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

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

I've been trying to add a new email address/account on Windows 11 with Thunderbird 143.0 (64-bit). I've never had an issue adding email addresses/accounts previously. . I continually get this error message: Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIMsgAccountManager.createIncomingServer]

I can log into this email account on roundcube (email client) without any issues using the same pword, but when I try to set up this email on thunderbird I get this error.

I get this error at the final "Enter Password" screen and can not finish the setup.

Thanks in advance for your help

I'm managing multiple email accounts in my Thunderbird installation. (Note: NOT multiple Thunderbird profiles, but things like a Gmail and an Outlook account under the same Thunderbird profile). I'm trying to remove an email account from the Account Settings menu, but clicking the red "Delete" button does nothing. I've opened up the Error Console/Developer Toolbox, and when I click the Delete button, the following error message gets logged:

``` Uncaught TypeError: can't access property "incomingServer", currentAccount is null AccountManager.js:894:18

   onRemoveAccount chrome://messenger/content/AccountManager.js:894
   oncommand chrome://messenger/content/am-main.xhtml:1

```

A screenshot of the menu is attached. Note that the "Account Name" field also stays blank for whichever account I choose, despite all of them actually having names and showing up in other locations in the application.

Hi,

Thunderbird: 142.0 (64-bit)

When I try to add a mail account that I deleted before, I receive an error message:

• Error Creating Account
• Incoming server already exists.

When I add my email account, I receive the message, "Can't find a server," and Thunderbird adds the incoming server configuration somewhere. It's not in the "Account Settings" menu.

I deleted my profile folder and started from scratch.

I tried to use the same configuration settings I have in the mobile version of Thunderbird, but without success. Unfortunately, it's not possible to import the settings from Thunderbird Mobile.

I have the same problem with the Account Hub, or without it. How can I fix this problem?

Many thanks,

Bonjour, J'ai déjà 2 comptes mail sur thunderbird : xxxx@xxxx.fr et xxxx@xxxx.fr Je veux en ajouter un troisième : xxx@xxxx.fr

Quand je vais dans paramètres comptes --> "+ Nouveau compte" --> Nom complet + adresse mail --> "Configurer"

Après le processus n'aboutit pas : un cercle d'attente tourne à l'infini sans jamais passer à la prochaine étape.

Bonne journée,

I have a working Thunderbird email account on a windows 10 computer. I recently bought a new windows 11 computer and downloaded Thunderbird from the Thunderbird site. I installed it on the new computer and tried setting up my email. It fails in auto and manual setup. Since I have a working account on the windows 10 computer, I should be able to look at the settings and transfer them to the new computer. I am 76 years old and have a difficult time with today's technology. If someone can assist me, I would be grateful and co-operate fully. Thank you.

                                                                                                             Stephen

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

Hi,

cannot find an answer. I would like to open TB with my default account which I did via account actions default. TB always opens with a different account. What can I do to make that happen? Thank you in advance

Hi All,

My name is Chris and I’ve been struggling for the past 3 days to add my Gmail account into Mozilla Thunderbird, and it’s become urgent. My computer often crashes and freezes, so I deleted my Gmail from an earlier version of Thunderbird and reinstalled the latest version.

When I try to add the account, Thunderbird just says “Looking up configuration of my Gmail” and never completes the setup. Oddly enough, I was able to add the same Gmail account into Outlook without any issues.

Is there something wrong with Thunderbird’s automatic server configuration for Gmail?

On top of that, I’d like to download all my past Gmail emails (sent items and inbox storage) into Thunderbird, but I don’t know the correct manual settings to use.

Any guidance on fixing the account setup and the proper manual IMAP/POP settings would be greatly appreciated.

Thanks in advance, Chris

Hello,

When creating a new account with the email provider @gmx.de, after entering my name, email address, and password, it is confirmed that this combination is found in the Mozilla ISP database. (1)

After clicking the 'Done' button (2), an error message is displayed (3).

I can log in to the email account using the same credentials via a browser.

What could be the cause of this behavior?

Thank you in advance for your assistance.

It says my sbcglobal.net settings are out of date. Pops up once a day. HOw do I update my settings for [edited from public] @sbcglobal.net?

I kept seeing a message saying my libero account had failed to connect to server even though messages were still coming in (and going out?) but then my sent Folder started having gaps and messages not recorded. I decided to delete the account before re-entering it. Now, when I try to renter the details the 'new' account fails to appear and there is an error message saying 'incoming server already exists. Perhaps I didn't cancel enough when I deleted - there were 2 options, I think, but how do I now delete this 'preexisting' server connection which is blocking me???
