Buen dia, tengo inconvenientes con errores en la aplicación debido a que surgen en algunos mails error en una parte de la firma. Adjunto imágenes, (el mail que se encuentra en amarillo está mal/incorrecto) mientras que luego el que se encuentra de color verde es el correcto. Lo más raro y un punto a tener en cuenta es que hay algunos mails que salen en el mismo minuto y uno tiene bien la firma y la otra no, es decir, que es de forma aleatoria. Me podrian indicar los motivos y cómo arreglarlo?? Gracias

I am being told by Microsoft that in order to use the New Outlook, I have to sync my IMAP to the cloud, so I'm looking for an alternative email client that allows me to work offline with pst/ost files. Does Thunderbird allow this? Also very concerned about data breaches and security. Thanks!

Hi, I use Thunderbird for Android Beta 12.0b6 and I have the following problems: 1. Most of the emails I deleted from the notification shade still show in my inbox when opening the app.

2. Since the last update, the gestures work poorly, I have to swipe 2 or 3 times in order to delete an email.

Please have a look into it when you have the time. Thanks

Two emails from 2020 and 2021 remain at the top of the main inbox. I have tried deleting and re-adding the Naver account. The problem still exists. I have attached screenshots showing when these two emails arrived in my main inbox and the current problem I am reporting.

Please help me correct this bug.

Iam unable to find how/where to create additional folders. With desktop version I have created a number of folders. I like organize and segregate my emails into various groups. Especially the ones I choose to preserve rather than delete.

New incoming emails are no longer marked as "unread" and In bold print when they arrive. I have to manually mark them as unread. Then when I read them, they do not consistently change to "read". This was not a problem until I started using the 128.10.0esr (64-bit) version of Thunderbird.

I'm on 141.0 (64 bit). I'm trying to create a mail folder (right click on "Local Folders", "New Folder"option). As I type the name, when I exceed eight positions the "Create Folder" tab goes dark. In other words, you can't create a folder with a name longer than eight positions. This is new.

SORRY, this is my error. I'm embarrassed to say what it was. I was trying to create a new folder, but a folder with the same name already existed. Duh........

I would delete this question but I don't see a way to do it.

I've contacted the volunteers before when my follow-up on a problem wasn't resolved. I haven't had any answers or suggestions since. I don't know what I did to create the problem a couple of weeks ago, while I was trying to change the chronological order of receiving current emails. I wanted the most recent messages at the top with the oldest at the bottom (descending?). The whole system froze; when I rebooted and reopened Thunderbird I discovered that all the folders used for saved messages appeared to be empty. Moreover, every time I read a message in the recent panel it would also "disappear" as soon as I closed it to read another message. One of the volunteers suggested a method to retrieve the lost messages in the folders. I followed his instructions and when I got to the "repair" button, it was grayed out and didn't function, so I'm at a loss. So far as the most recent messages are concerned: very few are displayed in that file. I can only read them now in "All messages". For the first time since I've been a Thunderbird user, I've been forced to go to Gmail through Google and I really miss the Thunderbird platform's features. I hope someone can help sort out my problems.

Hi, since Thunderbird 141, tbsync add-on is no more possible. So : how it is possible to sync Hotmail contacts (and calendar) ? What is the way for setting this ? Thank you for your answers.

my current ISP, Livingston Communications is closing it's offices and all services. Are you a service provider or do I need to go over the Netscape or something? At 83 all this tech stuff can be confusing. Please help or advise. Thank you

Hello all!

I use Thunderbird as a local archive for my email. I have two accounts in the application: my home email via my ISP (POP) which I predominately use and my gmail (IMAP) which I don't generally use. There are years of messages in folders and sub-folder under the POP account, but nothing under the IMAP.

I’m up to date with Thunderbird at v140.1.0esr (aarch64) on my iMac with Sequoia 15.8.

On 07/22/2025 I went to download some messages via my ISP POP account and saw that a whole bunch of my email folders no longer had any subfolders and were empty of any messages. Some were also duplicated. Please see the attached image.

I haven’t changed any settings in years, and I do not have any add-ins. One of the nice things about Thunderbird has been its solidity and simplicity.

After every session, I would empty my trash and compact.

Suddenly my email seems to be gone along with sub-folders while top level folders are duplicated.

Wondering if anyone has any suggestions on how to troubleshoot this? Since I don't do anything fancy with the application and with the suddenness of this issue, I can't image I'm the only person having it? I’m quite concerned I may lose many years’ worth of messages.

Thanks much in advance! CPRoot

I know how to create a new folder in my inbox; I have done it a handful of times.

Left click on Inbox Click on New Folder Type in a name in appropriate box "Create Folder" goes from pinkish to red, so I click on it....

And the folder never appears. What obvious thing am I doing wrong??
