I believe since your last update, every time my phone switches a data provider, meaning goes from cellular data to my Wi-Fi or vice versa. Or if you go to airplane mode and then come out of it I get the Gmail authentication error. Every single time. I'm running Samsung Galaxy s23 running the latest version of Android 16. Has anyone else had this issue? I find it hard to believe that I would be the only one. It's getting really annoying having to keep clearing it or going in and then when you go into go through the settings it tells you it doesn't work. Any help would be appreciated.

Trying to add twc email to this email manager first said UN /pw not correct , finally changed password still not going thrgoogle states change email charter area to mail.twc.com still won't go thru. Twc is my main email so if it won't load up I'll have to use something else what else can I do? Thanks Lora

Since the last update (I am running K-9 Mail v17.0 on a Moto G Stylus 5G 2023 with Android 14 Build Number U1TGNS34.42-86-4-5-4-8), I am often getting a separate notification for every new email in my In Box (POP3) instead of one notification to say that I have a bunch of new messages, and the notification(s) is(are) not going away after I look at my message(s) and delete the email(s).

Any idea if this is a bug or a feature? It is annoying to delete 10 emails and then have to delete 10 notifications about the same 10 emails.

Thanks in advance for your thoughts.

Here is a complete **A–Z guide** for setting up an email account in **Mozilla Thunderbird**:

1. 1. 🦅 Mozilla Thunderbird — Complete Email Account Setup (A to Z)

---

1. 1. 1. **A — Open Thunderbird & Access Account Settings**

Launch Mozilla Thunderbird. For a new install, you will be automatically prompted to enter your existing email account details upon first launch.

---

1. 1. 1. **B — Gather Required Information First**

Before starting, have ready: - Your **full email address** (e.g., you@example.com) - Your **password** - Your **incoming server** (IMAP or POP3) hostname & port - Your **outgoing server** (SMTP) hostname & port - **SSL/TLS** or **STARTTLS** encryption type

These details can be supplied by your email provider. [Mozilla Support](https://support.mozilla.org/en-US/kb/manual-account-configuration)

---

1. 1. 1. **C — Add a New Mail Account**

At the bottom of the left pane in Account Settings, click the **Account Actions** button and select **Add Mail Account…** [Mozilla Support](https://support.mozilla.org/en-US/kb/manual-account-configuration)

In the Mail Account Setup dialog box: - **Your Name** — the name that appears on the "From" line in outgoing messages - **Email Address** — your full email address - **Password** — your email account password [Microsoft Support](https://support.microsoft.com/en-us/topic/set-up-email-in-mozilla-thunderbird-8-0-f4726a9e-64d3-4494-9260-5762597fd1a6)

---

1. 1. 1. **E — Auto-Configuration Attempt**

Click **Continue**. Thunderbird will check if your webmail provider is available in its database and provide available configuration options. IMAP will be the preferred setting in most cases. [Mozilla Support](https://support.mozilla.org/en-US/kb/automatic-account-configuration)

---

1. 1. 1. **F — Manual Configuration (if needed)**

If auto-detection fails or you have a non-standard configuration, press **Manual Configuration** and edit the server names, ports, and IMAP/POP settings manually. [Mozilla Support](https://support.mozilla.org/en-US/kb/manual-account-configuration)

---

1. 1. 1. **G — Choose Incoming Protocol: IMAP vs POP3**

IMAP (the more modern protocol) allows you to store messages on the mail server and on your local machine at the same time. The POP protocol only allows messages to be stored locally. [Mozilla Support](https://support.mozilla.org/en-US/kb/automatic-account-configuration)

Common IMAP settings: | Field | Value | |---|---| | Protocol | IMAP | | Port | 993 | | SSL | SSL/TLS |

Common POP3 settings: | Field | Value | |---|---| | Protocol | POP3 | | Port | 995 | | SSL | SSL/TLS |

Click **Re-test** to test your manual settings; there should be a quick response indicating the settings are valid. [Mozilla Support](https://support.mozilla.org/en-US/kb/manual-account-configuration)

---

1. 1. 1. **K — Authentication Method**

For modern providers like Gmail, Outlook, Yahoo, and AOL, **OAuth2** is used. An OAuth2 window may pop up for modern Outlook accounts — approve the permissions when prompted. [TechyDen](https://techyden.com/thunderbird-email-client-configuration/)

For app passwords (e.g., with 2FA enabled): Go to your Microsoft Account Security settings, find **App passwords** under "Additional security," generate one, and use it in Thunderbird instead of your regular password. [TechyDen](https://techyden.com/thunderbird-email-client-configuration/)

---

1. 1. 1. **L — Complete Account Creation**

Once you have selected your protocol, click **Done**. Thunderbird will begin to retrieve your folders and messages from your provider — a progress bar will be visible in the lower right of your screen. [Mozilla Support](https://support.mozilla.org/en-US/kb/automatic-account-configuration)

---

1. 1. 1. **O — POP3 Tip: Keep Messages on Server**

If using a POP3 incoming server, it's a good idea to select **Leave messages on the server** so a copy of retrieved messages is kept on the server and accessible from other email applications. [Microsoft Support](https://support.microsoft.com/en-us/topic/set-up-email-in-mozilla-thunderbird-8-0-f4726a9e-64d3-4494-9260-5762597fd1a6)

The qr code is correctly scanned by Google photo. It is the Thunderbird android app than simply do nothing apart activating camera video of phone. I try to make smaller or brighter the qr code on the desktop, nothing Import ally emails account is a nightmare.

Hello, this problem is driving me mad and I am at the point where I give up with Thunderbird

What's happening is "random" emails go into the outbox and stay there, I have no choice but to delete them.

There is no rhyme or reason for this.

The majority of emails send, even to the address that will randomly stay in outbox. !!

I have deleted the account and reinstalled it, used the same settings that are on another account that I don't have a problem with.

I am using android on galaxy tablet.

Anyone have any ideas

Thanks

I'm running Thunderbird at the desktop on various Linux and Windows boxes. These instances, along with other interfaces like RoundCube and the like can use my IMAP server to access all the folders in any given email account, move mails between them, add/remove/edit folders etc.

Thunderbird for Android can't even see them, not even the standard sent/trash/etc. options - only .INBOX. I have all the folders in my subscriptions file but nothing shows when I query the folder list from the client ("Manage Folders") and in any case I have unchecked "only list subscribed folders" in the settings for my account.

Any idea what I need to do to get at folders in this instance, because this setup is rendering the client semi-useless for me?

After the recent update, I have duplicated icons for K9. I exported my settings and reinstalled the app, then re-imported my settings. All my email accounts came back. However, only one works the rest fail authentication. I think I can fix that. However, the one account that does work, downloads every email 3 times. I have some email that have come down 6 times. How do I stop that. I have used K9 for years with no problems until now.

Dear all, good evening With Thunderbirb for Android is not possible to read this massage. All other email clients has no problem. I attached picture to see the problem.

Hi,

I really love thunderbird and want to move away from Outlook.

I am experiencing a delay in Push emails compared to my Outlook app. I am committed to get emails as soon as they are received by the server. For example I've observed recent emails 10min later in Thunderburd than Outlook to my Inbox.

I have my Inbox set to "Enable Push". Is there anything I can do to improve the speed of delivery vs Outlook? Both apps have same settings for Background data, and 'Allow background app usage'.

Any help would be greatly appreciated.

Thanks,

When trying to add my Outlook account, I am stuck at the authentication step. The webpage doesn't work. The screen recording I've attached is what happens on the second time and later; the first time it shows a different page (saying "The app named Thunderbird will be granted these permissions [... a list of permissions]; allow?" and I clicked "Allow") but it doesn't work either.

There is a "在 浏览器 浏览器中打开" option ("Open in browser browser" haha; it refers to Xiaomi system browser") but it opens a "Cannot find this page" error page. The "在 Edge 中运行" ("Run in Edge") button is unclickable.

Translation of the screen recording: Trying to log in to Thunderbird Android? Only continue if downloaded the app from trusted app store or website. [Cancel/Continue]

Hello,

after yahoo messed up their email beyond usability I am looking for an email client.

I like Thunderbird with it's neat and clean user interface. But even with 0 subject lines ans compact settings I only see 8 emails per screen on my 10" tablet.

Is there another setting that I have missed which would give me at least 20 emails per screen?

Also search is incredibly slow (one result every 1-3 seconds). Is that only because I just recently installed it?

Kind regards,

Gestern hat ALLES noch funktioniert und heute erscheint diese Fehlermeldung Ich habe keine Ahnung, was zu tun ist.

Ich hoffe, dass Ihr mir helfen könnt Dringende E-Mails warten auf Bearbeitung.

Tausend Dank für Eure Unterstützung

This is the 3rd day for me that https://forum.k9mail.app won't open/load. Has it been taken offline or what happened? Will it come back?

¡Hola a todos!

Llevo días intentando añadir una cuenta de outlook a la aplicación del móvil (en el ordenador, tras varios intentos, sí lo he conseguido).

Se trata de una cuenta personal y aunque ya he habilitado IMAP, no me da la opción de habilitar SMTP, que es lo que me está fallando.

El error que aparece es:

"El servidor devolvió el siguiente mensaje: Authentication unsucessful, SmtpClientAuthentication is disabled for the mailbox."

He probado también a cambiar el servidor por smtp.office365.com, pero tampoco lo consigo de esta forma. ¡Ah! y está con Oauth2 también.

Me tiene un poco desesperada el tema, así que toda ayuda es bienvenida.

¡Muchísimas gracias!

Saludos.
