Thunderbird for Android Community Forum

Hi, When my inboxes are unified I see notifications get delay, and When I turned them back to individual inbox view I see notifications delivered at standard interval..

I'm on Android, simply configured Gmail and outlook for Thunderbird.. Sometimes i get delayed notifications - don't know why ??

Sometimes say Microsoft incoming server fetched failed - like that similar it says...

How can I get the notifications at right time.. What would be the settings i should make..

Lately I found that each folder should be configured like [sync to be off] [push to be enable].. I've done that... What else in that menu we should make on/off . [attached screenshot]

I just thiught to have email notification delivered on right time.

Within my Outlook.com email account i have an archive folder with 36 sub folders.

In the Thunderbird app for Android only 2 of these sub folders are visible.

I cannot find any setting that to resolve this issue

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 use a mail forwarding service, Fastmail, used to be Pobox. The entire body of the message is visible in fastmail, if I log in directly to fastmail. I have my fastmail account set to forward messages to a Gmail account, which is linked to my mobile Thunderbird app.

The message header appears in that Thunderbird Inbox, but the body is empty.

I have checked the message size limits in fastmail, gmail, and the Thunderbird app. They are all at least 10Mb.

The particular message is only 3.7 Mb total according to details on fastmail. Also not forwarding as attachment

Where is the message body?

Thank you for any suggestions.

Thunderbird for Android (unlike the standard Android Email) still does not offer the ability to shrink a photo before sending it. The workaround is so clunky, having to use an Android photo editor to shrink images one by one, especially if one wants to send multiple photos, saving each one and then going back to Thunderbird to send the smaller images. Any idea where this feature is in the development list?

When I try to forward an email with an attachment on mobile I get an error that's not fully visible saying "Some attachments could not be forwarded because they have not be...' (I tried rotating the screen to see if it expands but it's the same unfortunately). It works fine on the desktop app, and it also works fine if I manually download the attachment and then draft an email and attach it.

Does anyone know if this is common, or how I can bypass it? I tried but couldn't find any info on this behavior.

Thanks!

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?

I'm using Thunderbird android app for the first time, and configured my mailbox.org account. Incoming mail appears just fine. I've confirmed my outgoing server settings and I get the message 'Outgoing server settings verified'. But when I try to send a message it just stays in my Outbox. I've tried tapping 'Send message' on the Outbox screen but nothing happens. Any ideas?

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.

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!
