Thunderbird for Android Community Forum

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've switched from K-9 to Thunderbird for Android.

One difference I've noticed is that the message notifications remain in the launcher even after I've deleted those messages in Thunderbird. Thus, I have to handle messages twice.

Is there a setting to make notifications go away when the underlying messages have been deleted?

Thanks

I used clone phone to transfer from a Samsung Galaxy S20 to a oneplus 15 and Thunderbird android did not transfer. How do I get it working and access my old emails?

Hi All,

I have a Galaxy S22 running android 16 and have been getting the standard email notifications for each of my inboxes.

Recently I get a duplicate notification appear for a new email almost immediately after I clear the notifications screen or swipe it away.

I was hoping an update would solve the issue but I updated it once since it began but the issue remains. I have done all the basic troubleshooting steps like cleared cache, stopped app, restarted device etc. but nothing seems to work.

I havent uninstalled the app yet because I didnt want to risk losing anything important, but if thats the next logical step aside from a configuration change I will do it as these notifications are becoming rather annoying. Help please!

The Delete button (I've just begun using Thunderbird for Android) sends email to Delete-land: gone for good. There is no way to reprogram it to send to Trash. One can, alternatively, hide it on the main screen by setting swipes left and right to None. But it is still there in the Read screen....and potentially dangerous. If you try to set a swipe to Trash rather than Delete, there is no Trash option. So you have to set it to Move and choose Trash each time. This reduces the utility of Tbird Android and means you have to be extra-careful when reading emails.

Also, no way to reduce image sizes (by percentage) when attaching large picture files...unless you reduce them in advance in an image processing program.

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.

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.
