Hi All, I have been sending emails through Android Thunderbird, but they aren't being synced to the server, so I can't see them anywhere else. I've set the Sent folder to sync (as well as the Inbox). Pressing the sync button just spins the indicator, but doesn't actually sync. When I try to move or copy messages, an error comes up saying that messages can't be copied or moved that aren't synconised. How can all my messages (sent, inbox, everything) be synced so that I can see them everywhere? I've just turned on sync debugging, will see the results soon.

In V.10, it used to be I had to really swipe all the way left for delete to occur.

Now in V.13 only a small/partial movement deletes.

This is tool easy to mis-trigger. Please go back.

Thanks

Hi all,

I have tried on K9, and Thunderbird Mobile.

On my tablet, with K9 mail, I exported my fully working accounts, and imported to my phone. All worked, except one account, where it only has an outbox. No inbox, no sent folder, nothing.

I then Installed Thunderbird mobile, and used the QR code link in the desktop app, to sync to it. Same issue. All other accounts work fine, but not that one account. Only an outbox.

I've logged into the web version of that account, and no restrictions are on folders. And it's only on my phone. On tablet it's fine.

I can't even choose folders in settings, for sent, etc, as there are none to choose.

Any help would be greatly appreciated. Thank you

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

Hi. For a long time, I've noticed that emails I send from home are sent, but those I try to send with the same settings do not get sent when connected to the Internet in 4 out of 4 cafes. My ISP, Zen, hasn't been able to explain why. I've tested whether Google VPN blocks it somehow, and it doesn't. I normally use Thunderbird. Today, I found that, in the same cafe, messages I tried to send using Thunderbird failed to send, whereas there was no problem with GMail, Proton Mail or Outlook. Any suggestions?

Hi,

I'm looking to make Gmail my principal email account, instead of using my ISP account. Gmail requires 0Auth2 authentication, as many will know.

I'm a Luddite and prefer to use POP3, for a number of reasons. Thunderbird works fine (with POP3 Gmail), on my computer. Unfortunately, 0Auth2 doesn't appear as an authentication option, for POP3, in Tbird for Android. So the TB android app forces IMAP on my tablet and phone.

Is there any way around this? Are there any plans to incorporate 0Auth2 authentication for POP3 within Tbird for Android?

Thanks

I use the same e-mail address on my desktop and my Samsung android phone. I was told to change my desktop e-mail from POP3 to IMAP which I did and then told by the Thunderbird desktop forum to change also my phone settings from POP3 to IMAP. I was told in order to do that I needed to create a new account first and then delete the old account.

However, when I go into server settings and I put in my e-mail address from my desktop, it states "e-mail address already in use". Clearly I do not want to create a new e-mail address - just use the same e-mail address that is on my desktop so that I can access e-mails on my phone that appear on my desktop. Help please!

I cannot close the Thunderbird email app on Samsung Galaxy S25 Ultra Android 16 One UI 8.0. The back arrow in the navigation bar no long closes the app windows. Have to use the back to home center button. Is there a solution to this problem?

I have a POP3 account setup on my laptop and recently downloaded the thunderbird mobile app for android on my phone. I setup the android mobile app as IMAP to access the same server account as my POP3 laptop. When I look at my thunderbird phone email notifications in the morning, I compare them to the emails in my inbox on my laptop and find that the emails I see on my phone DO NOT show up in my inbox on my laptop ? I thought IMAP was NOT supposed to delete messages on the server when retrieved to my phone. My intent was to just read emails remotely on my phone but leave them on the server. I want my POP3 laptop account to see all of my emails and control whether to delete them or not after reading.

I just installed Thunderbird 12.0 on my Phone (Galaxy Note20, Android 13). Account setting were taken from my Desktop PC using the QR Code. In all three Accounts only Mails in the Main IMAP-Inbox are shown. Subfolders (like "sent" or "drafts") are all found, but the messages inside will not be shown. It will only say "Load more messages" but does not find any. In K9-Maiil 11.1 this still worked, but I had to uninstall it as after the automatic update to 12.0 it suddenly kept crashing on startup.

Already tried to add my main account from scratch on my tablet (with a fresh install of Thunderbird 12.0), but the problem with empty subfolders remains.

Any thoughts on this?

Ich habe Thunderbird als Standard-App für E-Mail eingestellt und Gmail dafür abgewählt. Doch wenn ich einen E-Mail-Link klicke, sprich tippe, gibt es entweder gar keine Reaktion oder Gmail will den Link öffnen. "Rechtsklick", sprich langes Tippen funktioniert. --

I have toggled thunderbird as standard and gmail off. But either there is no reaction at all, if I click an email link, or gmail wants to open it.

I just installed Thunderbird for Android on my Pixel phone for the first time. I have used Thunderbird on my desktop PC for many years, so I am very familiar with Thunderbird in general. I used the "Export for Mobile" feature on my desktop installation, to import my account settings into the Android installation.

For the most part, Thunderbird for Android works great, as I would have expected. However I am seeing a problem which appears (to me) to be a bug. When I compose and send an email on my phone, and then look in the "Sent" folder on the phone, the email that I just sent shows up there. But only on the phone. If I open Thunderbird on my desktop PC and look at the Sent folder there, the email that I sent from the phone is not there. Apparently, it only gets placed in the phone's Sent folder, but it does not get copied to the email server.

A few other details: -- I use Thunderbird on 2 different desktop systems, a PC and a Mac. When I send email from either of those, that email DOES show up in the Sent folder on the other system. Emails that are sent from either desktop system also show up in my phone's Sent folder. So I know that the Thunderbird desktop application does upload the message to the email server's Sent folder correctly. But Thunderbird for Android does not upload its sent emails.

-- I don't know if it matters, but my email server is Microsoft 365, hosted by GoDaddy.

-- As far as I can tell, the most obvious setting for this is the "Upload sent messages" checkbox, which can be found in the "Sending mail" section of "Account settings" in the Thunderbird Android settings. This checkbox IS IN FACT turned on. I could not find any other settings which could possibly affect the copying of sent messages up to the email server's folders.

Is this a bug? Any ideas what might be causing this? Thanks for any help.

I am on Android 16 on a Samsung phone. My messaging server is a POP. I have enabled the synchronisation on the inbox. I have set the period of synchronisation to 15 min I have enabled the notifications on the inbox. I have enabled the notifications of new message on the account I have enabled the notification of Thunderbird on Android

but it is not working !

I donated and installed thunderbird on my laptop last week. I have donated twice more in the last few days to install thunderbird on my android phone in the last few days unsuccessfully. I do not know what I am doing wrong. Can you help me?

Hi, I use TB for quite a while on my pc. Tried to use TB 4 A. I used the import function. Got 3 accts. Scanned the QR code and it seemed to import all of them. But then I noticed the Gmail POP acct was not showing any entries. I got confused, so I uninstalled and then Only imported the Gmail account. Nothing was there in any folder.

Is there a problem with POP? The documentation says no.

Thanks, Sam

Hi All,

I am installing Thunderbird from official GitHub releases and I am wondering why I am getting info from Obtainium that thunderbird-14.0 is something called "pseudo-release".

Can someone explain me this term regarding GitHub apk files? Is it OK to install it?
