Thunderbird for Android Community Forum

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.

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

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.

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?

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

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

Transfer from Thunderbire on PC Win 11 to Android version Xiaomi17 smartphone

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.
