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

I like very much Thunderbird very much, but I had to move recently to use an Android device, that is my main computer now. I normally work with four email accounts, and I sometimes need to move emails across different accounts. I found out that it is not working on the mobile app. Are there any plans to include this functionality in Thunderbird? Thank you very much.

I currently have Thunderbird installed on both my android and desktop (W11). My android inbox does not mirror my desktop. For example, desktop inbox shows many more emails than the android inbox. The ones that are in both are the same. Why doesn't the android inbox mirror the desktop version?

Additionally, I used receive a ton of junk mail when using Edison mail. Now I receive very little. Sounds like a good thing but occasionally one gets flagged as span and it isn't. They continue to show up in the Edison mail spam folder but not in Thunderbird.

I was hoping to drop Edison mail and use Thunderbird exclusively, but I need the confidence before doing so.

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?

I've been using Thunderbird since it was first made available for Android, and I've used it successfully until recently. I have a new Outlook email address that I cannot sign into even though the Outlook email I have been using with Thunderbird since the beginning has never given me any issues. I get the "user authenticated but not connected" error. What can I do to resolve this issue so that I can have all my emails together in one app. Just to make things clear my old Outlook account which uses the email in writing you from connects flawlessly. It's a new one that is giving me issues. Any help would be greatly appreciated. Thank you for your time.

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.

Thunderbird for Android: When sending a message, the copy moved to the Sent folder is not marked as "read" after moving. Messages sent from the Android client and subsequently auto-filed into "Sent" or "Sent Mail" are still marked as "unread" after the move. They should be marked as "read" as part of the move, just like with the Windows client. I've searched the various Settings and I can't find any related setting.

Thank you for your attention to this matter,

Tbird (v16. 1) for android installed on my Pixel 9a connected to my gmail account. Gmail client runs perfectly connected to same account while Tbird starts with a blank screen i.e no messages. App appears to be frozen but later displays messages. General operation seems sluggish - enough to turn me back to the Gmail client (which I don't like) but at least I can navigate my email without waiting. Any suggestions please?

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?
