Thunderbird for Android Community Forum

Hey there. Hope you're all doing just fine.

TL;DR Tried moving all my email messages from GMail to Infomaniak. Worked fine because I can see all my old GMail messages now on my Infomaniak Inbox using Thunderbird on my PC. But my phone refuses to show me the latest messages. It only shows me messages from 2025. --- Now with a lot more detail. I use Thunderbird as my email client of choice on both my Android phone and on my Linux (Manjaro) PC. TB on the PC is running 140.8.1esr 64 bit flatpak installed. TB on my phone reads 16.1 and has been installed from the github repository using Obtainium. I use IMAP for receiving and SMTP for sending. No POP3.

I have two email accounts. One at GMail and another at Infomaniak. Up until recently, I've only had the GMail account set up on both my phone and PC. I've been using Infomaniak as webmail just for testing. But recently I've decided to add Infomaniak's to both my Thunderbirds and move all my emails from GMail to Infomaniak. I used Google Takeout to download the mbox files (inbox, archive and sent), then using my PC I loaded the mbox files in my "Local Files" and finally I moved the messages to my Infomaniak correct IMAP folders.

It all looks just fine in my Linux PC. But on my phone I can only see messages from 2025 on my inbox. And I have many messages from 2026. I can see them using TB on my PC, or via the webmail. They just won't show on my phone.

EDIT: It only shows me messages from 2025 and prior to that. But it doesn't show me all messages from 2025. Many messages from 2025 are also missing. And from previous years too. This is not happening on the inbox folder only. It is also happening on all the other folders too. It's as if TB was filtering the messages. It's driving me nuts.

I've already tried clearing TB's data and import my settings. Still only have messages from 2025. What could be going on with Tbird on my phone?? Thanks in advance. Cheers

Hi,

I really love thunderbird and want to move away from Outlook.

I am experiencing a delay in Push emails compared to my Outlook app. I am committed to get emails as soon as they are received by the server. For example I've observed recent emails 10min later in Thunderburd than Outlook to my Inbox.

I have my Inbox set to "Enable Push". Is there anything I can do to improve the speed of delivery vs Outlook? Both apps have same settings for Background data, and 'Allow background app usage'.

Any help would be greatly appreciated.

Thanks,

How to add custom filters in Thunderbird for Android. In the desktop version, I can add custom filters for each account. This is not possible in the Android version. How can I solve this problem?

Hello I used to have an alias email from mailbox.org set up in Thunderbird and it operated just like a normal email however this seems to not be working now and I'm wondering if anybody knows how to maket this happen it was so useful.

Sorry I don't know how to find out which Thunderbird version I am using

This issue is both for desktop and Android.

I'm blocked by cbl.mailcore.net, so I can't receive my mail. I've contacted spamhause but I still can't get the thing to work. So have you any idea, what I'm gonna do ? Sincerely Keld Friis

Hello,

Emails with a "To: undisclosed-recipients:;" header show no recipient information in the app, just as if there was no "To" header. Wouldn’t it be useful to display something to distinguish the two use-casesA?

After the recent update, I have duplicated icons for K9. I exported my settings and reinstalled the app, then re-imported my settings. All my email accounts came back. However, only one works the rest fail authentication. I think I can fix that. However, the one account that does work, downloads every email 3 times. I have some email that have come down 6 times. How do I stop that. I have used K9 for years with no problems until now.

Gestern hat ALLES noch funktioniert und heute erscheint diese Fehlermeldung Ich habe keine Ahnung, was zu tun ist.

Ich hoffe, dass Ihr mir helfen könnt Dringende E-Mails warten auf Bearbeitung.

Tausend Dank für Eure Unterstützung

I have v.13 of Thunderbord for Android Outgoing server settings match those recommended by Rogers/Yahoo, except that there is no Password field. App says SMTP server settings are valid, but when I try to send I get "Mailbox unavailable" error.

I'm using the Thunderbird Android App and I would like to highlight incoming messages from a specific sender and ideally receive a push notification. I would also like to increase the interval for checking/updating my email account linked to Thunderbird. How do I do this?

Thanks for your help!
