My Thunderbird set-up has worked fine for years so I was surprised to discover two days ago I can no longer send emails. I have a Gmail SMTP account which I have never previously have a problem with.

Thunderbird updates automatically and I am on version 91.8.1 - it's possible the problem began when the new version was downloaded but I don't know when that was.

Whenever I try to send an email I get the error:

The message could not be sent because the connection to Outgoing server (SMTP) smtp.googlemail.com timed out.

On May 20, 2022, in a few days, Google will turn off "unsecure access" to Gmail from Thunderbird and Outlook. This will require changing the Thunderbird account settings from "Normal Password" to "OAuth2" for verification. Problem is OAuth2 verification will not work on my Windows 7 laptop. It just runs in circles. A Google page opens, asks my Google account password, accepts it, and then shows a page asking to allow access to the account. Saying yes just closes the window, but no mail gets POPed down to Thunderbird. In my testing, OAuth2 does work on my Windows 10 laptop. If you are as stubborn as me about still using the Win7 computer, you can change your Google account to use 2-factor verification. They will call you or text you every time you log in to the Google account itself, or you can buy a USB dongle. Once you have 2FA setup, you can go to the "Security" sidebar in your Google account, and create an "app password". I said "Mail" and "Windows Computer" and it generates a 16-letter password shown as all caps, but when cut-and-pasted in my Keepass password manager is all small case. You can then go back to, or stay at "Normal Password" in your Thunderbird account settings, and when the password to your Google account fails, put in the app password and check "Remember in Password manager". Then you can POP emails from Gmail again. I don't know if Outlook has these problems. I assume IMAP on Win 7 might have these problems. I did create a new T-bird profile just to try this out. I detailed that misery quest in a previous post: "Almost can get Gmail with 2FA" https://support.mozilla.org/en-US/questions/1369836

The sad thing is my Google password is 15 characters alpha mixed with numeric, I assume case sensitive, and also special characters. So it is much more secure than the app password Google assigned me. Especially more secure now that hackers know our email password is 16 alpha non-case-sensitive. Oh well, that's Google for you. Don't blame them, blame the idiots that set their passwords to Password1.

After figuring out this with the new test Google accounts I made, I just switched one of my three "real" Gmail accounts to 2FA, and an app password for mail. If I read right, if you try to outsmart the system and drop out of Google 2FA, it also invalidates all your app passwords as well.

It would be nice if the T-bird team could see why OAuth2 verification fails in Win7. I posted results in my T-bird error console in that previous post. I hope this is a weird thing that only affects me, but just in case, I thought I would post this for other Win7 dinosaurs out there.

Hi, I'm using Thunderbird chat with XMPP and Openfire as XMPP server. My only problem is that I can't transfer file on chat window. However, I can easily send files on other XMPP client such as Pidgin or AstraChat.

So, my question is, does Thunderbird chat support file transfer ?

Thx

I posted this question yesterday and received one reply, which I have rejected, but there was no way to respond in the thread so now I have to re-post the question. So that is yet another problem, why is there no way to respond in the thread. First question, I need a real answer and solution to the disappearance of my TB thumbnail icon under Start-Programs after agreeing to do an update. The first reply was to reinstall, which is not a solution in my opinion. I use many software's that do regular updates, and none have killed the thumbnail icons so this is a TB problem not a Windows problem. Secondly, I have spend over a week getting TB to function as I need it to function and to properly accommodate my email addresses. I really don't need to risk losing these efforts to a reinstall, and given my experience thus far, I don't trust TB to not kill my custom setup during reinstall. I am willing to work with TB developers but this kind of response is rather insulting frankly.

The reason I am here is because I am worried about the insecurity on internet. I have been using it for years but now I realize every single person is vulnerable. I honestly did not know how easy they can steal your information from your computers, or any device you use to surf on the web. And that is not right. I think that situation has to change and if there is any way I could help to generate a change i am here.

I have a picture of the hackers and I called the FBI AND THEN THE SHERIFF DEPARTMENT OF ROWAN COUNTY AND THEY DIDN'T TAKE IT SERIOUSLY, I WANTED THEM TO TAKE FINGERPRINTS AND THEN TO DO DNA TESTING AND THEN I KNOW THAT THEY WOULD BE IN JAIL FOR B&E FOR MY GARAGE 5-7 TIMES AND THEN I'M SURE THAT THE HACKING WOULD BE FINISHED. EVERYTIME I LEFT THE HOUSE THEY BROKE INTO IT SO I ALREADY BOUGHT 3 DIFFERENT SURVEILLANCE SYSTEMS AND THEY ERASED THE FOOTAGE BY USING A MAGNET
