Thunderbird for Android Community Forum

I was working with my own simple pop3 test server and noticed thunderbird also K-9 and even Gmail seem to send some unstandard commands to the server causing an error. FairEmail however works fine. The server is a simple pop3 for local testing can anybody explain why your email clients are not compatible with pop3 standards perhapse how you deviated from the standard?

I tried to connect to my personal outlook email account on a fresh installation of thunderbird mobile. The setup wizard gave the correct configuration as described in microsoft's official documentation. But the following error occured: Authentication unsuccessful, SmtpClientAuthentication is disabled for the Mailbox.

IMAP is enabled in microsoft's mail account settings on outlook.com.

Hi, I seem to be missing the send button in the Android app. (I do know that it's supposed to be the regtangular shape). When I compose a simple e-mail it is there. But when I want to reply a longer e-mail, it is missing sometimes. For now, I have found no pattern for when it is there and when it's not. I can't click on Alt or anything, since it's on a smart phone.

Hello, when I try to answer a message or forward an e-mail, both the attachment, send and more options buttons are missing. They are there when I compose a new e-mail. What can I do?

Just started to use Thunderbird mail app on Android smartphone but it doesn't seem to be showing badge count for new emails & seems to be delayed in receiving new emails.

Lorsque je sélectionne plusieurs messages dans la boîte de réception et que l’appuie ensuite sur la corbeille, il arrive souvent que les messages reste t dans la boîte de réception.

Seit dem Update über Playstore wurden alle Mails vom Posteingang (Gemeinsamer Psitereingang mit mehreren Konten) in den Papierkorb verschoben und die Einstrellungen für Mails Abfragen wurden ebenfalls verändert ! Wann ist mit einer Bereinigung zu rechnen? Ein manuelles Verschieben vom Papierkorb in den Pisteingang ist ebenfalls nicht möglich. Dieser Fehler ist sehr ärgerlich ! :-( MfG

I'm using Thunderbird on my Chromebook. I can't use the pointer to open the "more options" menu (the three dots) in the email to get to forward and other options. Hovering over the dots shows the "More Options" message, but clicking does not open the menu. I have a touch screen chromebook and discovered that I can touch the three buttons and it opens. Once the menu is opened, the mouse pointer works to select forward and the other options.

I am having a configuration problem on my Android phone, configure it from the application installed on my Windows laptop. I receive my emails but they are periodically completely deleted during message synchronization. how to resolve this malfunction? THANKS

On my Android phone, emails from my thunderbird account are no longer synching. I no longer get emails on the phone app. I currently have version 17 installed, and nothing happens when I tap on sync account. The only thing showing in the window is "Load up to 100 more". And nothing happens when I tap it. I'm lost and don't understand whats happening.

In Thunderbird for Android, Thunderbird does not notify a received email, when: I have created a setting with a rule/line, where this email is moved to a underlaying folder.

I cannot connect my gmail account to Thunderbird for Android (although no problem whatsoever in Thunderbird for Computer). It always fails when Thunderbird tries to connect the SMTP outgoing server. Then it says after a while NETWORK ERROR failed to connect to smtp.gmail.com .... I am using the standard IMAP configurations. Please help.

I am unable to send emails from android Thunderbird, I have something called a unified mailbox plus 2 that have my correct email address. When I send an email it sits in the outbox of the first one with my correct email address and won't send even after selecting send messages. Why do I have a unified mailbox plus 2 others? Thanks

I got these instructions from Charter.

How to set up Spectrum Email on third-party clients

Dear Spectrum customer,

Here's some helpful info you may find useful after our conversation.

You can easily set up Spectrum Email on your cell phone, laptop or other mobile devices.

To get started, make sure you have the following settings:

   Username: Your full Spectrum email address

   Password: Your Spectrum email password

   SSL: On

   Protocol: IMAP

   Incoming Server Port: 993

   Outgoing Server Port: 587

   Requires Authentication: Yes, or checked

You'll also need to enter your incoming email server and outgoing email server. The server that allows you to send mail is the outgoing or SMTP server. The server that lets you receive mail is referred to as an incoming, POP or Mail server. Those will vary based on your domain, which is the part of your email address that follows the @ symbol, such as charter.net.

The problem is with connection security. The only 3 choices you offer are none, start tls or ssl/tls If you add a choice of just ssl my roadrunner email will work just fine.

This is what senders see when they try to send me an email Subject: Mail System Error - Returned Mail with Subject: Test From: Mail Administrator <Postmaster@msg.pkvw.co.charter.net> Date: 4/7/2026, 10:36 AM To: ksmith29@carolina.rr.com This Message was undeliverable due to the following reason: Each of the following recipients was rejected by a remote mail server.
