When I try to send an email, I get the following response. Sending of the message failed. An error occurred while sending mail. The mail server responded: invalid user ID or password. Please verify that your email address is correct in your account settings and try again. Have looked in account settings and cannot see a password anywhere. Email address is correct Help please Carol

I'm using gmail/outlook/hotmail email addresses on a new win11 laptop with Surfshark VPN and getting email up & running is the last major set up issue. I am having issues with both send & receive emails across all addresses. I get some functionality if I pause the VPN (not ideal!) but not total. I have tried the Surfshark bypass function for Thunderbird but without success.

I have had no issues with this setup for many years on win10.

Using Outlook (one email address) on the web with the Surfshark Chrome extension I can both send & receive.

1. what should the IMAP & SMTP server settings be for gmail/outlook/hotmail? 2. are there any known issues with Thunderbird/Surfshark? 3. are you aware of any issues with gmail/outlook/hotmail blocking Surfsahrk?

Can't get email from Comcast server any more & a lot of existing emails disappeared. Was on the phone with them & reset ports & checked other things but it didn't work. I can read them at Comcast's site & also send & get them there. Also can you help me forward my email to another email program?

I've been a Thunderbird user for years without problem. However, since May 22, three specific messages continually reappear after deleting them from my Inbox.

I keep my Inbox empty and it stays that way, except for these 3 messages. Removing them from the Trash folder has not solved the problem.

My email provider is netaddress.com via POP3 account. I signed on to look at my inbox on their site via a browser, and the messages aren't there.

I have tried repairing and compacting the inbox, but the messages continue t reappear.

Do you have any other suggestions?

TIA.

Using Thunderbird with Spectrum email (an old roadrunner address). Changed the outgoing server to the following: Server Name: mobile.charter.net Port: 587 Username: Reefside@cfl.rr.com Authentication: Normal Password Connection Security: SSL/TLS Testing connection fails. I have tried different combinations and once in a while I get that the connection is successful, but email sending hangs and never completes.

I've been seeing a doubling of *some* incoming messages, where a duplicate message comes very soon after the first one. For example, two incoming messages were received at:

Sun, 07 Jun 2026 14:03:10 +0000

Sun, 07 Jun 2026 14:04:31 +0000

So the second message came in about 1 minute and 21 seconds after the first, and not because of anything I did (as far as I know). But then that was it, no third message came in.

This isn't really a bug, as nothing is harmed, just a repeated message. Any thoughts would be appreciated.

Hello. Some email addresses are no longer being delivered and are not appearing in my spam folder.

This started about three weeks ago with just one address. Now, I know of at least two.

Emails from these addresses that I used to receive and delete have also disappeared from my spam folder.

Does anyone have a solution?

Thunderbird version number: 148.0.1 Mail provider: Yahoo Client OS: Windows 10

The issue and steps I tried to resolve: On 1 Jan 2026 I switched from Outlook client on my Windows 10 PC to Thunderbird 146.0.1. I did not import any user data from Outlook but started with a clean install of TB for the new year. I use yahoo.com with POP3 as my email provider. Server Settings: Server Name "pop.mail.yahoo.com", port 995, SSL/TLS, OAuth2 Outgoing Server: Server Name "smtp.mail.yahoo.com", port 465, SSL/TLS, OAuth2

it all worked fine and I was very happy with the setup. Then from early to mid-February I was unable to use my computer. When I finally accessed Thunderbird again, it connected to Yahoo and showed that approximately 800 email messages would be downloaded and started downloading them. After downloading about 100 messages, Thunderbird timed out and I haven't been able to get it to work since.

I have read and followed or tried to follow these articles plus others that I may have forgotten about (not listed in any particular order) - OAuth2 Authentication for Yahoo, AOL and ATT | Thunderbird Help - including all the steps in Please check the following before asking for support - POP access settings and instructions for Yahoo Mail | Yahoo Help - Automatic Account Configuration | Thunderbird Help - Manual Account Configuration | Thunderbird Help - Thunderbird and Yahoo | Thunderbird Help - Send and receive messages in Thunderbird | Thunderbird Help - Can no longer get emails | Thunderbird Support Forum | Mozilla Support - Emails suddenly stopped downloading to Thunderbird 140.2.1esr | Thunderbird Support Forum - Get Messages | Thunderbird Support Forum | Mozilla Support - Cannot receive messages | Thunderbird Help - Problem with Thunderbird working with Yahoo Mail acccounts. | Thunderbird Support Forum

I have removed all messages from the Yahoo inbox and tried to find one or more messages that may be affecting the download. I don't know the best way to determine that.

I use Windows Defender for my antivirus. I don't see anything in Defender that blocks or scans email messages which would prevent downloads, although I could be wrong about that. if this might be the issue, please provide some guidance about how to check Defender.

I have uninstalled and re-installed Thunderbird. In the process I downloaded the setup file for Thunderbird Setup 148.0 and installed that version. It later auto-updated to 148.0.1. Before installation, I removed all external connections from my Yahoo account and completely removed Thunderbird from my PC, including the profile and profile.ini. When I reinstall and switch the account to POP3, Thunderbird captures the App password from Yahoo and connects just fine. But it still times out while attempting the first download of a message. The first several times it timed out, an error message was displayed but now it doesn't show anything. Except no messages are downloaded.

At this point, I don't know what else to try. Since I don't have much experience with Thunderbird, I don't know how to troubleshoot the process (logs to look at, etc.). I don't want to go back to Outlook but I need the email client to work and download messages. Any help would be much appreciated.

Thunderbird will connect to my yahoo server, but will not "bring in" the mail. The msg bar will say for example "loading 1 of 76. The doesn't until server has timed out.

I have an Orange.re email address, and whilst I can receive emails, I am unable to send emails. Any ideas why? I have verified the smtp server and settings.

Hello

i am struggling with TB as it always uses the default email of a server account.

Instead, i would like to use different accounts based on the recipients

I could not find an extension with this behavior.

For example, I would like all email exchanged (sent & received) to a domain ( @thatcompany.com ) to use a given account alias (myalias.email@proton.me)

Thanks for all assistance

When we first started using a third party application to track our customers information & jobs; we received emails showing the customers name on the correspondent/from column. Now all of the emails show the third party applications name and I do not know which customers are trying to contact us.

I have used Apple Mail, GMail and Outlook; i am hoping that Thunderbird will achieve (relative) zero inbox.

My objective is to create an inbox that observes established rules/filters and directs my emails into the appropriate folders. I was hoping that Thunderbird would achieve this objectives but I have so far been unsuccessful.

I would be happy to screenshare with an appropriate technician in order to resolve this issue as its becoming increasingly frustrating.
