Hi,

I'm trying to add another account to my Thunderbird client (already have 2, a IMAP account, and a Hotmail/Live/Outlook), but i keep getting the error "Exchange auth error" and no possible way to manually configure the server or anything, despite the mail server not being an exchange server. Following this, it just freezes the view, although i can close the popup by pressing escape.

is this a bug in the most current version of Thunderbird, or am i doing something wrong?

Did ask forum for help on 12/9/2025, and though there was some info on line to solve my problem, I was unable to understand it, or proposed solutions did not work.Tried now to log into mozilla account, but cannot find any section about any replies. As problem driving me crazy, will try again.

1 When emails come in, instead of the sender being shown in the from box, it gves me at pethen.riseup.net as the sender. 2 If i click on any link in the text of the email which I need to access, this function does not work. All that appears is the link text I click on gets surrounded by a text edit box (ie a thin square line with small boxes you can put an arrow on to change shape of box for editing 3 a yellow banner appears at the base of any email reading " a unique identity matching the from address was not found. + "the messagewill be sent using the current from field and settings from identity peter hendry<pethen@riseup.net> 4 My other emailaddress linked to my mozilla thunderbird client has no problems. This has to be such a simple problem relating to the account set up which for some reason my PC has taken into itself to change, either text in my address books do not match, or I have ticked a wrong bos in the setup, or not ticked one at all,

Please can any help this struggling man! Peter

Hi there, Cant add a second account to TBird on new installation on new PC with WIN 11. Works fine on WIN 10 and LINUX Mint but fails authentication on new WIN 11 PC. First account goes on OK but cant add a second. Have checked all setting but cant see a problem. Please advise. Thanks John

Why is TB duplicating local folders and then why I can't delete those duplicates. The only valid one is the highlighted one in the attach image.

And the message filter are not working properly?

Win10Pro

I am currently using Thunderbird v 140.3.0esr.

I had recently started getting a pop up message for my yahoo a/c. The message goes ' Enter credentials for email on imap.mail.yahoo.com' and below it was a message 'too many attempts' it does not let me enter any information. If I copy the address in the message header into a browser it only brings me back to the pop up. It only pops up for this particular email account and not for any other ones installed.

I have tried changing the password through settings which hasn't made any difference. I can go into my account through a web browser which does not show any problems with external accounts.

I tried deleting the whole account line in password manager but this had again made no difference and I still got the pop up. I then deleted the whole account to re-install it again but it is failing to re-install as it gets stuck looking for the configuration settings and goes no further.

I have tried re-installing off line and it immediately finds the settings but I can't go any further as I need to be on line and to do that I therefore have to cancel the application.

Any help with this would be appreciated.

Regards JL

TBird keeps asking permission to connect to a gmail account I no longer use and is supposed to be deleted by Google. I keep selecting Deny but it continues. I have a new gmail account I've been using for over a month and this just started. I deleted every reference I can find to the old account but all to no avail. Suggestions welcomed.

I have recently updated my PC and I have re-installed Thunderbird. However, Thunderbird will not allow more than 2 GMail accounts to be set-up. I get Unable to log in at server. Probably wrong configuration, username pr password. It is a gmail account, so the system automatically recognizes it. I have made double and triple sure that the user email and password is correct. I have even made my password smaller to ensure it is not the length of my password that Thunderbird has a problem with. Furthermore I have made sure that the outgoing server label is also unique. Despite all that, I am still unable to add a third Gmail account. Can you please help

I am using Thunderbird 140.0.1 (64-bit) for Windows and with this update there is a new account windows sety up. When adding a new account it only asks me for the email address and when I press continue it I get a blue circle going round and round and no progress. In previous versions I would input the email and password and this would work.

I can't add an account. When I try to add an account, I get an error message: can't access property "cleanup", this[#configVerifier] is undefined The version of Thunderbird is 140.0.1esr (64-bit).
