After being migrated from f9 to Greenby my service was suspended by Greenby for several weeks. During this period I was getting requests from Thunderbird for pass word. The Greenby is now reinstated but I am still getting password requests from Thunderbird and cannot connect with my original email address.

I have 3 different hotmail accounts. And tried to set them up in a newly installed thunderbird app on windows (10,sorry not up to date). In the beginning I had 2 out of 3 working, but the last one is my business account and it didn't connect. I tried many different ways to get it working, and now only the 1st one is still connecting correctly. The second one also doesn't connect anymore and is giving me the: "The connection was refused when attempting to contact localhost." or Authentication error: Unable to log in at server. Probably wrong configuration, username or password.

I know for sure password and username are correct. I have added thunderbird to exceptions in firewall. I also tried turning the firewall off. no changes. I have no idea where it got so messy but can someone guide me in this? Most of it I do not understand so it is obvious I made mistakes.

After updating Thunderbird to version 150.0.2, I can no longer connect to my lolipop.jp mail servers.

Symptoms:

• Both IMAP and SMTP stopped working at the same time
• Webmail works normally
• Multiple mail accounts are affected
• Thunderbird times out when connecting to the servers
• The issue started immediately after updating to Thunderbird 150.0.2

Settings tested:

• IMAP: imap.lolipop.jp / Port 993 / SSL-TLS / Normal password
• SMTP: smtp.lolipop.jp / Port 465 SSL-TLS and Port 587 STARTTLS
• Tried Thunderbird Safe Mode
• Tried reinstalling Thunderbird
• Tried disabling Norton security/firewall temporarily
• Same issue persists

Could this be a known issue with Thunderbird 150.0.2? If so, is there any workaround or planned fix?

Thank you.

I have deleted an email account, then I made sure that the saved password and any traces of the account are gone, but every time I launch the program a window pops up with this message:

Authentication Required - Mozilla Thunderbird https://ha1012.raiolanetworks.es is requesting your username and password. (and the account I had before deleting it)

How can I stop that window from appearing again?

Thanks!

I have been trying to add my accounts to Thunderbird and had good success with gmail but wasn't able for Microsoft accounts. As I said in another thread (can't find the message anymore), I have 2 microsoft email account (one live.ca and one hotmail.com) and they both don't work. I was able to add them in Outlook desktop app and EM Client (a non open source software i'd rather not use) through IMAP with success. IMAP is activated in both accounts and as per Microsoft documentation the server is supposed to be outlook.office365.com on port 993. eM Client magically discover IMAP settings to imap-mail.outlook.com instead. Thunderbird opens an OAuth page and then it redirects from microsoftonline.com to localhost and fail with "Unable to connect".

2FA not activated in one account, if that matters. I have nothing running on port 80 if that matters.

This only recently started happening. This has been tested on 3 different computers. Windows 10 Pro on all three.

With VPN on: Bluemail works fine.

Thunderbird can connect and download messages, but when I try to send a message, it gives an error.

With VPN off:

Bluemail and Thunderbird both work fine.

I use Thunderbirad for years, including small donation when I start to use it. Since a few days I can not open WebMail from cPanel of Namecheap,

Nothing is changed in both servers and ports. In Account Settings Outgoing Server has an option to TEST connection for server. Result failed.

An Attachment is an immage of TEST and RESULT FILED.

In this age, with broken spine and almost immovanle, it makes me very frustrated. Coud you plase reaolve this issue and make Thunderbird to work properly and peace in my mind,

Hello,

I recently upgraded to a new PC from Windows 10 to Windows 11. For some reason I can not open links in any emails, even if right clicking them. I have gone through all steps here: http://kb.mozillazine.org/Standard_diagnostic_-_Thunderbird but nothing has changed. I have disabled Win Defender completely and still no change.

Any idea what I am missing? I am at a loss at this point.

Thanks for any advice or direction.

Hi, I use my Thunderbird installation as a feed reader for RSS. Unfortunately, there are two feeds which aren't updated any more. I can't find an error. The feed is OK, I checked the XML file - the new entries are in the feed. The same feed works with a different feed reader. I already deleted the feed and added it again to Thunderbird. That didn't help. I don't know how to find the error. One of the not working RSS feeds is this one: https://mastodon.social/@islieb.rss

When I execute "right click -> Get Messages" on the feed, nothing happens. No error message... What can I do to find the error?

I'm running Fedora Linux 43, Workstation Edition; Thunderbird 140.10.2esr from Flathub. Everything's up to date.

Thanks, Simon

Starting yesterday for no apparent reason TB has been unable to connect to my email accounts. (IMAP or POP). These include Roadrunner, Gmail and Outlook.

Any Ideas? James

Everything has been fine for several years but this morning I now get error: TB could not connect to server mail.twc.com, the connection was refused. Spectrum says everything is good on their end. What do I have to do to "fix" Thunderbird? I can't send or receive any emails from 5 accounts with Spectrum and the emails are there when I log in at WebmailSpectrum.net..

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. Win 11 version 150.02 Win 7 115.18.0 (latest available for win 7)

Appreciate any help....

I'm getting "Thunderbird can't connect to the server" message, so I can't download messages. However, a message or two will finally download 1-2 hours later.

Same problem on 2 laptops, both running Windows 11. But I know my emails are coming in as I can view them via Spectrum webmail. So the problem isn't the Spectrum servers.

I've logged out and back into Thunderbird, and have re-booted my laptops. No luck. What to do?

Also, is there a place to report problems directly to Thunderbird?

Thanks for any help.

All of a sudden today I'm getting the message "could not connect to server mail.twc.com; the connection was refused." So, I'm unable to send/receive email. I called Spectrum and they said go to Spectrum.net. Yes, I was able to get my email that way, but that eliminates the ease of using Thunderbird. I've read all the messages about this issue, including changing various settings, but none have helped. Spectrum says nothing has changed on their end and it must be a Thunderbird issue. My current settings are: Incoming: Server Type: POP Mail Server Server Name: mail.twc.com Port: 110 User Name: [my email address] Connection security: None Authentication method: Password, transmitted insecurely

Any other suggestions?

Hello. Impossible to connect to an existing Google account. Neither to the "full" account, nor to the Contact list nor to a Calendar of an existing account. Neither to a "private" account, not to a "workspace".

When trying to connect to a Contact list, after the Oauth window and the authorisation to share data from Google accounts, the app answer "Connexion impossible" (I am a French user).

When trying to connect to Calendars, Google's window asking authorisation to share data comes back after clicking "authorise".

Why am I getting this message when I try and send an email from my Mozilla email client: Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.gmail.com timed out. Try again.
