Thunderbird for Android Community Forum

Hi All, I have been sending emails through Android Thunderbird, but they aren't being synced to the server, so I can't see them anywhere else. I've set the Sent folder to sync (as well as the Inbox). Pressing the sync button just spins the indicator, but doesn't actually sync. When I try to move or copy messages, an error comes up saying that messages can't be copied or moved that aren't synconised. How can all my messages (sent, inbox, everything) be synced so that I can see them everywhere? I've just turned on sync debugging, will see the results soon.

Hi there, I recently switched to thunderbird and it's been working great on Windows desktop but try as I may I can get it to work on android. I followed the prompts to export the settings and that all seemed to work but the app won't connect to the incoming and outgoing servers. I've checked and the details are the same as the desktop (via Bridge) but it just says failed to connect every time.

I'm also only showing an outbox and no other folders in the app. I searched the forum and found others with this issue but no solutions. Is this a dead end and I'm better off going back to Outlook or is there a solution to this?

Thanks in advance 😊

Hi,

Every time the phone was sleeping, i need to restart TB, or it will not refresh imap folders (3 accounts active, one icloud).

Once it gets restarted, everything is working as expected.

What to do?

Best regards,

Andy

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?

I've been using the Thunderbird App (v12.1) on a Google Pixel 8 (Android 16) for a while now with several Email accounts from different providers. One of them is a T-Online Email address. Recently it appears to have stopped syncing the folders only for this account. I still get emails in the inbox but all the folders are empty. It only says "Bis zu 100 weitere abrufen" (request up to 100 more) but tapping that doesn't make a difference. In the settings I have the sync set to everything without limitation.

I tested the same account with K9 (v11.1) and Google Mail and in both all the folders have their content.

Does anyone have the same issue or any suggestions? Is there any logging that I turn on to see if there's any errors?

Thanks!

I use thunderbird in UK with several emails accounts. Works splendidly on desktop and mobile. Now in Greece I can neither send or receive emails on any account. But Gmail and outlook work fine. Is there a firewall problem or similar? Thanks

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 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

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.

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.
