Hi all,

I have tried on K9, and Thunderbird Mobile.

On my tablet, with K9 mail, I exported my fully working accounts, and imported to my phone. All worked, except one account, where it only has an outbox. No inbox, no sent folder, nothing.

I then Installed Thunderbird mobile, and used the QR code link in the desktop app, to sync to it. Same issue. All other accounts work fine, but not that one account. Only an outbox.

I've logged into the web version of that account, and no restrictions are on folders. And it's only on my phone. On tablet it's fine.

I can't even choose folders in settings, for sent, etc, as there are none to choose.

Any help would be greatly appreciated. Thank you

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 have a POP3 account setup on my laptop and recently downloaded the thunderbird mobile app for android on my phone. I setup the android mobile app as IMAP to access the same server account as my POP3 laptop. When I look at my thunderbird phone email notifications in the morning, I compare them to the emails in my inbox on my laptop and find that the emails I see on my phone DO NOT show up in my inbox on my laptop ? I thought IMAP was NOT supposed to delete messages on the server when retrieved to my phone. My intent was to just read emails remotely on my phone but leave them on the server. I want my POP3 laptop account to see all of my emails and control whether to delete them or not after reading.

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?

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.

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?

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

I just installed Thunderbird 12.0 on my Phone (Galaxy Note20, Android 13). Account setting were taken from my Desktop PC using the QR Code. In all three Accounts only Mails in the Main IMAP-Inbox are shown. Subfolders (like "sent" or "drafts") are all found, but the messages inside will not be shown. It will only say "Load more messages" but does not find any. In K9-Maiil 11.1 this still worked, but I had to uninstall it as after the automatic update to 12.0 it suddenly kept crashing on startup.

Already tried to add my main account from scratch on my tablet (with a fresh install of Thunderbird 12.0), but the problem with empty subfolders remains.

Any thoughts on this?

Hi All,

I am installing Thunderbird from official GitHub releases and I am wondering why I am getting info from Obtainium that thunderbird-14.0 is something called "pseudo-release".

Can someone explain me this term regarding GitHub apk files? Is it OK to install it?

Regards, Timo

Hi,

After the installation of thunderbird in android all went well.

Then i try to sync all folders , 300, from my google account.

It seem is not like windows/linux, where you use the right button on the account and the process move on.

In android looks i can achive this, but doing one folder at time.

Is there any way to do this at once ?

Best regards Rui Pimentel

Hello! It seems like Thunderbird must have updated on my phone and somehow my Sent folder is now not only empty but no longer syncs with email account. It worked perfectly fine until just the other day and now I can't tell what needs to be changed in my settings since I don't know what caused the problem! :( I've tried resyncing, cache clearing and force stopping but I can't think of what else I should do. Any help is greatly appreciated! Thank you.

I can't find in mobile Thunderbird address book. It is not convenient to fill manually Adresse of Adressat to write email. There's no way to keep email address of people in email in non existent address book. Can you help?

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?

What I delete an email message on my phone, it disappears in my app. But when I check on my computer and in my old email app, the deleted message is still there.

I've checked in multiple email accounts and multiple messages.

Thanks Jim King

I have been using Thunderbird as my mail service for many years, using it on the PC and my smartphone. Since several weeks ago, for an unknown reason, the "SENT" folder on the smartphone shows all the messages which were sent, but not with the correct name of the person/organization to who the email was sent. All my messages in the "SENT" folder are recorded as having been sent to "Lucie Payant" with a picture of her avatar, instead of showing the name of the real correspondent.

However, the "SENT" folder on my PC is fine and shows the correct correspondent to whom the email was sent to.

I verified all my settings, and, as far as I know, everything seems correct on my cell. This situation is very annoying and confusing.

Can you help me please. Raymond
