Thunderbird Support Forum

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 multiple work email address with outlook.office365.com, and one of them just decided that it won't logon for me today, error reads as below:

"Sending of password for user jeffery@ausilk.com.au did not succeed. Mail server outlook.office365.com responded: Logon failure: unknown user name or bad password."

prior to this issue occuring, I have not done any changes to my password or anything on outlook.office365.com and my login still seem to work on outlook.office365.com. Further more, my colleague who also uses thunderbird also encountered the same issue. However, this seems to only affect my thunderbird, and nothing else, my mobile device as well as outlook (windows mail) seem to work fine and can login using the same password.

I changed the password on outlook.office365.com and consequently on thunderbird and windows mail, and still, windows mail works, but not thunderbird. As a side note, my other outlook.office365.com mail box works absolutely fine with thunderbird, can send and receive with no issue, just this one, and it happened out of the blue. The last email I managed to receive before this issue occurred was at 11:30 am Sydney time GMT+10, as the next email that came into my inbox (on windows mail) was 11:37am Sydney time GMT+10.

Please assist, thank you.

I have set up my TB profile so that it is on an external SSD, but the program itself is on the computer. The reason I have done this is so that I can move the SSD from computer to computer (desktop to mobile laptop for example), attach the drive and access my e-mails using TB from different machines (each machine having its own TB installed).

I use POP3 to download my messages onto the SSD and periodically delete them from the Google server. This is why it is important to have only one data store for my e-mails (I keep them for years).

I have this working fine from my desktop, which was the original place I set up my e-mail. When I attach the SSD to my laptop and run it on the computer, I can see all my previously stored e-mails etc. but the connection to Gmail to download new messages doesn't seem to work. I do not get any error message, but neither do my waiting e-mails get downloaded, even if I explicitly request this.

My suspicion is that the issue is that I have 2FA on the Google login, and so TB can't access the Gmail server. I want to keep 2FA for security reasons. Is there a way of setting up (presumably unique) 2FA on both machines (presumably other than on the external drive) but so that each TB installation accesses GMail via its own 2FA, but stores and views e-mails from the external drive? Or is there some smart workaround?

TIA.

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

im getting this error. Please see attached. Everything is find from these emails when i send from sync gmail (on outside accounts) or straight from the host email server. But when i input into thunderbird i get this error.

everything was also find too before we entered our email signature. Now its not working.

please help. We need this for our biz

Hi, been using Thunderbird for decades and been of Office/Microsoft 365 for several years.

All of a sudden TB demands I re-enter the password? Enter correct password but goes into a loop. Check passwords in Passwords and they are correct. Logon to Office 365 manually and they work. Use e-mail with Outlook and all OK. Change the password but it still happens.

Was on TB 91.11.10 and upgraded to 102.0 (both 64 bit) but it has made no difference.

TB has got itself into a loop. What is wrong and how do I resolve this?

I can view my existing password but when I edit it to change it the new password is typed in and change saved but can no longer access email. Program is closed then reopened, computer is shut down then restarted but to no avail. HELP!!! Please. Thank you. Kevin

New Windows11 computer. Old computer inop. Thunderbird user and installed on the new machine but TB not recognizing my password. The onboard password recovery doesn't work for me because it doesn't yet list mine as a previously accessed account because this is a new install on a new machine I guess. I've tried many password attempts with no luck. Is there another way I can retrieve my old password? Tnx in advance for any help. B.

Hi. For no obvious reason, I can’t send or receive emails on my laptop or iPhone using my hotmail account? I received a message from Microsoft about unusual activity and my emails had also stopped working? I change my password by logging into Microsoft to do it and I can send and receive emails through that route but Thunderbird still rejects me from doing the same even though I have a new password. I typed the new password into my account on hotmail but it says imap doesn’t support passwords? My hotmail email is wmmajor@hotmail.co.uk Can you help? Mr W M Major.

Since today, we experience an unusual problem in Mozila Thunderbird. The program ask for the password for the email that is already sign in. And if we enter the password, it ask for the password again. The error is "login to server outlook.office365.com with username failed". Our company need to solve this problem because we use Mozila Thunderbird for over 100 employee.

Thank you!
