I got an email from Microsoft saying my Live.com or Outlook.com email accounts won't be supported in Thunderbird UNLESS I change the settings to OAuth2 in incoming and outgoing server settings.

I even REMOVED the email account and re-added it making sure it was OAuth2.

But for my live.com & outlook.com email accounts I continually get prompts for passwords from Thunderbird. Sometimes I can't even click the RED X at the upper right to shut the prompt down. I just happens over and over until I give it what it wants.

I am tempted to shut down all Microsoft email accounts and switch to Gmail.

I have Thunderbird version 115.12.2 (64-bit) I used Windows 11 23H2 build 22631.3810 Windows Feature Experience Pack 1000.22700.1020.0

Any idea how to stop these prompts?

I like Thunderbird much more than any other email program I have ever used, and would like to keep it

I have no usable Menu options at the top of the Thunderbird email screen. I hit a wrong key yesterday and things such as Write, Reply, Print, Send, Delete, Junk, etc. have disappeared. I read some possible things to help but I do not have III on the upper right of my screen and pressing Alt when opening Thunderbird also does not work. HELP!

When I open Thunderbird (Mozilla), my files are not current. In other words, the most recent emails, probably since the last time I used Thunderbird, in my file folders are missing. I have tried changing the server settings but I think they are correct. Please be patient with me, I am unfamiliar with all the terminology, etc. Also, when I first enter Thunderbird, it does not recognize my password. A window opens with the message "Login to server imap.postoffice.net with username john.fn@usa.net failed." That message also appears when I click on Get Messages. Thanks for any help.

Hi,

I am a longtime Thunderbird user. I have 3 email accounts that I check via Thunderbird. I am having issues on just one of those accounts since the 115 Supernova update. I see the message "checking inbox for new messages" but they are not downloading. I have ATT email through Yahoo, and I can log into Yahoo Mail (webmail) and see the messages there ... they suddenly are just not downloading to Thunderbird.

I have tried:

compacting folders Thunderbird safe mode Windows safe mode with networking turning my antivirus off temporarily moving all emails in that account Inbox to a backup folder

I'm frustrated and need to download mail - can you please help me?! Thanks!

Tonight I accidentally mistyped my password upon starting Thunderbird, so I chose "enter new password" and retyped it correctly. But now it won't download my mail, and I can't find any way to try entering the password again. (My password is not saved.) When I click "Get messages" the blue progress bar flickers at the bottom of the screen briefly but the Activity Manager remains blank. No mail is downloaded and there are no progress messages. There is also a small "null" note at bottom left, not sure whether that's related.

I have tried restarting Thunderbird several times, and restarting my computer entirely. No difference. I went into Settings / Privacy and Security and confirmed that there is no password saved. None of the settings have been changed. But I'm not getting an error message when I try to download mail, it's not doing anything at all (aside from the brief flicker of the progress bar).

I tried sending a test message and got the error "Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) smtp.theworld.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again." But none of my settings have changed. I can access my mail via web server so there isn't a problem with the ISP. But answering mail that way is really clumsy and time-consuming. I need my Thunderbird!

I am using Thunderbird 102.12.0 with Windows 10 Pro. I have been a happy Thunderbird user for many years (since 2015 I think) and have never encountered this problem before. I really hope you can tell me how to solve it, I am aware of several time-sensitive messages in my mailbox and I can't download anything. Thanks very much for your time!

Hi, In TB 102 the menu toolbar was still above the button toolbar, if I am not mistaken. In TB 115 this seems to have changed... I could not find a way to customize it back as it was. Pointers anyone ? Thank you.

Starting on 10/01/2024 Thunderbird no longer allows me to send or receive email.

When I try to read messages using Thunderbird, I get the following: Sending of password for user XX@msn.com did not succeed. Mail server outlook.office365.com responded: Logon failure: unknown user name or bad password.

When I try to send messages using Thunderbird, I get the following: Enter your password for XX on smtp.office365.com:

I have tried redoing the password and it does not help.

This is on a WIN/10 system. I updated to the latest version of Thunderbird and it did not help.

I checked out Thunderbird on my WIN/XP and get the same results as with WIN/10.

When I use Firefox and login to https://outlook.live.com/mail/0/, I can send and receive email as before. The same is also true with my Mobile Phone.

Since update to ver 128.1.0esr the "new subfolder" feature does not work (does not show window to name new folder). I have many subfolders and I rely on them heavily. I tried restarting Thunderbird, then Windows. I ran in debug mode with no success. I downloaded and installed 128.2.0esr again. No change.

Is it possible to go back to the earlier version? Which is? Thanks, Frederick

Last night I created a new profile in an attempt to fix a problem with downloading mail. (It turned out to be on the ISP's end.) Tonight I briefly opened two copies of Thunderbird, one with the old/original profile and one with the new profile, to make sure the download would work. I was able to download my new mail to the original profile, so I moved last night's mail from the new inbox to my original inbox in the new profile, and then deleted the new profile since I don't need it. But now the past six months' worth of mail is missing from both my inbox and my sent folder! They both jump from June 13 to yesterday. I noticed it when I had the two copies open next to each other (those messages were missing in both copies), but thought maybe it was a merge problem and hoped they would be restored when I deleted the second profile. But they weren't. I absolutely did not delete all those messages and many of them are really important. Where did they go and how can I get them back? Help!!!

p.s. Sadly I haven't backed up in a while... :-(

TB working fine, then next day opens up as Blank screen and a setup tab Profile shows to be still there as do mail folders .... so need to recreate profile.

Created a new Profile I copied over the folders:

 IMAPmail
 Mail

and the following files

 key3.db
 logins.json
 cert8.db

and all of the pref.js files (1 through to 141)

The profile folder does show new profile active ( as per this pic https://flic.kr/p/2pjRyRz)

I created the 2 IMAP account login details, I now have access to the inbox for 2 IMAP account, but I do not have any the filed mail (local folders) how do I get these back. This is an important item for me as many years of filed emails.

I back up my TB profile every few months. I just went thru the Cox-Yahoo email conversion and I am getting emails. When I did my back up, I noticed in the properties it had one more folder and the files went from 1311 to 2585 files. Is something wrong? Do I need to compare and research what is causing this or just move on!

Is Mozilla working on the below email I have received from Microsoft? "The safety and security of your information is top priority for Microsoft. To help keep your account secure, Microsoft will no longer support the use of third-party email and calendar apps which ask you to sign in with only your Microsoft Account username and password. To keep you safe you will need to use a mail or calendar app which supports Microsoft’s modern authentication methods. If you do not act, your third-party email apps will no longer be able to access your Outlook.com, Hotmail or Live.com email address on September 16th.

What do you need to do?

If you are receiving this email, you are currently using an email or calendar app that uses a less secure authentication method to connect to your Outlook.com email account. You will need to upgrade your third-party mail and calendar app to a version which supports modern authentication methods.

Microsoft provides free versions of Outlook for your PC, Mac, iOS, and Android devices which can be easily downloaded and connect to your email account. Using an updated version of an Outlook application will ensure you are connecting in the most secure way.

How can you set up your Gmail, Apple Mail, or other third-party mail application?

Various non-Microsoft applications will have their own steps for connecting to your Outlook.com email account using modern authentication methods. See our help article - Modern Authentication Methods now needed to continue syncing Outlook Email in non-Microsoft email apps. However, you may need to contact the creators of those applications to provide you with instructions. In many cases, simply removing and re-adding your account with the latest version of that application will configure it to use modern authentication methods.

I was using thunderbird. I accidentally hit the sort by star right above the email list. The application crashed closed. When I reopen it, it immediately crash closes. I can't even get an pointer arrow for long enough to exit myself.

On window 10. Thunderbird was up to date.

Tried - restarting computer. Signing out of TB in the crash report box. Can't get into safe mode.

How do I correct my serious error (when tired) in allowing a Thunderbird 'Upgrade' 115.2.2 (32 Bit) Supernova to install on my Laptop (Windows 10 Home, 64 Bit). I failed to read the Release Notes by trusting Mozilla wouldn't issue such a drastic change without Warnings as it was not just an 'Upgrade'! It has screwed up my Set up, Folders etc., completely changed layout, can't find 'Write Message' tab etc. etc . etc.

The previous Thunderbird Version had many problems further introduced by 'Upgrades' but was at least still had continuity with earlier Versions with a functional MMI (man machine interface) instead of all the changes introduced with the 115.2.2, which in my opinion should be withdrawn completely. N.B My experience in Systems Control, as an Air Traffic Control Engineer, we would throw this out as not fit for purpose.

Help Please and explain how can I revert back to an Earlier Version?

Good morning, I had asked a question early on Saturday, but was unavailable the rest of the weekend so just now responding to associate Corey Bryan's answer. I had gotten a message that I am using an unsupported version and they recommend downloading the latest stable version. He said it appears that I'm on the "Release" channel and most likely want to be on the ESR channel. I also mentioned that I am a cave-man when it comes to anything computer and am very skittish about making any changes as I don't how to straighten out any errors that might occur. He asked me where I installed Thunderbird from and the answer is that I don't know. It was an IT guy that did it many years ago. So I guess my questions are, if I've been using this version for years, do I need to or should I update it? If so, if I click on the latest stable version of Thunderbird, will that change anything on my computer, aside from getting the newer version of T-Bird? And will my e-mails in Thunderbird look any different? Thanks very much for the help. Tony

I just upgraded to 128.2.2esr and cannot receive or send messages after the update. I have restarted the computer and tried again - still nothing. I'm unable to use a tool that is critical for my daily needs.

Trying to send just says "Connected" or "Sending" but never completes. Worked fine before the update which was just in the past hour or so.

Same issues with downloading new email or sending email for all accounts. :(

Anyone else having problems? Ideas?

Thank you!
