Thunderbird Community Forum

I've recently been experiencing a new problem with Thunderbird. As soon as I click on a subfolder in the left column that is bolded to indicate the presence of an unread email, the unread email immediately disappears. I can usually find it in either the Junk folder or in Trash. Is this possibly a bug in the latest update?

I am trying to setup an email account through Spectrum. My user name and password are correct, so I think the problem is in the server settings. Thunderbird has the settings as "mobile.charter.net". I have checked with Spectrum and this is correct. But Thunderbird says that something is still incorrect. Any advice on what I should do?

Hi everyone,

I've been using Thunderbird for a few months now and never had any problems until today when I've updated to 128.5.0esr. I'm using iCloud email and suddenly my Sent folder disappeared. When I started TB it showed up and disappeared after 2-3 seconds. It happened few times when I tried to restart TB however now it's permanently gone. I didn't change any settings and the folder is visible in Apple Mail or Spark, however it's gone from TB. Any idea what's going on? Please help.

Thanks, Szymon.

step we took: attempted to log in got error msg confirmed log in cred are correct used different email worked but, icloud issue pressit confirmed the server is correct

When I startup Thunderbird, it sometakes takes up to one minute.

I read on this forum that it maybe due to the linkes MacOS AdressBook. How can I "unlink" it?

Any other clues?

ANTIVIRUS turned off.

Hi, I have imported mbox file and Thunderbirds shows the initial view of messages. However, when I double click the mail to open the mail, I says :

File not found

Check the file name for capitalization or other typing errors.
   Check to see if the file was moved, renamed or deleted.

The file folder path isD:\Ortaklık\1_Mail\Mail_Retail The file name is RetailOmni_postalar002.mbox

I couldnt get why it says this error.

Could you please help? Thank you

I have never been a big fan of your products. However, i WAS curious about your email client, Thunderbird. So I decided to download it and try it out. THAT WAS A MISTAKE. I have a pretty good computer and have had vert little issues with other products from other companies. You products tend to freeze ALOT and I have spent the last 10 minutes attempting to enter my email information (e.g email and password) and keeps saying "UNABLE TO LOG IN AT SERVER, 'Probably wrong configuration username or password." I change the change the password and still nothing, so I manually entered protocol, hostname etc. and I am still getting same message. I check my firewall settings just be sure things were good. I checked with the my email and everything was ok there. What do wrong?

Od dwóch tygodni nie mogę wysłać wiadomości z żadnego konta email (mam 4 konta). Do tej pory wszystko działało, a używam Thunderbirda już 25 lat. Pozdrawiam, Janusz Kusztelak

Hi I started my Thunderbird on my laptop today 2024-11-26. However, last emails are from 2024-11-19, i.e 7 days ago.

I don't see what's wrong. No filters, strange sorting or similar are applied. When I login to same mailadress via webmail instead, everything works. There I have many mails between 19th Nov until today 26th Nov.

Any ideas what can be wrong? /Best Regards Joakim

There a $21.40 charge on my CC statement for MZLA Thunderbird email. I had no idea who or what Thunderbird was until looking online. Found the website and saw Thunderbird is a "free" email app. My Verizon rep added it to my new iPhone 16 when it wouldn't send emails via my normal email provider (breezeline.net). I was not told the app was being installed, or that there is a fee for use it. He handed me back my phone and I saw a new gmail account had been added. What is the charge for? And why was I charged?

The Menu at the top of e-mail to be sent disappeared so I can's send e-mail. I was able to click "File" and then click "Send Now" for a few days but the menu bar just disappeared. k.blair@sunflower.com

I’m having some issues with Thunderbird. It’s running really slowly and making my whole computer lag. Thunderbird consumes constantly 8-9% CPU while it’s on. I’m using Windows 11 and Thunderbird version 128.4.3.esr (64-bit) on a laptop with fast NVMe drives.

I’ve added 8 email accounts, and the mail folder (Roaming/Thunderbird) is about 165 GB right now. I think it’ll go over 200 GB once all the messages finish downloading.

The problem seems to be with message indexing. The Activity Manager shows it’s indexing over 300k messages. Even if I leave Thunderbird running all night, it doesn’t finish. When I get new emails in the morning, the indexing starts all over again. It takes hours and uses a lot of CPU while it’s happening.

If I disable the "Enable Global Search and Indexer" option, Thunderbird works fast and smooth, and CPU usage drops a lot. But, I assume, this means I lose the ability to search emails.

When the lagging happens, opening an email preview can take up to 3 seconds (!), and deleting a message also takes 2-3 seconds. However, when I disable the "Enable Global Search and Indexer" option, Thunderbird works ultra-fast. Opening and deleting messages is instant, and there’s no delay.

Any idea how to fix this?

Hello,

My setup is an old win7

2 days ago I got a power outage. When I turned my PC back on, thunderbird updated itself to 115.16.3 (32 bits) I am not sure which version it previously was.

Anyway, I have 4 profiles, the 3 profiles I was not connected on when the PC crashed are fine, totally unaffected. That should be a hint. My main profile was connected at the time, in fact I was writing an email when the crash occured. When back on I executed thunderbird I chose my main profil. I was immediately prompted with a 'welcome to thunderbird' asking me to input my credencials. I immediately closed TB scanned my disk for issues, checked my profiles folder which appeared to be fine. I indeed have a folder named hnych9cb.default in my %APPDATA%\Roaming\Thunderbird\Profiles which is was 2.2Go.

Then I had the (bad?) idea to input my credencials as asked thinking it might help TB to connect to the folders/emails inside my profile folder. I did but instead it downloaded and displayed the folders/emails as they are on my email server and now my hnych9cb.default is 3.7Go ....

This is a mess

Is there any way or hint to save the day ?

Help! Why are my gmail emails inbox and sent not showing up since 11/18/24 ?? I have shut down several times now. I have attached a screen shot of my server settings. Does that show something? Im running windows 7 professional Thank you!

I've been using Thunderbird on my PC (Win 10) for many years, and the email does not download today. I tried reconfiguring the server settings but it says: The stat command did not succeed. Servier unavailable 21

Could anyone please help Thank you Mario

Please excuse my wording as I don't know all the correct terminology. I have several email addresses with our current local phone company with our landline/internet package. Since the internet service is so poor, I would like to discontinue this internet service and go with something like Comcast. Once we cancel our internet service with our local phone company, we can no longer use those emails addresses (name@embarqmail.com).

I'm trying to find the best provider that supports POP3 protocol as that works best for our household. And I'll need to set those email addresses up BEFORE I cancel with our local company. Can I set up emails with Thunderbird (name@thunderbird.com) or should I go with something like Gmail or Outlook or Yahoo? Trying to find the best solution so we don't have to do this again if we change internet providers.

I already do have one Gmail account and it says it supports POP3 protocol - but it doesn't always work - sometimes I get an email on my phone that doesn't come through on my desktop computer - and you have to type Recent: while setting up the account.

Any help would be greatly appreciated! Thank you!
