Thunderbird Community Forum

I need help to log into Thunderbird. I get the same message over and over again (login to server imap.videotron.ca with username...............failed. I've tried several tried and true passwords from before and none fit.

Thunderbird version 147.0.1 does not send email. I use Windows 11 Pro with all updates current. I can receive but cannot send (reply to) emails. I have not changed any email settings. What is the solution?

Thunderbird 140.7.0esr allows me to e-mail my OpenPGP public key to myself, but it doesn't seem to have any way for me to get access to my private key. I was wondering how to export keys? Thanks!

We are a fatcow.com user, I know the company has been bought out by another company, but outlook stopped working. They no longer support outlook 2010, so I switched to Thunderbird. I get all my new messages fine, but it errors trying to send new messages. Error message has been uploaded.

thx

I have smtp.gmail.com set up as my outgoing server (port 465, username = my gmail address, Authentication = OAuth2, connection security = SSL/TLS, also tried STARTTLS with port 587). There doesn't appear to be any way to set the password in the "Outgoing Server (SMTP) Settings", even when I click "Edit". Nor can I add a password to the "Edit/Privacy&Security/Saved Passwords" dialog box (which allows you to see existing passwords or remove them, but not add any).

When I try to send an email, the "Sending Message" dialog box pops up, and after a few seconds a second box pops labeled "Login to account 'smtp.gmai.com' failed". This box has three buttons: "Enter New Password", Cancel and Retry. Clicking on the "Enter New Password" button does not offer me the chance to enter a new password--instead, it immediately takes me back to the "Sending Message" box, which then immediately takes me back to the "Login...failed" box. There is never an opportunity to enter the password!

TBird 140.7.0esr, Thunderbird for Linux Mint. Mint version 22.3.

Sending works ok if I choose a different SMTP server.

TBird Version: 140.7.1esr

Since yesterday I can no longer click through with hyperlinks inside an email message.

I don't understand this.

I have already tried all the troubleshooting items to no avail.

To my mind, a change was made to TBird's functionality and this is stopping the click-through to the default browser and the opening of the page linked.

The Thunderbird password I've used for YEARS (and is stored in "Saved Passwords") no longer works. I have two laptops with the same password, and they both ceased (on the same day) allowing downloads (or sending) of emails. This occurs on both my laptops -- one has TB version 115.10.1 w/ Windows 10, and the other has 140.5.0esr w/ Windows 11. It also occurs on my iPhone when trying to access the mail server.

Could the problem be the mail server itself?

the problem is that when I receive an email it goes straight to delete folder there is no where I can set the filters to filter of my choosing, I have lost losing all in coming mails I am talking with telstra as one page said it is an IMAP problem in that it just removes emails for no reason but in your problems page it says I can change the filter settings but in the settings there is no place to change filter rules

I am getting very frustrated  after 6 hours and not getting anywhere  I have uninstall Thunderbird and reinstalled  but nothing changed 
running win 11os  on desktop 

what do you suggest

I tried to use both robertipp@gmail.com and robertippolito6@gmail.com for my system (along with others until I retired).

I've tried to work with Mozilla, but I cannot get an early system and another laptop (two I've been working). I've tried to work with Mozilla process, but I just cannot to get it to work. I tried to work your process, but I seem your process as asking me to read data that I seem coming close, but working with us. The last information was data, but a little error (?, mine or yours) popped up. My data that I wrote up, then I changed my data for robertippolito6@gmail.com very carefully, but the error this time had to be your error or an blend of data because many of your team and mine are just mine.

I give up. I cancel my contract. I've had to take my laptop for many trips to help with my older brother and who suddenly died. I was spanning around for quite some time to work.

January 31, 2026 is effective canceled. Please refund to me as said.

Is it possible to change the account name in "Account Settings" without any issues and will this make the mail folders accounts panel on left of the screen show the newly entered name for folders and sub-folders under sent, archive, etc?

The reason I ask is because I think it is ok to initially name the account as whatever I want, as I think the account name is for my own use only, but I'm not sure if changing an existing account name may cause issues or if TB uses the account name for anything.

I tried unticking enable and it did NOT work. Help! I want the stupid filter gone. I have struggled for two years with the junk filter which does not work right. I have done shift J. The filter does NOT learn. A week aog, I saw that I could uncheck enable and that was supposed to stop the filter. That also did NOT work.

Today, an email I forwarded to myself from another platform went in junk. I never wanted any junk filter. It has been nothing but trouble and now I can't even disable it.

Jeg har modtaget en mail som jeg vil videresende til en anden person. De modtagene mail ser sådan ud se billede Skærmbillede 2026-01-28 152737.jpg Når jeg sende denne besked videre kommer der først en lang teknisk liste, se skærmbillede Skærmbillede 2026-01-28 153123.jpg

Hvordan undgår jeg at få al den unødvendig information ?

I have 4 IMAP accounts and 1 local account. I would expect them to be shown as account 1,2,3,4,5, but Thunderbird's troubleshooting info shows them as 1,2,5,7,8. Please see attached picture.

Any idea why? Has something gone wrong? They all seem to be working ok.
