Thunderbird for Android Community Forum

I'm using a Galaxy22 and have T/b for Android installed and ready to go. I've followed all the directions to import everything from my T/b on my desktop, which is the latest as I do automatic updates. But when I open T/b for Android, I see something called "unified inbox" with absolutely nothing in it, just a blank screen and a "compose message" icon on the bottom right. Where's my stuff? Please help! I can't handle Samsung email anymore, it won't send out any messages.

I have numerous Ionos email addresses. No problem seeing all received emails in Thunderbird app on my Windows PC. But Android app does not show some emails, despite synchronising numerous times. Problem is often with emails not showing in the unified inbox on the Android app. Also a problem with sent emails not showing. Today I looked for an email I had sent four days ago, and it was not in my Android sent folder. Synchronised, still not there. Synchronised again, still not there. Went online to Ionos and opened the sent email. Synchronised Android Thunderbird again and then it appeared. Why can't Anroid Thunderbird see certain emails? Problem seems to be especially bad with emails I have previously opened in Thunderbird on my Windows PC. Doing so seems to make the emails invisible to Android Thunderbird.

I have imported from my Windows desktop program to Thunderbird Android App using the QR code, but existing messages are not appearing, only new ones.

Can't scan QR code from desktop to import settings(mobile). Upon opening Thunderbird for Android I'm shown a window that asks 'Already using Thunderbird on Desktop?' My answer: Yes! There is also a blue button that states 'Import Settings' in the afore mentioned window. I click on the Import Settings button as I have the QR code displayed on my desktop monitor. The next thing I see on my Android (Pixel Pro 10XL) is basically just a picture taking screen where it states: 'Align the QR code provided from Thunderbird Desktop' My problem: there is nothing to line it up with. No little 90' ticks used to outline the corners of a square, nothing. It just looks the same as if I were using the camera app (no little ticks outlining corners of square). So in this case there is nothing in which to line up.! I'm using Thunderbird 151.0 on my desktop and have successfully used the QR scanning on my phone in the past. I can't bypass this window as this is my first time using the app on my phone. Am I doing something stupidly wrong? Any help to resolve this problem would be awesome! Thanks *** as I eluded to earlier, I can't get into Thunderbird on my phone so I don't have the version. So I'll just reiterate my desktop version to fill out this form.

How can I synch my address book on my laptop with a Moto G 2025 phone? I need the required steps to do this plainly spelled out, as I am not a super computer user. 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.

Notice the h it puts in after my rr email address Thank you, Kevin

Thunderbird for Android: When sending a message, the copy moved to the Sent folder is not marked as "read" after moving. Messages sent from the Android client and subsequently auto-filed into "Sent" or "Sent Mail" are still marked as "unread" after the move. They should be marked as "read" as part of the move, just like with the Windows client. I've searched the various Settings and I can't find any related setting.

Thank you for your attention to this matter,

With my Pixel 9a, I installed TB Android mobile. The settings were imported into the phone from my desktop and I went through setup. However, when I tried to sign in I receive an error, Oauth sign in failed. Oauth is currently not supported with this provider. Retry does not work. I use Yahoo Mail on my desktop. My Server is: pop.mail.yahoo.com Security SSL/TLS Port 995 Oauth 2.0 my user name @yahoo.ca These are the settings on my desktop as well. None Next step is to sign in and then I get the error. I tried IMAP, same. Under Oauth 2 there a pull down menu with: Normal password, Encrypted password or Client certificate. I'm not sure what these options are. I tried IMAP and got the same error. I'm hoping that someone can advise me as to how I get past this Oauth 2.0 error and finish installing Thunderbird for Android. Thank you

When I launch Thunderbird after downloading an update I get a message that says 'the installation seems to be incomplete. Check your hardware (what hardware?) and disk set up and/or reinstall. How do I check hardware and disk? If i reinstall will I lose my old messages?

I wish thunderbird/firefox would stop behaving as if everyone knows how to repair these things. I still haven't managed to stop thunderbird from asking for and often rejecting my email password, despite two kind people trying to sort it out.

From what I can see online, the instructions are, read the QR code and everything works. I've also seen a lot of wondering about QR codes not working. I get QR codes, but Thunderbird can't read them. Seems to be a bug in the QR format.

Hi My local folders disapear, and I got an sugestionfrom Toad-hall, that i followed: Renaming the folder names to shorter names and download from the oficial Thunderbird download. When i removed thunderbird and install agin it works by magic, but each time i close Thunderbird and open it again my local folders are diapeared Kind regards Ole Storm Mikkelsen
