Thunderbird for Android Community Forum

I am not getting ThunderBird for Android to work on my PIXEL 9 android phone. Version 21.0 Nothing has loaded for a few months. Not sure what is wrong but I do know Telus uses Google Mail Services and it is a pain inthe ass to logon without their interference. Might have to resort to setting up my account under Gmail but I do not want to. Frustrated Robert

Whereas on the Thunderbird Desktop software, where each identity on an account can have their own outgoing SMTP server, the Thunderbird for Android app does not have this feature. Why?

I used the "Export to Mobile" feature and got stuck for quite while until i found this out. This help article also only mentions this as a fact, but no explanation or anything. Why is there such a feature discrepancy between these versions? Why is there no warning while exporting that this will be an issue? Will this feature ever be added?

In my Thunderbird client on my tablet (Android), phone (Android), and laptop (Windows 11) over the last week, it has stopped emptying the Trash folder by clicking "Empty". Also, across these platforms the Trash folder will no remain synced, while it appears other system folders remain synced.

As I have not made any client setting changes (prior to troubleshooting this issue), I must assume a recent background change/app update has occured.

Please advise.

This is observed on Pixel 9 Pro. Running Thunderbird v21 from F-Droid.

Not sure if this is in the latest update, but if I select a message, the top of the screen (where we are notifications and battery level) turns into a black bar. This happens in, both, the unified mailbox and a specific mailbox.

Is this a bug or normal behaviour?

Mail notifications remains on the home screen and need to be removed manually. I had expected them to be removed after reading the mail or marking it as read. A notification summary with the number of received mails instead of a notification for each mail, as an option, would have been nice. /Sten

Hello,

I would like to report what appears to be a bug in Thunderbird for Android.

I use a POP3 account with the following settings:

POP3 Port 995 SSL/TLS

The same account works correctly in Thunderbird for Windows.

The problem only occurs in Thunderbird for Android.

What happens:

New emails arrive and are initially displayed in Thunderbird for Android. After the next synchronization, some messages disappear from the Inbox. The messages are not deleted from the server because they are still visible in Thunderbird for Windows. I also tested the same POP3 account in Samsung Email on the same Android phone. Samsung Email continues to show the messages correctly while Thunderbird for Android no longer shows them.

Troubleshooting already performed:

Reinstalled Thunderbird for Android. Removed and added the account again. Tested on both my Android phone and Android tablet. The same problem occurs on both devices.

Is this a known issue with POP3 accounts, or is there another setting I should check?

Thank you very much for your help.

Best regards, Diana

It is very painful to move each email message at a time to another folder. There is a requirement for selecting multiple messages and moving them to a folder. Want to know if this feature is available and if not would like to request it.

I realize that I can select all the messages in either the trash or the spam folder and then delete them, but the empty trash button does not work in version 21.0. it worked perfectly in the prior versions.

Hello,

I am trying to set up my email account on Thunderbird for Android, but the incoming server configuration fails during the validation step.Error Message Received:"Checking incoming server settings failed.

Authentication error. The server returned the following message: User is authenticated but not connected."

My Environment & Setup Details: App Version: Thunderbird 21.0 OS: Moto Edge 50 Neo, Android 16 Email Provider: Outlook.com Server: outlook.office365.com Protocol: IMAP Authentication Method: OAuth2.0

I have tried so far: Toggled between Wi-Fi and mobile data to rule out local network issues. Verified that my login credentials work perfectly via the webmail browser interface. Completely deleted the account attempt and retried the automatic setup process from scratch.

I have attached a screenshot of the exact error screen for reference. Any guidance on how to fix this authentication loop would be greatly appreciated.

This issue has been persistent for many months now.

If any more info is needed, please feel free to reach out. Thank You

When moving emails to folders, it is very difficult to find a folder in a long list of folders. Is there a way to mark frequently used folders as favorites so they appear at the top of the folder list?

Bonjour à tous,

I recently updated Tbird Mobile to v21.0. I'm on the latest version of Android released for the Samsung Galaxy Z Flip 6. The "Empty Trash" and "Empty Spam" commands no longer work. I have to go to the desktop version, empty those folders there, then go back to the mobile version and resync in those two folders to get the trashed files to "go away". This never happened before the v21.0 update.

Is there something I need to do/change, or is this a bug?

Merci d'avance, John

The options for my folders are all generic

I am using a Gmail account

I have folders

Specific folders

They only option Thunderbird is giving me is none

My email provider sometimes fails to send mail, so I find the mail that didn't send in the sending box (发件箱; I don't know the name in English), use the "edit as new mail" option in the mail 3-dot menu (there's a pencil icon on the top of the screen, but it has no reaction) and tap send button again. I find that every time I do this, the mail's sender identity is reset to the default identity.

I know my Thunderbird version is not latest and is beta, but I'm hesitant about updating. Is it a bug or designed behavior?

Steps to reproduce: 1. Turn off your device's network. 2. Compose and send a mail with an identity that's not the default. 3. Find the mail in the sending box, and choose "edit as new mail". 4. Hit send button. 5. View mail in sending box, it now uses the default identity.

Running version 21.0 on Android 17.

Emptied my trash just this morning. Worked fine. Went to do it tonight, said yes to the confirmation and it just sat there. No deletion. Sent a test message from another acct and that arrived fine, so it's not having problems accessing my server via IMAP.

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?

Running release 21.0
