshot.

I am using Thunderbird 158.0 (64-bit) on Windows 11 and cannot connect a newly created Outlook.com email account.

The account works correctly through Outlook.com webmail, but Thunderbird consistently reports:

"Authentication error — Unable to log in at server. Probably wrong configuration, username or password."

I have spent considerable time troubleshooting this problem and have already completed the following checks:

Confirmed that IMAP access is enabled in Outlook.com.

Verified incoming IMAP settings:

Server: outlook.office365.com

Port: 993

Security: SSL/TLS

Authentication: OAuth2

Verified outgoing SMTP settings:

Server: smtp-mail.outlook.com

Port: 587

Security: STARTTLS

Authentication: OAuth2

Confirmed both usernames are my full new Outlook.com email address.

Confirmed that Microsoft lists "Mozilla Thunderbird" as an authorised application, with permission to read, write and send email.

Tested network connectivity using Windows PowerShell. Test-NetConnection outlook.office365.com -Port 993 returned TcpTestSucceeded : True.

Created a completely new Thunderbird profile containing only this Outlook.com account. The same authentication error occurred.

Tested Thunderbird Troubleshoot Mode without success.

Confirmed cookies are enabled and Windows is not using a manually configured proxy.

Removed saved OAuth2 credentials and retried authentication, without success.

Tested both external-browser and internal-browser OAuth2 authentication using mailnews.oauth.useExternalBrowser. Neither worked, and I restored the original value of true.

During an earlier attempt, the Microsoft authentication process displayed the error 127.0.0.1 refused to connect.

Microsoft's authorised applications page confirms Thunderbird has the necessary permissions, but Thunderbird still cannot authenticate. I have not successfully been prompted to enter my new Outlook.com account password through Thunderbird.

My existing Hotmail account works in Thunderbird.

Could this be a known Thunderbird 158 OAuth2 problem affecting newly created Outlook.com accounts?

As the usual configuration, password, permissions and network checks have already been completed, I would appreciate advice on identifying the underlying authentication failure rather than repeating those steps.

Thank you for your assistance.

I have the latest version of thunderbird. This has just started in the past few weeks. I have 3 separate emails that thunderbird handles for me. The main one seems to work fine but slow. The other 2 it keeps asking me to input the password for them. I don't know why because it never asked before. I input the password and it does not accept it for either accounts. why is this happening and how can I fix it. These are roadunner accounts. I know they are "legacy" accounts. We are switching to another email service but need to access the current roadrunner ones for a period of time to make sue we get everything switched over.

Any help will be appreciated.

Thanks Bob

my email was previously provided by internode, which stopped. I transferred to the messenger co keeping my email address [redacted]@internode.on.net. However when I activate thunderbird I get a drop down box saying

mail.internode.on.net with username [redacted] failed

I used the option of "cancel" and things worked ok

Each time I open Thunderbird I get the same drop down etc

It is anoying

Does this make sense?

Thanks PIL

In thunderbird I'm getting the "Help Keep Thunderbird Alive" page, when I click the link it opens the same page (https://updates.thunderbird.net/en-US/thunderbird/140.0/nov25c/donate/?form=nov25&utm_content=cta_c&utm_source=in_app&utm_medium=desktop&utm_campaign=nov25_appeal) in the browser. The click to donate button there just opens the same page again and there's no option to donate. The page has a notification that "an extension might be blocking our donation platform" but disabling ublock on the page does not change anything.

Do you have a working donation page anywhere?

The functionality of the addressbook is very frustrating to me.

I have about 1000 contacts in my addressbook, which I'd love to sort into groups. And when writing an email to a certain group, I would like to display the list of that group in the sidebar of the Email. However, this is only possible when I make a new addressbook for each group, because only addressbooks are displayed as a list with all the contacts contained.

Now most of my contacts are in several different groups/addressbooks (for example, "Steve" is in my "hiking" group and also in my "work" and "neighborhood" group). However, one contact can only be in one addressbook. Meaning if I want to add Steve to the different groups/addressbooks, I have to copy his contacts three times to be able to put him in the three different groups/addressbooks. Doing this for all the contacts I have, it would get cluttered very much, very soon. Which I find super frustrating because it can get very confusing and it just seems so unneccessary. The other frustrating thing about this is, you can't just copy a contact, but you have to create a contact manually each time or via the "save email" button in received emails. But the latter can also be confusing because the format of the saved contact can vary; Steve can either be "Steve Smith" one time, but also "NameIThoughtWasCoolWhenIwas12@narf.org" another time.

What I'd love to have is ONE profile for each contact where I can put in all the information I have/need/want and that profile can be part of several different groups. If a contact has more than one email in their profile (i.e. privat, work), I'd ideally be able to attach one email to one group and another email to a different group. And obviously, the group can also be displayed as a list in the sidebar while writing an email (just like addressbooks are now).

I don't know how it can be implemented (keywords, tags?), but it would be great if it was possible.

I also don't know if it is possible already and I'm just to slow to get it. So if anyone knows a) how to add a contact to several addressbooks without having to copy the contact each time or b) how to display a mailing list as a list in the sidebar, I'm all ears.
