Thunderbird Support Forum

I was notified by google that someone had my password and tried to log into my gmail account. I changed my password. Thunderbird requested the new password and I was unable to download messages. Then I tried to send a message and again Thunderbird requested my password. It did not accept the password. Now when I try to receive messages my password is not accepted and I get the error message Login to server imap.gmail.com failed. The choices are Retry, Enter New Password and Cancel. I enter the new password and get the same error. I went to Google help and I ensured IMAP is enabled. I clicked the link about Captcha. I've tried everything. I have the latest version of Thunderbird.

I use v102.0b5 (64-bit) on Mac OS 10.14.6 with a main password to protected my mail account passwords.

When I start Thunderbird, I have to enter my main password. Problem: The little window pops up several times even while I am already typing my main password. So I have to wait a bit until Thunderbird "calms down" and re-enter the password. But even after pressing enter, it may pop up again, but usually Thunderbaird has indeed received my password and the access to my mail accounts work fine.

This should be really fixed as soon as possible because it is very annoying.

Thunderbird is on my laptop. If somebody defeats my lock screen (or if I have a negligent moment), I don't want just anybody who accesses my laptop to gain access to my email. It is a security concern (retired CISSP here). Thus, I want to disable password retention. What setting will accomplish that without manually going in at every logout to remove stored passwords? I plan to do some international travel, and the laptop will accompany me.

I need a security certificate for spectrum.net's smtp and Imap servers. I installed thunderbird on a new laptop and I get an error on startup and unable to send emails

I keep getting the error "Sending of the message failed. An error occurred while sending mail. The mail server responded: 25KGq41h048594 This message has been blocked for containing SPAM-like characteristics.. Please check the message and try again." when I am trying to send regular emails.

How can I fix this!?

I get my Internet service through Xfinity but the account is in my wife's name & email. How does this affect the email/password I use when I set up a account? I have tried every combination I can think of and cannot get logged into TB! Very frustrating. Wouldn't it be easier to set up a TB User and PW and forget about the email provider? Seems to cause a lot of problems. Thanks!

I just received a malware spam that had an ISO malware attachment (filename something.pdf.iso). The email was not flagged as spam nor junk by Thunderbird.

Shouldn't Thunderbird be smart enough to flag any email with an ISO attachment as suspicious?

Hello, I setup my own mailserver. It has a valid lets encrypt wildcard-certificate for *.tld.com. The mailserver usees imap.tld.com for imap and smtp.tld.com for smtp. So the certificate should be ok. When i add an account to thunderbird i get the ssl-certificate exception for tld.com. But the tld.com should not be used, only imap / smtp. Why is thunderbird trying to validate a certificate for tld.com?

I followed the instructions for enabling oath2.0 for gmail, but I still can't enter my password. I verified my password by logging out of gmail and back in though the web browser.

I have the latest version of Thunderbird but am not able to get gmail to work after its latest security changes. I can receive mail but not send. I have done everything suggested on the Mozilla support page. Any suggestions? Thanks very much.

I have 3 thunderbird accounts ..2 of them connect fine to online gmail,,,,however the 3rd is getting invalid password messages.... I have reset the password in gmail and likewise in Thunderbird...but it is not connecting any ideas?

Trying to move from normal authentication for Office 365 POP account to OAUTH2, and the window that opens to authenticate is rendered with a bunch of bugs. Any idea if this is Thunderbird or Office 365's problem? Or how to resolve?

Thunderbird 102 has the ability to export your content, accounts, etc. But, it's an all-or-nothing solution -- there are use cases where one might just want to export your account info, say for use on another system you're building, etc.

Am I missing something? Is there a way to just select what content I want to export...

Thanks.

I run third party software called Planeplotter and Planebase. Every night ar midnight it creates a log - really a text file. For years I have been sending this log to three interested parties. Since - about the 1st June, my log is not automatically sending. It is setup to send at 0001 every night to an address in google groups and also io.groups. Since 1st June I am getting an error message when I try to send via my Thunderbird software - gmail account. The error message is 0x80040217 unable to send to the SMTP server.

Since 1 June, I have migrated to a different PC (win 10) as my Win 7 PC eventually fell over. I have new versions of all my software, which, as far as I am concerned comes from a known and reputable source and I have been running it continuously for over 5 years without problem. I think I have also had a Thunderbird update also.

Can you advise any possible solution as to how to get Thurnderbird / gmail to accept my log file to send, please

I have changed my BT Internet ident password. My emails are accessable on BT Internet email but not on my Thunderbird software. I have changed the password for each of my three accounts but when I try to access my emails via thunderbird it tells me it is not recognised and asks for yet a new password. It also worked once and now has returned to 'no access' to my BT Internet account. Very confused. regards Graham Hadley
