Cannot get rid of TB's request for account password/connection for an account that I removed. Server account deleted, saved passwords for this account deleted. All references to this account that I know about have been removed and still when I open TB it pops up with request for username and password for this deleted account. Please help.

I'm trying to add a second email account from my domain into Thunderbird and on the password test page I get an error. Of course the server exists, my other email account also uses it. How do I fix this or is this a problem with Thunderbird?

I use four eMail addresses - outlook.com, att.net, and two gmail.com. Does Thunderbird support the import of all four into one place? A one-stop-shop, so to speak.

ld-1@att.net

Attempting to add a gmail oauth account in TB fails authentication using verified account password. (The account requires two-factor authentication using an authenticator app, but haven't tried that as a password) I have removed the account from TB, and the saved passwords for the account. I then added the account back to TB but get the same "Failed authentication" notification without any opportunity to register a new password. I can not find a cookie to remove and retry the process.

with some changes with a default search for passkeys, I am no longer able to use thunderbird mail as is, as after spending three hours today, I was unable to add a 2nd account that has been accessed via gmail for a long time. I am wondering what other email problems other than thunderbird might have similar features,. as thunderbird has been rendered unusable by new code/passord, passkey requirements. I was looking at spark, but their interface is not as helpful. Thoughts! RIP Thunderbird mail, a long time friends, but time to move on, alas

When I click on a mailto: link on websites, it defaults to an old email address that I am phasing out. So every time I click on a mailto: link, TB opens a new email using the old email address, and I need to remember to click on the list of my email accounts and select a different one.

How can I change the email address that is the default?

Thanks in advance! Clint

I have an unfamiliar name on my Thunderbird account of g*******k@hughes.net (I do not know this account) and I am able to see the inbox of this email on my computer in Thunderbird. I have been working with Hughesnet as I was without email service since 11/17/25 and have just been able to now Receive emails since 11/25/25, but am unable to SEND outgoing emails. Hughesnet requested that I contact Mozilla support as to the outgoing email issue - and the unfamiliar name on my Thunderbird account. Please help with this situation. My email account with Thunderbird is t****k@hughes.net

Hi, I've got a "confirm your account" email, which I click through to get to my account but from there I don't know what to do to verify it. Is there a "verify" button that I'm missing, or an action I need to do on my account in order to finalise it? Thanks

I'm just getting set up with Thunderbird. I used to use Postbox, and imported my Postbox profile into Thunderbird, which overall worked great – it got all my local email folders, and brought in my Apple email account, and so forth. The only wrinkle I've noticed so far is that it also created an account named "server7.invalid" that I can't delete. If I go to Account Settings, for "server7.invalid" it states "The following is a special account. There are no identities associated with it." The only items underneath it are "Spam Settings" and "Disk Space". There is no red Delete button for it, the way there is for my two real (IMAP) email accounts. Viewed on the Mail tab, it appears to contain only "Trash" and "Outbox", and both of those are empty. This weird invalid account doesn't seem to be doing any harm, but of course it is ugly and I just want it to go away. Help?

Hi all,

I have tried on K9, and Thunderbird Mobile.

On my tablet, with K9 mail, I exported my fully working accounts, and imported to my phone. All worked, except one account, where it only has an outbox. No inbox, no sent folder, nothing.

I then Installed Thunderbird mobile, and used the QR code link in the desktop app, to sync to it. Same issue. All other accounts work fine, but not that one account. Only an outbox.

I've logged into the web version of that account, and no restrictions are on folders. And it's only on my phone. On tablet it's fine.

I can't even choose folders in settings, for sent, etc, as there are none to choose.

Any help would be greatly appreciated. Thank you

Hello,

We have installed Thunderbird version 144.0.1 on a new computer. We successfully created one email account, but we are unable to add another one.

When we try to set up a new account by entering the name and email address and then clicking Continue, the process stops and does not go any further.

Please find the screenshot attached.

Thank you in advance for your help.

Best regards, Ana Jovanovic

suddenly the Thunderbird cannot distinguish between info@zelec.se and info@stiernbrandt.com. It thinks they are the dsame and if I write the email address in the "Edit SMTP server" as info@zelec.se the same name appears in the account info@stiernbrandt.com. This is a very recent error. I saw todfay that this happen and then TH forbids me to send email from info@stierbrandt.com since it wrongly copies the into the info@zelec.

Hello, i have three PCs with installed Tunderbird. On one of them i want to add a new mail-account. If i follow the instruction here: [https://support.mozilla.org/de/kb/automatisch-konto-konfigurieren#thun...], it leads to an input mask (not a Tab!!!), where i can enter an account-name and the mail-address. Clicking on Continue some automatic search is started but never stops (=> screenshot).

As i tried to do it several times now and tried to find other solutions, red instruction etc., i write now. Also: Im not sure if it is a bug.

I already mentioned in the beginnig: I have three PCs here. I used one of the others compare, wehere it works as described in the documentation (not an input-mask, but a Tab). So the probem occurs only on this PC, not on the other. Systems: Not working on win11 Thunderbird 144.0.1 (64-Bit) Working on win10 Thunderbird 144.0.0esr (64-Bit)

Mozilla automatically put in the necessary info for an xfinity email account and said it was accepted, but I don't see the second account in my email program. Can you help?
