I can't add my personal @hotmail.com account to Thunderbird. Every attempt ends with "Authentication error – Unable to log in at server. Probably wrong configuration, username or password." All my other accounts (Gmail and several Microsoft 365 business accounts using outlook.office365.com + OAuth2) work fine in the same profile.

Setup

• Thunderbird 160.0 (64-bit) on Windows (problem also happened on 159.0)
• Settings auto-detected by the Account Hub: IMAP outlook.office365.com:993 SSL/TLS OAuth2; SMTP smtp-mail.outlook.com:587 STARTTLS OAuth2
• POP3 (outlook.office365.com:995 SSL/TLS OAuth2) fails in exactly the same way

What happens

• The Microsoft sign-in opens in my default browser, I sign in with the correct account (2FA), and I get the "You're all set" page.
• With mailnews.oauth.loglevel = All, the Error Console shows a successful token response from login.microsoftonline.com with scopes IMAP.AccessAsUser.All, POP.AccessAsUser.All and SMTP.Send, and "Creating new login for ...@hotmail.com". Microsoft also emails me "New app(s) connected to your account".
• Immediately after that, account setup fails with "Unable to log in at server". The console shows nothing more specific.

What I already tried

• Removed and re-added the account several times; cleared the saved OAuth logins for this address
• Cookies are allowed; mailnews.oauth.useExternalBrowser is back to true (setting it to false made the redirect go to https://127.0.0.1 and fail)
• In Outlook.com: IMAP is enabled (toggled off/on and saved). The address is the primary alias of the Microsoft account. Two-step verification is on. Recent activity shows no blocked or unusual sign-ins, even right after a failed attempt.
• Webmail works normally.
• Microsoft support says nothing is blocked on their side and sent me here.

Is there anything else I can check, or a way to see the actual IMAP server response to find out why it rejects the token?

I have just changed my Gmail password and now see this message when I log into TBird

I have installed Thunderbird to work with my spectrum email account. I had successfully installed it and was even able to recieve emails, but could not sent them. I uninstalled it, reinstalled it and now I can't receive emaill either. The settings for the servers and my username (fulll email address) all look correct per spectrum's website. Whenever I enter my password into Thunderbird I get:

"Login to server mobile.charter.net with username stynee@ca.rr.com failed."

Next steps?

I am trying to migrate my Thunderbird account from PC Windows 10 to a new PC Windows 11. The installation selects my provider and settings correctly but when I try and sign in, I get the above message. I have not the first idea where to start there. any help would be appreciated. I still have a copy on a windows 11 laptop that I can use to enter settings, but I can't get that far with the installation. Any help would be greatly appreciated.

Unable to log in at server. Told: Probably wrong confid, username, Password. Can't proceed, don't know what to do! Perhaps nearly there? Need your help. Thank you.

I rarely do any detail adjustments, if any, to Thunderbird so I am completely at sea on it! I have not been able to identify my Thunderbird version but must be recent.

I think I have managed to get almost there but need your help. I have so much to do but can't proceed with the work that desperately needs doing.

Your help would be much appreciated. I am not a natural PC worker, I have managed to extract myself from MS Windows because I don't need all their diverse complicated bits of software. I just want to get on and do the things that really matter. Linux, Thunderbird have been doing all I need. Using Linux and Thunderbird is a breath of fresh air Malcolm Sanderson.

For various reasons related to password confusion I decided to delete an existing gmail account from Thunderbird 153.6.0esr 32-bit. I then tried to open it again using the existing email address (having done this many times before with no problem).

But I get stuck at this stage as I am waiting for a popup and nothing comes. I've tried deleting history and cookies, changing browsers, checking OAuth2, etc as suggested in various places, but still I get this spinning wheel going on and on.

Any suggestions?

After upgrading from the previous ESR series (140.17.0esr) I can no longer access my mailbox, due to the OAuth2 authentication process failing.

As to items on https://support.mozilla.org/en-US/kb/thunderbird-and-yahoo: 1, 2, 4, and 5 I have double- and triple-checked. 3 is unclear to me: I'm unaware of anything hidden, yet at the same time I would have expected the site to ask me for a 2nd verification step (e.g. sending a numeric token to my mobile phone) after having entered my password. Whether that step isn't shown or whether the failure (see attached picture) occurs ahead of this I cannot tell.

Needless to say that this occurs at about the worst of all possible times, where I will need my private email much more because of soon losing my business one.

I am using Thunderbird 158.0 (64-bit) on Windows 11 and cannot connect a newly created Outlook.com email account.

The account works correctly through Outlook.com webmail, but Thunderbird consistently reports:

"Authentication error — Unable to log in at server. Probably wrong configuration, username or password."

I have spent considerable time troubleshooting this problem and have already completed the following checks:

Confirmed that IMAP access is enabled in Outlook.com.

Verified incoming IMAP settings:

Server: outlook.office365.com

Port: 993

Security: SSL/TLS

Authentication: OAuth2

Verified outgoing SMTP settings:

Server: smtp-mail.outlook.com

Port: 587

Security: STARTTLS

Authentication: OAuth2

Confirmed both usernames are my full new Outlook.com email address.

Confirmed that Microsoft lists "Mozilla Thunderbird" as an authorised application, with permission to read, write and send email.

Tested network connectivity using Windows PowerShell. Test-NetConnection outlook.office365.com -Port 993 returned TcpTestSucceeded : True.

Created a completely new Thunderbird profile containing only this Outlook.com account. The same authentication error occurred.

Tested Thunderbird Troubleshoot Mode without success.

Confirmed cookies are enabled and Windows is not using a manually configured proxy.

Removed saved OAuth2 credentials and retried authentication, without success.

Tested both external-browser and internal-browser OAuth2 authentication using mailnews.oauth.useExternalBrowser. Neither worked, and I restored the original value of true.

During an earlier attempt, the Microsoft authentication process displayed the error 127.0.0.1 refused to connect.

Microsoft's authorised applications page confirms Thunderbird has the necessary permissions, but Thunderbird still cannot authenticate. I have not successfully been prompted to enter my new Outlook.com account password through Thunderbird.

My existing Hotmail account works in Thunderbird.

Could this be a known Thunderbird 158 OAuth2 problem affecting newly created Outlook.com accounts?

As the usual configuration, password, permissions and network checks have already been completed, I would appreciate advice on identifying the underlying authentication failure rather than repeating those steps.

Thank you for your assistance.

I have the latest version of thunderbird. This has just started in the past few weeks. I have 3 separate emails that thunderbird handles for me. The main one seems to work fine but slow. The other 2 it keeps asking me to input the password for them. I don't know why because it never asked before. I input the password and it does not accept it for either accounts. why is this happening and how can I fix it. These are roadunner accounts. I know they are "legacy" accounts. We are switching to another email service but need to access the current roadrunner ones for a period of time to make sue we get everything switched over.

Any help will be appreciated.

Thanks Bob

I'm trying to re configure Thunderbird, to avoid the constant requests for passwords each time I try to send an email. My server sent me a link to a discussion of this problem, which listed several possible solutions to the problem. #3 and #4 did not solve my problem.

1. 2 suggests I delete the Tbird files logins and logins.json. I followed the procedure:

Menu/help/troubleshooting information/profile folder/open folder.

I found the two files, but I cannot delete them because "the files are still open". Where do I go from here? Please reply via email [redacted from community support forum] @pathcom.com

I am using the correct password but it keeps saying " Login to server imap.comcast.net with username [redacted]@comcast.net failed.". I hope someone can help. Thanks.

With Google traduction: I've changed my password four times using an Infomaniak email address ending in @ik.me, and it's never recognized! What should I do? Thanks.

I have multiple email accounts on Thunderbird (on MX Linux)... att.net, gmail.com and aol.com

While traveling without my computer, i had to reset my aol password on my iphone.

Now that I'm back at my desk, and being unable to find how to change the aol password on Thunderbird, I deleted the AOL imap account and have tried much of today to add a new AOL account.

In the past, I could create an 'app password' within AOL (browser) and use that password in Thunderbird... but that is no longer working.

Any guidance/suggestions?

I am running the latest Thunderbird version 140.17.0esr (64-bit) available in my MX Linux.

I already have Gmail linked to Thunderbird on Windows but now have a Linux computer. When adding Gmail, I am taken to Google's website as expected which grants authorization after satisfactorily logging in. I'm sent back to Thunderbird that then displays Authentication failure. There seems to be no way around this despite looking for any Google credentials in saved passwords. Thunderbird has added other mail accounts with no problem. Google will show that my Linux computer is linked but Thunderbird rejects any attempt to sync with Gmail. I'm wondering if there remains any Google data within T'bird that is corrupted that needs to be cleaned out to start over fresh.

I keep getting a pop-up message from https://s1021.use1.mysecurecloudhost.com requesting my username and password for one of my accounts. I enter both, I still have access to my accounts, and still the pop-up recurs. How do I resolve this??

I was trying to login to Facebook on a windows 10 laptop using Firefox. After repeated attempts I received the message that Firefox/Facebook uses containers and to enable containers I needed to login to my Firefox account but even tho I pasted the code sent to my email it won’t let me login. How can I login? I have my recovery key if I need to input that. ThY!!

My email, in and out is not working.. I need my current Mozilla Thunderbird Primary Password. Then I could continue to use it OR select a new replacement for the current one. How do you get this message? You can reach me by phone # [redacted phone# from community support forum] This is a land line. I don't use Text.

Program : Thunderbird Build - 115.18.0 esr .

How to reproduce:

Log into outlook.live.com an ensure IMAP is enabled.

Start Thunderbird and create a new 'mail' account manually, given the account settings provided by outlook.live.com. (https://support.microsoft.com/en-gb/outlook/pop-imap-and-smtp-settings-for-outlook-com)

The account may have to be setup manually.

Also you may have to setup the outgoing SMTP server to use OAuth2 manually as an SMTP server directly, as the normal dialog presented during manual setup did not provide this option unless the servers were set up indvidually.

The e-mail account details should be set up.

What should have happened:

SMTP server should have permitted Ouath2 authentication during setup. Thunderbird should have presented a login to obtain a password, and retrieved messages to a local inbox.

What actually happened: "Authentication failure when connecting to server outlook.office365.com"

Possible causes :

• Build not actually supporting Oauth2 despite claiming to.
• Third party server is claiming to support IMAP/Oauth2 but refuses to recognise credentials sent by Thunderbird.
• Build too old.

Thank you.
