Hi. I use Thunderbird Android 17.0 on my phone and tablet. Everything is great on the phone.

On the tablet, unified inbox worked fine until two days ago. Now, no email goes into the unified inbox and I have to open accounts individually to see email. The unified inbox still shows, but the last email in there is from two days ago. I did not change any settings and berichten that the checkbox is checked to show the unify inbox.

What cohort have caused this and how can I fix it?

I have installed Thunderbird on my Samsung phone and synced it with the desktop. All three of my gmail accounts came up okay, but when I go into them I do not get the inbox, only outbox. When I click on each account to try to sign in I get an error that says "OAuth 2.0 is currently not supported with the provider". How can I sign in to my gmail accounts on my phone in Thunderbird?1

Hi,

How do I transfer emails from Thunderbird Desktop to Thunderbird Android?

I have successfully imported my settings, but I want to add all my emails that are currently on my desktop.

How do I do it please?

Hi team. Recently, I downloaded the app, but I noticed that the incoming emails are updated every 15 minutes. Could you please reduce the time into 1 min? Also is there any notification for incoming emails? I made folders for better correspondence with clients. Still there is no notification for incoming email.

My K-9 in Android suddenly stopped to work a couple of days ago. The server asks for autentification. I haven't changed anything. I've uninstalled and reistalled the app and restarted my phone a Samsung S22 ultra several times. The app is recognating some settings automatically but it doesn't accept my old password with 16 letters in a group of four with highfens in between. What shall I do, please? Something wrong with the server? The version of the app is 17.0 updated March 16th 2026.

I exported all my 5 email accounts from Desktop Thunderbird to mobile Thunderbird. All were successful except for two accounts which only have one folder visible, the Outbox. All accounts are sycnhed and Manage Folders displays no folders. Help please to resolve problem.

Hello, I can't find a way to connect my contact database to Thunderbird for Android. How can I set this up so that email addresses can be easily added or imported automatically in the entry fields of a new email? Thanks in advance! Regards

I am not receiving emails on my phone. I have had to change my password on my laptop but don't know how to do that on my phone. It would be very helpful if you could tell me how to do it. Thank you. Nick

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

I installed thunderbird on my new Samsung A26. I tried to configure the imap connection for my email - provider is liwest.at - per their settings. the incoming mail check worked. but the outgoing mail check gives back the error "unable to parse tls packet header" I checked username and password multiple times and tried all versions of password authentication possibilities.

I googled the error but the only thing I could find was a possible mismatch in tls versions. I asked my provider about it - their customer service could not confirm with their technicians what version is in use but according to their documentation it should be tls 1.2

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 have my settings to confirm deletion in message view, but not from notifications. I've had to re-set them several times over the past month or so because it keeps changing back to confirm deletion from notifications. I think it's happening when I need to restart my phone, but it does it at random too. How do I fix that?

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!
