I'm blocked by cbl.mailcore.net, so I can't receive my mail. I've contacted spamhause but I still can't get the thing to work. So have you any idea, what I'm gonna do ? Sincerely Keld Friis

I have v.13 of Thunderbord for Android Outgoing server settings match those recommended by Rogers/Yahoo, except that there is no Password field. App says SMTP server settings are valid, but when I try to send I get "Mailbox unavailable" error.

Would love if someone could please help me with this. It worked perfectly fine adding one Outlook account but this one for some reason just isn't working. It'll bring me to the Outlook sign in to give permissions then throws the error (attached image)

Hi,

Since updating to Thunderbird 140.7.1esr (64-bit) on Windows 11, moving messages from Inbox to any folder takes about 7 seconds.

Details:

Account type: IMAP (Cogeco)

Happens in all folders

Inbox has ~600 messages (not large)

Was working normally before the recent update

Delay occurs every time moving a message from Inbox to another folder

No freezing — just a delay before the move completes

No antivirus changes

Issue started immediately after update

This appears to be related to IMAP sync behavior introduced in 140.x.

Has anyone else reported this, or is there a known regression?

Thank you.

I have just installed Thunderbird on my Android phone and using my desktop Thunderbird exported my email address to the Thunderbird mobile. This worked OK. Just for the record, this is my first time with Android version of the Thunderbird, and I can't find the inbox folder. Could you please guide me how to do it? Many thanks.

When I first open K9Mail 16.0 or after scrolling to the top of the message list, the message does not disappear from the list after I open a message, select move, and choose a folder. The message will no longer be clickable after I do this. However, it will remain displaying in the list until I start scrolling the message list, at which point the list updates and removes the moved message.

Please fix this bug.

Thanks.

I have used Thunderbird on my desktop PC for many years, and have now installed it on a Lenovo tablet running Android. The setting up was simple (thank you), and I am receiving emails with no problem. I have tried sending emails and they are simple to type up, but there is no visible "Send" button. I have accidentally sent an email successfully, but have no idea of how this came about. Please help me to send emails, as I am very keen to use the tablet fully. Many thanks, Nigel Olliver.

Recently started using Thunderbird on Pixel 9a, Android v16. Just installed newest update to OS. Emails do not sync properly. New messages that are in my Gmail do not show up in Thunderbird until I do a manual update. This is true for all folders, but especially trash and spam. For example, messages that appeared in my Gmail trash folder this morning did not show up in Thunderbird trash at 7 pm MST this evening. When I did a manual sync, 10 messages from this morning suddenly showed up in Thunderbird. In Thunderbird settings, Background sync is set for Always. What do I need to do?

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.

I have set all Notifications on (there seems to be a dozen on/off switches) but new emails do not trigger a marker on the Thunderbird logo or any other form of notification I have to open Thunderbird just to get new messages to download Is there a setting I need to change?

Bonjour à tous, Je cherche comment afficher images distantes par défaut. Jusque là, elles sont cachées et un message s'ajoute : les visualisation des mails ouverts est inutilement compliquée (à mon sens, le principe de sécurité, annoncé à chaque fois à ce sujet, n'est pas adapté.). Merci de m'aider à grive fer le moyen de mettre automatique des "images distantes" par défaut 😊. Bonne journée !

I still don't get links in my emails I have tried everything in the forum but no luck I actually get the expanded version. This is only the case with the android app

i still can't believe there is no way to print emails in your mobile app. I even downloaded the beta, but it also gave me no way to print an email. What's my money going to? I've seen many people ask for this its such a basic operation. I'm hoping you will get this, or I will have to change to another program

In V.10, it used to be I had to really swipe all the way left for delete to occur.

Now in V.13 only a small/partial movement deletes.

This is tool easy to mis-trigger. Please go back.

Thanks

I'm looking for the Thunderbird for Android user manual. Is there something like that available to read? All I found was scattered FAQs.

No, I don't have a specific question. I just want to read the whole manual.
