Thunderbird for Android Community Forum

When composing emails in Thunderbird for Android, I can't find any options to format text.

I can't select a typeface (even the most basic html tags for serif/sans-serif/monospace aren't available) or even make text bold, italic or underlined.

This makes it very hard to create emphasis where necessary, and it feels like ancient emails from before HTML formatting.

Is there something I am missing, or does this depend on the phone?

NB: I can do this with my messaging apps and the Gmail app, which I prefer not to use.

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

Hi everyone, I’ve been using Thunderbird on Android for emails, and I’ve noticed that notifications sometimes get delayed when I’m gaming on my phone. During longer gaming sessions, emails don’t show up right away and only appear after I exit the game or switch apps.

I’m guessing it might be related to background app restrictions or battery optimization, but I’m not completely sure. I’ve also noticed something similar while playing heavier or modded versions of Stick War: Legacy (https://stickwarmods.com/), where the game tends to keep the phone more “locked into performance mode,” and background apps (like email clients) seem to get deprioritized. In those cases, notifications also feel delayed until I minimize or close the game, which makes me think it’s more about Android’s background process management during sustained gaming sessions rather than the email app itself.

Has anyone else experienced delayed notifications with Thunderbird Android while gaming? Any tips on keeping notifications timely without affecting game performance would be really helpful.

I recently set up Thunderbird on my android phone and managed to finally connect my iCloud email to both mobile and desktop (didn't realize i needed two different passwords for each).

After a few weeks of it working fine, I'm now being notified of some authentication issue for mobile. Does this mean I have to re-do the app specific password again? Will this be a consistent thing I would have to do for my iCloud? Don't need to do this for any other email I have set up through the mobile app.

Anyone know of a solution for this? I'd hate to continuously need to revoke and create a new password for just this email address.

I'm coming back to Thunderbird, from bluemail, and was wondering if you could add a feature they had. Essentially, you could tap on the profile icon in the inbox, and you'd get a screen with all the messages you had from that address. From there, you had a button at the bottom of the screen that would open a menu with options to: message, mark all read, and delete all. Theres a confirmation dialog after the delete all option is tapped.

Is this something you could add?

Ich habe die Version 22 installiert. Die Signatur hatte ich vor dem Update geschrieben u. eingefügt. Es hatte mir bisher immer die Sig in meinem Format eingefügt. Erst mit meiner kleinen Änderung ging das Format verloren, lässt sich nicht ändern. Egal in welcher Tastatur (gboard od. Samsung), wenn ich versuche einzufügen bzw zu ändern, es wird mir der Zeilenumbruch nur im Schreibmodus im Signaturtextfeld bei der Tastaur nur bei Änderungsversuch des Textes dort nicht mehr zur Verfügung gestellt.

OpenKeychain is a free and open-source Android app that implements the OpenPGP standard. It lets you manage cryptographic keys and use them to encrypt, decrypt, sign, and verify text, files, and messages so that only the intended recipients can read them and so that authenticity can be checked.

It is no longer actively developed for new features (maintenance mode with security fixes only), though a maintained hard fork called OpenKeyRing exists that continues development and adds features such as S/MIME support.

Hi, I’ve been using Thunderbird Desktop for years with S/MIME encryption. Since S/MIME is not currently supported in Thunderbird Mobile, I can’t use it on my mobile device.

Is S/MIME support planned for a future release?

Thanks.

Why if you save 2 drafts does the second save wipe out the first? Why is the spell checker used in Write so patchy and disjointed? Why is the select text- cut copy paste- so useless in amending mail?

Why does it somtimes eat emails - they just disapperar.? Why is the share function so limited - docx-

Until recently when using Thunderbird on my pc, android and Kindle fire HD when I start typing in a name in the TO field I see a list of possible email addresses. Still works on win11 pc, android phone but no longer on my kindle fire hd her 21.1

Something is wrong with Thunderbird. I have uninstalled and reinstalled many times. Unable to get inbox emails. Infact no emails are coming. You can see the processing circle working but never completes action. Not sure if I am doing something wrong or the app is the problem. Using Samsung tablet. All apps updated. Please help.
