Thunderbird for Android Community Forum

I recently installed the Thunderbird app on my Samsung S25. I use two email providers - hotmail.com and comcast.net. Thunderbird gives incoming email notifications for my hotmail address but not for comcast.

One of the posts I saw said to make sure the app runs in the background and there are no battery restrictions. Mine was already running in the background and I removed battery restrictions. That did not solve the problem.

I want to move email messages around in local folders, but "move" doesn't show even when enabled in settings when the account is POP3

However when using IMAP it is worse as the App keeps messing not only with the server messages an folders, but also with other devices.

Sometimes I got a problem with Gmail where I get the error "Too many simultaneous connections", both desktop and Android. I found that Gmail servers support 15 connections. I could reduce the number of connections for desktop in the config editor, but I would like how to do that in the Android app. Some times it creates a lot of connections, and I think the numbers stack up together with dead connection when I reboot my router and get a new IP, so I'm wondering how to set to get just one or two simultaneous connections on Android.

I activated message synchronisation for 15 min. intervall. The first few syncs were working correctly (around 3), then I'm just able to sync manually. In the thunderbird app settings, I already activated the battery setting to not restricted (I'm using my phone in german, not sure if the translation is 100%). Before that, I was not even getting the first syncs. How is it possible to sync reliable in the set intervall?

Hello,

For a few days everything worked perfectly. Now suddenly I cannot fetch any emails on neither Thunderbird for android nor Thunderbird on Ubuntu. Both latest versions at time of writing. Sending mails works. Another email client works, another email address from the same server (but different domain) does work.

Any ideas what I can do?

I am experiencing a problem with Thunderbird for Android.

My setup:

• Smartphone: Samsung Galaxy S23 Ultra (SM-S918B)
• Android version: Android 16
• Computer: Windows PC
• Desktop email client: Thunderbird for Windows (latest version)
• Email accounts are configured and working correctly on the Windows version of Thunderbird.

The issue concerns the Android application. Despite using the same email address, login credentials and server settings that work correctly on my Windows computer, I am unable to properly configure or synchronize the account in Thunderbird for Android.

The desktop version connects without any issues, while the Android application either rejects the settings or fails to synchronize properly.

I have already:

• verified the email address and password,
• confirmed that the same credentials work on the Windows version,
• checked the incoming and outgoing server settings,
• reinstalled the Android application,
• ensured that the device has an active internet connection.

Could you please advise what additional steps I should take to resolve the issue?

Thank you in advance for your assistance.

Kind regards,

With three accounts, if the first account is set to folder poll frequency = 15min and the others are set to never, the first account does not poll its folders after 15 minutes. The bug workaround is to set all three accounts to 15 minutes. However not knowing this caused me to miss important emails.

When manually refreshing an account, new messages do not appear automatically; you must scroll down to see them.

This is a regression from a previous fix in a version of K9 from a few years ago I believe.

Mail.com support recommended that I install Thunderbird to clean out my inbox. Things went perfectly and I managed to delete 20,000. Then the app just STOPPED. It wouldn't delete any more. I emptied my email's trash, restarted my phone twice, and cleared the cache several times. The app is just inoperable.

Please help! I have 265,000 more emails to delete.

There are two pdf files attached to an email I received. When selecting view all and then save all, one file gets saved with the name of the other file, and a zero byte file is created with correct name. The other file is not saved. This erroneous behaviour is repeatable.

Hi all,

Is there a way to export/backup all the emails and folders from an account using Thunderbird for Android? I've searched around and can't find any sign of it, or mention here on support.mozilla.org or elsewhere on the web, so I presume that the feature doesn't exist, however I thought I'd ask here just in case.

My use case is that I've got an old email account which I want to backup before I migrate away from it.

Cheers :)

Hello,

I know how i can add an image or a banner in an email in the desktop version, i also know how i can make a sort of banner with a signature file in the desktop version.

But i would really like to know how i can use a email banner or image and center it in the middle of the top of the email when i use the android app. is that possible? And which steps do i need to take?

Thank you

I'm using Thunderbird for Android 19.2 from Google Play on Android 16.

When I try and send large-ish (around 1MB) messages they are not sent, and a notification "Failed to send some messages / Unable to Send message" appears.

This isn't a server restriction. The mail server it's connecting to is mine, and with a smaller message log entry "postfix/smtps/smtpd" appears. With larger messages no SMTP connection is attempted and no such message occurs.

How do I configure the size at which this occurs?

I am preparing to migrate from K9 mail to Thunderbird for Android. Before I go through the process and learning curve for the software, one key feature will be the determining factor.

Does Thunderbird for Android have inbox rules, possibly also called Filters like in Thunderbird Desktop, that will automatically find keywords or sender info in the header of a received message and deposit that message into a designated alternate folder?

That would determine whether I switch to Thunderbird for Android.

Thanks.

I'm using a Galaxy22 and have T/b for Android installed and ready to go. I've followed all the directions to import everything from my T/b on my desktop, which is the latest as I do automatic updates. But when I open T/b for Android, I see something called "unified inbox" with absolutely nothing in it, just a blank screen and a "compose message" icon on the bottom right. Where's my stuff? Please help! I can't handle Samsung email anymore, it won't send out any messages.
