I have the Android T-bird app on my Google Pixel 9.

I am having constant problems with it not syncing.

This morning, when I swiped down, the kept spinning but did not connect. When i tapped the sync icon at the bottom left of the screen, nothing!

Nothing changed after rebooting the phone, which BTW takes almost twice as long as the reboot on my previous Samsung phones.

I have now uninstalled and reinstalled, and imported my settings using the QR code on my desktop. It imported my accounts, but asked me to sign in or sign in later. There is no link for signing in immediately, and sign in later does not allow any sign in opportunity.

I now have no emails imported to the app.

Any help would be appreciated

Hello, when I try to login to my outlook.cz mail account, I get error screen that says: Server error The server returned the following message: User is authenticated but not connected. I searched online and I found, that I wasn't the only one getting this error. Everyone solved it by disabling ipv6 in thunderbird. I don't know how to do that on phone (I found how to disable it on pc). I have another outlook.cz account that I am logged into and it works fine (I logged in 2 weeks ago). Is it thunderbird problem or should I contact microsoft. Thank you in advance for your answers.

I have TB Mobile for Android Version 8.2 on my Samsung A54 running Android 14. I have done numerous searches, but can not find any way to move an email that I accidentally sent to Trash or Spam back to Inbox (or any other folder for that matter). Am I missing something or is this feature simply not available?

I can do the above with my Yahoo mail on my A54 which has a menu that lets me move any email from folder to folder.

Thanks for any help.

As email threads become lengthy they become unreadable. The older emails turn into displaying one character per line. Is this a bug or something fixable on my end?

I installed Thunderbird for Android today on my Moto g stylus. I used the QR code to import the settings from Thunderbird on my Windows 10 laptop. In general, things seem to be working, but outgoing messages are not being copied to the "sent" folder. I can see older "sent" messages that were sent from my Windows 10 Thunderbird, but no sent messages that originated from my phone. I have an IMAP mail server.

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

One Gmail account imported all of the settings, including the Inbox. The other Gmail account recieves this:

Please sign in We'll redirect you to your email provider to sign in. You need to grant the app access to your email account.

Sign in with Google

Then the following error, as it won't open to Google to confirm (it did with the other account)

Please sign in Oauth sign in failed OAuth 2.0 is currently not supported with this provider Retry

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.

Thunderbird Android v8.2 / Pixel 6a / Android 15 (Feb 2025 security update)

IMAP Push in use for Inboxes only on 3 mail accounts (2 Comcast; 1 Gmail)

  - Enable Push: "on"
  - Enable sync: "off" (for Inboxes; on for all other mail folders)

Installed TB in November 2024 and experienced no problems until recently. Beginning in early February 2025, inbox push/update stops working every ~24 hours. If I go to Android settings and force stop TB, clear cache, then restart TB, Inboxes immediately sync with servers and again function fine for approximately 24 hours (not exactly).

Using TB for 3 e-mail accounts. Only the 3 Inboxes have push enabled (and sync disabled). All other mail folders on each account set to sync every 60 minutes. This configuration was set up on initial installation and worked without issue until recently. The only system modification made in this timeframe was installing the February 2025 Android security update.

Anyone else experiencing similar issues? Any suggestions?

Thank you.

Hi. I have Thunderbird installed on my Galaxy S25 phone and Galaxy Tab S8 tablet. If I send an email from either of those 2 devices 2 copies of the same message appear in the 'Sent Items' folder. Two messages also appear in the 'Sent Items' folder of Outlook on my PC. If I send a message from Outlook on my PC only 1 message appears (as it should do). Is there something that can be done to correct this so that the message only appears once? Kind regards, Paul Goddard

I have downloaded Thunderbird Android and want to write an email but my address book doesn't seem to work when I start writing into the address ("to") field. How do I connect my address book to Thunderbird?

HI I have the latest Thunderbird installed on my Redmi Note 8 Pro (Android 11). When I try to write an email and add an attachment (e.g., a photo), the system file manager opens. After selecting the file, it doesn't appear in Thunderbird. Sharing a file from the file manager via Thunderbird results in the same issue. Only when sharing a file through the system Gallery app to Thunderbird can I attach and send it successfully. In the permissions settings for Thunderbird, I only see options for Camera and Contacts. There is no option for Files and Media. I couldn't find a solution to this problem anywhere. Does anyone have any suggestions?

Every time I open a message I'm presented with the 'Show remote images' button which I have to click on to see the images in the email. I understand this is a security issue, but like the desktop version, I thought there might be an option to 'allow remote content' from the origin that would be remembered for all future correspondence. Is there a way to eliminate the need to always click on 'Show remote images'?

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 can receive and send now from Thunderbird for Android, although I have to bypass the VPN to send. I have no trouble replying to an individual, but where do I find Reply to All?
