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?

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?

Hello there I have Thunderbird for Android, version 10.1, and in every folder, all mail, both read and unread, have almost the same appearance. It's not easy to tell which ones in the list are read and which are unread. Is there any setting to turn the unread messages in the folder look highlighted, or more bold, or something different anyway than the rest? Because this way it's very inconvenient, which makes me considering turning back to Outlook. Thanks in advance

Hello guys,

I've been a passionate user of (and advocate for) Thunderbird for more than 20 years now and was quite delighted when Thunderbird for Mobile was launched. At last I could use Thunderbird on my phone and tablet as well as my desktop! I've used Bluemail (the best of the rest in my view) on my mobile for some time and am currently comparing its performance side by side with Thunderbird for Mobile, having just installed the latter. In terms of fetching message I'm actually finding Bluemail much speedier at the moment and don't know why this is so. For example, I can often read incoming emails on Bluemail five minutes or more before they arrive via Thunderbird. So far as I know, I think I've tweaked all the necessary settings on Thunderbird but may be overlooking something. Can anybody suggest a way to speed up Thunderbird? I'm more than keen to keep on using it.

Cheers,

Grant

I have Thunderbird on my windows desktop and it is excellent. I can not use Thunderbird on my iphone but I have been told it is available for Android phones. If I get a new Samsung phone will I be able to have contacts, calendar and email on it as I have on my windows desktop? I do not use Outlook on desktop or iphone. Thanks for any help! Greg

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, Mi 9 SE with MIUI 12.5.1 Android 11 RKQ1.200826.002 Thunderbird 10.0

I moved from K9 to Thunderbird some time ago without incident. In the last few days I realised I had received nothing and checked on my PC and indeed mails were waiting. I tried to send a test mail from the phone, the mail remained in the OUTBOX and I received the following error message :- "Failed to send some messages ErrnoException: connect failed: EACCES (permission denied)" I checked and this is an Android error and various articles I found that suggest necessary changes to the manifest which I am not capable to change; I am not a coder. I decided to save the configuration, delete and reinstall Thunderbird. After this and reapplying the passwords the waiting mails were delivered. I then tried to send a test message from the phone and again the same error was generated with the phone blocked again from sending or receiving.

I suspect that there was an upgrade applied with a changed manifest that broke the operation of Thunderbird with Android 11.

Can someone please verify this, it may be impacting many installations on older phones?

Many thanks!

Hello, for the last week my Thunderbird android is no longer sending mail.

I revoved and add it again my mailbox. On the SMTP validation I receive this error message: Unexpected end of string

Setup is not finishing.

Trying on here, as I suspect the android forum gets little attention.

I can send email with TB for Android over the Internet from home, but not over the Internet in 4 out of 4 cafes. it's not due to a VPN. It only happens eith Thunderbird, not Gmail or Outlook.

I have setup Thunderbird to check for e-mail each 30 minutes. But I never get any notifications of any new mails :-( And mails are only downloaded when I start the app and swipe down. Folders are setup to sync (but "push" is not enabled). Power settings are set to "Optimized" (works for all other apps that check for things).

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.
