Diễn đàn hỗ trợ Thunderbird

I am not able to send or receive emails on my computer using my Thunderbird account. I've tried using the instructions on passwords, but nothing seems to work. Irene

my email, redacted@gilanet, stopped coming through at 12 noon. I called the server, gilanet.com and he had me delete the redacted@gilanet.com account and then readd it. It won't let me add the account. It says it can't find the server. They put in a trouble ticket but don't know when they will get back to me.. Any help would be appreciated

After clicking on the message pop-up on the Thunderbird email client, the email appears blank,Open other windows to overwrite, then close other windows to resolve the issue. How can I view emails normally after clicking on the message pop-up

I am unable to connect Thunderbird to my “Personal” Outlook.com mail account. I installed Thunderbird on a new laptop with Win11-home. I connected to yahoo and icloud without issue. In the past I used an app-specific password to connect Thunderbird to Outlook. But Microsoft no longer allows me to make app-specific passwords on a personal account. I have two factor authentication on the MS account. I have tried turning off virus and firewall protection, without success.

When I create a new email account in Thunderbird I get the following error. “Authentication failed. Please check the username and password - Exchange auth error”

If I put my personal name in the Your Logon field, rather than my email address, I get a Microsoft screen pop that shows “oauth2” in the URL. But if I click the personal account they present it quickly fails.

Is there a workaround, to fix this, since I can’t get a app-specific password and have two-factor authentication on my Microsoft account?

Thank You for any help you can provide. I have spent a day researching this without success.

"Login to server pop.verizon.net with username druckerm failed." I can't get my email anymore. I've tried entering in a new password, but that also fails. Thanks for your help, Marilyn

For no apparent reason, my Thunderbird email account which I have had for years without any issues has stopped downloading emails. I can still send emails, but the download bar just keeps going eventually giving me the message below.

My internet provider is Verizon and the email I am linked to is AOL mail.

Any help would be apprecaited.

Two nights ago I uninstalled ExpressVPN from my system at the instruction of one of their "support" people. My computer immediately lost the ability to access half of the websites I tried to visit and Thunderbird wouldn't send or receive email. I rebooted and that fixed every issue, but since then, Thunderbird no longer checks for new messages for any of my accounts. If I manually instruct it to check, it downloads the messages with no problem. I don't use any add-ons, and I'm using the latest version on a Windows 11 PC. I have already tried deleting global-messages-db.sqlite, repairing each mail folder from within Thunderbird, clearing the cache, and running an install of the latest version. I have also tried changing the setting for each mail folder to alter the interval for message checks by a minute just to see if that would jog it, but no luck. I've looked at various other help threads for this and am out of ideas. Thanks in advance for any help.

Thunderbird stopped getting incoming email. I can log into my email via a browser to my email provider and get current emails that way, but not through Thunderbird.

I AM able to send emails, and they are received at the other account. However, they don't show up in my Thunderbird "sent" folder.

My provider tech support was unable to help me correct this, but all settings appear normal.

I restarted Tbird, and rebooted the computer. Nothing changed. I'm running windows 11.

Thunderbird can not receive emails but it can send them. Password is correct.

  ( Login to server pop.verizon.net with username ... Failed
    Connection timed out)

Account Settings -> Server Settings:

   The certificate for pop.verizon.net:995 appears to be valid.
   When viewing the certificate it is out of date.
   No option to add an exception here or under Manage Certificates

On another user on the computer Thunderbird is working.

Thanks

Is there a way to set up TB to download messages from the server together with remote content without ever opening them? At the moment remote content (pictures, etc) only downloads when I view a message. Naturally, remote content is allowed for everything in the setttings. What I'd like is to pre-download everything, so that, say, I could download the latest messages, board a flight, and work in transit without needing access to the Internet. Thank you for any suggestions!

I am having problems being able to send emails if Surfshark is activated. Been working with Surfshark for the last week or so. So far no luck. FYI: I do run Bidefender, AVG TuneUp and CCleaner. I have added an exception to Bitdefender. No changes to not being able to receive or send emails. None of my settings have changed in Surfshark or Thunderbird. Using Open VPN protocol and am getting a message all the time about Thunderbird trying to connect with connecting to imap.comcast.net and it just stalls there. If it does get sent, it does not get saved to the sent folder.

Also, at times when I close Thunderbird I have to go into task manager and delete before I can open it up again.  Any ideas?  Thanks

Have been using CompuServe.com for years suddenly logon password fails. is AOL (CompuServe.com) down right now works in a browser not in Thunderbird.

Please advise.

I have just started getting this error message when sending email from my @live.ca account. I do not get this message when sending from a @gmail or @company.ca address.

Quote: "Sending of the message failed. An error occurred while sending mail. The mail server responded: Non-Compliant sender address. Code : -1. Please check the message and try again."

I can send and receive email using this address from my Android phone or from my Windows eMail client, so why is Thunderbird causing this? I have looked through all the setting and cannot find anything different from the settings for the @gmail accounts.

Thanks. Dave

Using Thunderbird 140.5.0esr (64-bit) email program, can not send emails. Get message: Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: Connection from 69.119.30.125 refused. Have multiple email accounts - all get same response. Have tried several computers -all get same response. Can receive emails with no problem. I have spent several hours with my service provider [Optimum] checking/changing Server settings to no avail. They claim all my settings are correct and say the problem is not on their end. On the Optimum website email – I can send emails with no problem. I installed Outlook and set it up to the same servers and can send emails from there so it would seem Thunderbird is the problem.

Running WIN10 on 1 machine, WIN11 on another. Both same issue

I have been using Thunderbird to access my comcast emails. I never had a problem with it. However, this afternoon, just out of the blue Thunderbird cannot download my emails, the following message popped up: "Login to server mail.comcast.net with username xxxxxxx failed." Then Thunderbird asks for a new password. When I enter the still correct password, it displays the same error message. I did not change anything in the settings before this error message popped up. I tried ChatGPT to get some answers, but whatever I changed it had no effect. I am attaching a screenshot of the server settings (I have of course removed my username). I would be grateful for any advice as to how to fix the issue. Thanking you.

When I start Mozilla it checks for new mail. It always says no new mail. When I click on get messages if there are any new ones I get them downloaded. Why doesn't the first check find new mail as it used to? Thanks
