Thunderbird for Android Community Forum

I am using a Samsung S22 android and Thunderbird 20.1. My email server is Xfinity (comcast.net) and set on imap: smtp.comcast.net; SSL/TLS; port 465; auth: normal password

When outgoing emails are somewhat large, or sometimes for no reason at all, the outgoing emails get stuck in the OUTBOX. No amount of clicking on "Send messages" works, nor does sending them to DRAFTS and re-sending them. They again get stuck in the outbox. I have changed the port #s to no avail. My desktop Thunderbird HAS NO OUTBOX !! Why is that? Consequently, no emails get stuck, no matter how large or small. I've tried everything and searched everywhere.... no help.

Hello Thunderbird team,

First of all, thank you for the great work on Thunderbird for Android. I've been following the community discussions and noticed that many users are reporting recurring issues related to email syncing, notifications, account setup, search functionality, and overall app performance.

As a suggestion, it might be worthwhile to collaborate with experienced mobile app development companies such as AppVerticals. Their expertise in Android application development and user experience could help enhance performance, improve stability, and address some of the common issues users are facing.

I'm not affiliated with AppVerticals—I simply believe that bringing in additional expertise or consulting with companies that specialise in mobile app development could benefit the Thunderbird Android project and improve the experience for the growing user base.

What do other community members think? Would collaboration with external mobile development experts be something worth considering?

Thank you for your time, and I look forward to hearing everyone's thoughts.

If you'd like, I can also Make it sound more community-driven, technical, or feature-request focused.

Ich habe die thunderbird App auf meinem Smartphone installiert. Problem: die Nachrichten werden nicht im Appsymbol angezeigt obwohl es überall angeschaltet ist. Problem 2: Wie bekomme ich 15min Emails abrufen auf permanent umgestellt?

As of recently I can not use the "Empty Spam" or "Empty Trash" options I have to literally select all items in the trash it junk/spam folder and hit the trash button.

Any suggestions?

I'm using thunderbird android with a Gmail account. Using search only yields results from the past weeks. Triggering a server side search yields nothing. If I execute the same search on Gmail I get many results. Is it a config issue or a bug?

Thunderbird has stopped receiving emails. I followed the instructions I found. restet cache, I have enough memory, hosting service account space is adequate, checked login credentials (I have been sending and receiving for months with no problems) restarted phone. I am getting no error messages.

This happened with my last email program and I installed Thunderbird after no one could find a problem.

Hello everyone,

Summary: I am trying to set up my gmail account on my new phone, but after (what appears to be) successfully logging in, the Thunderbird for Android application does not pull me back out of gmail. Instead, I remain logged in to my gmail account as if in a browser. As you can see from my photos, it takes me to the point where I am truly into my gmail inbox, but I am checking it as if in some sort of outdated browser and not as if in Thunderbird. I am stuck; sitting in my gmail account, logged in; able to view email, check and change account settings, even get onto other parts of my google account. Unfortunately, I cannot find a way to get back out of my gmail account that returns me to the Thunderbird for Android accounts setup process with a successfully login to gmail. I end up having to hit exit or to close the app, which causes the account setup to fail.

Expected Behavior: Open the Thunderbird for Android App. Setup new account (gmail which produces an automatically detected OAuth 2.0 method). Give login credentials, gain access to gmail, and then be auto-redirected back to accounts setup process in Thunderbird for Android with full IMAP + SMTP access to my gmail.

Problematic Behavior: Same as above, except I am stuck as if in browser mode. When I exit and thus am returned back to the accounts setup page, I receive a failed notice (see photo). Immediately afterward, I tried to setup an account for the same gmail address on an old android phone and successfully logged in as expected. How do I get back to the main accounts dialog with a success?

Notes: The new phone is a linux-based phone (Furilabs FLX1s) on which I have found Android apps to function without hiccup. It seems like In fact, the Thunderbird for Android app itself seems to function fine. It doesn't crash. It allows me to navigate through the app menus flawlessly.

Thanks for the help!

Pixel 8a, 256GB/120GB free, Android 16, Thunderbird v16.1 Thunderbird stopped sending and receiving emails after several months. My storage is not full. I also deleted messages to be sure. I checked my android settings as indictated in the troubleshooting guides and have been unable to resolve problem. I have it set to automatically download emails. Manually checking emails by using the "refresh" button does not work either.

Obwohl ich schon mehrere Konten die ich auf meinem PC in Thunderbird angelegt habe per QR Code auf mein Android Gerät exportiert habe, erkennt Thunderbird Mobile nun den Code nicht mehr nachdem ich ein neues Konto hinzugefügt habe. Das Konto funktioniert auf dem PC perfekt, lässt sich auf dem Android Gerät aber auch nicht manuell hinzufügen

All the requested QRs are generated but when I frame them with the smartphone camera they are not read and therefore the procedure is not completed. If instead of the camera I use a normal scanner, in this case it reads all the details of the QR. Can you tell me the cause and remedies, Thank you very much. Paolo

Thunderbird for Android: Microsoft365 Outgoing SMTP auto-filled settings are incorrect and there does not appear to be a way to change them. The "edit configuration" only has a Incoming IMAP configuration screen, not an Outgoing setting screen.

The setting should be SMTP.Office365.com but it configures it as SMTP-mail.outlook.com. It allows editing of Incoming Settings but there is no screen for Outgoing server changes?

It works fine in Thunderbird for Windows with the correct settings stated above.

Hello Guys; Since ages I use Mozilla email product (started with Navigator...). And I only use POP3 accounts so I've a lot of emails stored on my computer. Fine. I've imported my settings into Thunderbird for Android with success but this leave the data behind. How could I store my email folder on my phone and where to put it ? Many thanks in advance for your help and have a nice and bright day.

I exported my settings from desktop thunderbird when setting up Thunderbird Android 20 but discovered it was automatically marking messages as read. That makes it difficult to have a peek at messages when I'm out (in case there's something urgent) but still see those messages as unread when I return to the desktop.

https://support.mozilla.org/en-US/questions/1504592 claims to have found the option to do that, but it's an old message that has been archived without ever saying where that option was found. I've tried settings search as well as a visual search of all settings without seeing a relevant option.

Does that option actually exist? Or do I have to go back to K9 (which, at least in v19, had that option)?

Android 13 Tablet

I have TB for Android set up and working. This is a lw end tab for my needs away from home.

I have set up mail identities as well as signatures fo r3 accounts I am working with for personal, hobby, and business. So far it is working fine.

However, today I attempted to add a second identity to one of the Gmail accounts which TB on my Windows 11 system allows, but on the Android version it is not allowing a 2nd identity on any of the accounts.

Is this a bug or something reserved for the premium, version. There is no pop up or other indication telling me otherwise. The "Save" icon is just grayed out. I also scanned this forum and was not immediately able to get anything on this item.

Thanks
