I have been using Mozilla Thunderbird for decades and they have even contributed a small amount of money to Thunderbird periodically. Just within the last two or three days all of a sudden I have been unable to send emails with my phone. I receive emails, but I do not send them.

So I opened up a laptop where I did not have Thunderbird and set it up properly through Spectrum using the incoming and outgoing servers as mail.twc.com. and yes, just like on my phone. I continue to receive new emails, but even with the laptop I was unable to send an email.

I received the message"send message error sending a message failed. The message could not be sent because the connection to outgoing server smtp mail.twc.com was lost in the middle of the transaction. Try again."

I contacted Spectrum twice and both times they had me try to send a message through their Web server spectrum.net and that message did go through. Of course then their response is that this has to be a problem with the third-party app meaning Mozilla Thunderbird, and they can’t help with that at all. I sure would appreciate some help because I hate to walk away from Thunderbird as well as change my email address after all of these decades.

Believe my T-bird account has somehow been corrupted. Takes forever to load on PC and always puts new emails in Trash folder. Often does not accept correct password. If I save / backup PROFILE, uninstall T-Bird and delete any Thunderbird folders on PC, if I restore per backup, will I be restoring the corrupted app. Don't want to loose email addresses, thousands of emails and email folder structure. Will a restore work? Thank you. Greg D

PS Version of T-Bird on laptop still puts all new email in Trash, but loads much more quickly, etc.

Hi!

I'm losing my mind by the fact that you can't hold to scroll or click to toggle scroll with MMB in Thunderbird, instead it opens a new tab which is completely useless to me since I share inbox and mail reader in one screen.

Is there any way to fix or change this?

If not I'd really like to request this as an option or feature.

Hi

When Thunderbird is started maximized it overlap taskbar if is set to hide and taskbar won't show until Thunderbird is minimized and maximized. Another way is to press the Win key two times. Then the hided taskbar can be shown/use. The same thing happens to Firefox. Only when is first started. Then if Firefox is minimized and maximized, press Win key two times, press F11 two times then the hided taskbar show/hide normal.

It is a setting that can be changed to start Thunderbird and Firefox in full screen and do not overlap hided taskbar?

I got a new computer, and after installing Thunderbird, it took forever to get it set up with the information from my old computer. Now, the unified folders aren't working. All of my mail is going into each account's inbox. There's no option to choose anything on the unified inbox, only the same thing as the other inboxes have. Help, please!

Normally, I can right click and tell Thunderbird that this is NOT junk, however, when I do this, these emails go back into the inbox and virtually instantly return to junk.

This is from anyone's email address that arrives from one particular website: @legacydigitalagency.com

I haven't come across this issue since I started using Thunderbird 20+ years ago.

It appears how TB handles IMAP connections for outlook email accounts no longer works - OAuth2 connection flow broken, and this is likely due to stricter changes made on Microsoft's backend that is impacting connections going forward.

I have multiple email accounts configured and recently, I have been bombarded by login pop up - likely related to the OAuth2 authentic process.

Whilst I was able to circumvent the authentication process - i.e. not completing the flow process entirely as it expected, newly created outlook accounts appear to reveal two things:

1] There has been a recent change to the authentication process - i.e. the telling sign.

2] There is a now deeper issue when trying to connect outlook email accounts. It seems the reason why circumvention was possible with existing accounts was because they have already passed the OAuth2 process correctly - correct tokens exist. Since this won't be the case for new outlook accounts - no OAuth IMAP access token created, above error is given.

It seems the likely cause is because Thunderbird holds or requests a token that does not contain the correct IMAP audience/scope combination, and Exchange rejects it during SASL XOAUTH2 bind.

For your information, I am using the latest versions and able to configure Apple Mail client - which uses Exchange protocol (not IMAP), without issues.

I have been using Thunderbird for ages now with no problem, but I suddenly realised that no recent emails were appearing from my Gmail account. I have tried everything suggested on line to resolve the problem, including uninstalling and reinstalling Thunderbird, and deleting and re-entering my acccount details but neither the IMAP or SMTP servers will connect to Gmail. I have reset all of the server settings on Thunderbird, and have checked that Gmail is IMAP compliant (which, apparently, is is now automatically). I have spent hours trying to sort this out and am just at the point of abandoning Thunderbird completely, but I am loathe to do so if there is a solution. The latest error message i have received is "Unable to log in at server. Probably wrong configuration, username or password" but I don't know what else I can check or change.

Hi, somehow thunderbird forced me to use OAuth for caldav and carddav. (v140 on linux) Unless I've probably missed something this approach doesn't seem to have considered that people might use more than one device. In the past I had an application password per device with my mail provider. That password covered imap, smtp, caldav and carddav. The application password I could set with a specific name at my mail provider. If the device was lost, compromised or whatever I just deleted that one application password at my mail provider, problem solved.

Now a regular thunderbird setup has the application password for mail and 2 OAuth records per device under "Connected Apps" at my mail provider. But it is not possible to see anymore to which device the OAuth record belong, as there is nothing device specific coming along with these OAuth records, just an IP.

With that perspective OAuth weakened my security options, as I can only guess which OAuth record I have to delete in an emergency case. Did anyone who implemented that with Thunderbird considered that people may have more than 1 device? Maybe even more than 5 devices?

That OAuth approach looks unmanagable to me. Is there a way to switch OAuth off in thunderbird, until it becomes more useable in >1 device setups?

Hi!

I can't get messages from my Thunderbird account. When I click "Get messages" nothing happens and it usually says "Done" on the bottom left corner. I have to use my domain's webmail account to get my e-mail and it only allows me to read it and delete junk.

I really would love to have my Thunderbird account working again as soon as possible.

Thanks so much, Nancy Pedersen

In the latest version 148, the moment I enter the login credentials for a second Yahoo account and click continue, Thunderbird simply copies the mail folders from the first Yahoo account and does not show the mails/folders for the second yahoo account. This is despite the fact that Thunderbird displays the correct name for the second Yahoo account as well as the correct username for the second Yahoo account in the account settings. I have tried: 1. Setting the 'mailnews.oauth.usePrivateBrowser" to True in the Config Editor. 2. Deleting and adding the second Yahoo account after restart of Thunderbird as well as restart of the PC. 3. Manually configuring the account settings while adding the second Yahoo account.

Please advise what else I can try. Thanks and Regards

I have a Windows 11 operating system. I tried browsing/uploading a couple email messages describing providing more information but wasn't successful. Can you help me ?

In our organization we have moved from an on-premise mail server to M365. We've also added our new EWS-based accounts to Thunderbird. Since there are a large number of users with a significant amount of older mails they want to have access to, they have been asking how they could upload them to EWS now.

From the looks of it, using TB one can either drag and drop messages from the local folders to EWS. Would message copy/move from the local folders be faster if the EWS account was setup over IMAP, instead of over EWS? If so, we could setup another account corresponding to the same EWS identity, but over IMAP, just for the purposes of transferring messages faster.

Thanks in advance for any information provided.

Prior to TB 148, OAUTH worked for POP3 access to: Gmail, MS Outlook, and Yahoo.

After TB 148 upgrade: OAUTH to Yahoo fails, subsequent log-in page also fails. Both OAUTH to Gmail and OAUTH to MS Outlook still work fine.

Rolled-back/Reverted to TB 147.0.2 -- OAUTH to all works fine, as it did previously.

Note: YahooMail seems to have other problems. But I was able to confirm successful OAUTH and POP3 to YahooMail after reversion to 147.0.2.

Can not send emails to a newly created outlook.com (free) account. Have tried dozens of different settings, approaches.

My current setup:

 - windows 10
 - thunderbird 140.8.0esr (64-bit),  numerous previous versions also do not work
 - outlook.com (free) account mail provider
 - POP3 enabled (tried IMAP enabling also) on outlook.com account
 - no 2FA or 2FA enabled on outlook.com account, no difference
 - outlook.com web access works fine
 - followed instructions in mozilla support article Microsoft OAuth Authentication and Thunderbird in 2024 
      (https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202)
 - have done a fresh install on a new machine without an existing profile.
 - have tried various microsoft servers, have tried oauth2, normal password
 - thunderbird account creation works just fine.
 - server settings and SMTP settings match as recommended by support article noted above
    SMTP server settings
        server name: smtp-mail.outlook.com  
        port: 587
        connection: STARTTLS
        authentication: OAUTH2
        user:  xxxxxxxx@outlook.com

symptoms:

 - receiving(downloading) emails works fine.
 - sending emails fails with following messages
     Login to server smtp-mail.outlook.com with username  xxxxxx@outlook.com    failed    followed by 
           Unable to authenticate to Outgoing server (SMTP) . Please check the password and verify the 
             'Authentication method' in 'Account Settings | Outgoing server (SMTP)'

Many people seem to be having this issue with no resolution.

Please help.

This happens each time I open up T-Bird. Somtimes it is Yahoo.mail, sometimes it prompts to log onto aol.mail.com.

How can this be stopped?

desktop Win11 pro Thunderbird 148.0 (64-bit)

Hello! The other day everything worked as usual, and I shut down the computer for the night. The next morning, Thunderbird immediately crashed/shut down when starting each of the 2 profiles I always use. The 3rd profile, which is the default-release running a different email, still seems to work normally. Thunderbird 115.10.1

I have tried Windows (10) safe mode, as well as thunderbird Troubleshoot mode and working offline, but the issue continued to occur.

I'm at a loss now as to what could cause 2 profiles to suddenly cause it to crash. By the way, one profile is for a gmail account and the other one is for an Outlook account, so they don't seem to be related.

In case it helps, there were 2 Microsoft Visual C++ programs installed or updated, and updates to Microsoft 365 and Google Drive just before the problem started. These were all auto updates in the background.

Any help from the Community would be greatly appreciated. Thank you!

re: OAuth2 Authentication for Yahoo, AOL and ATT

My settings selections don't really follow your help descriptions to the letter,so..., also, I already have 2 accounts on 2 platforms and they seem to already be configured with SMTP outging servers using OAuth2.

I'm confused since I'm now on 140.8.0 and have not needed to change a thing, contrary to expectations set from T-bird app popup warning and Mozilla article.(?)
