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

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.

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!

Version thunderbird 128.5.0esr 32 bits

Many moons ago I used Microsoft's Outlook as my email program. When I would open Outlook, it would retrieve all of my emails from my ISP's server, permanently removing the emails from the server while downloading them into Outlook.

When I installed Thunderbird recently, it was to do the same thing. My ISP had sent me several notices that my email account was close to full, so I was looking for an email program that worked the same way Outlook does, and removes my emails from my ISP's email server as it downloads them to my PC.

The first issue I'm having is that Thunderbird does not appear to do this? Or do I simply have my Thunderbird account/settings set up incorrectly?

My next issue is directly tied to the first one. Every time I open Thunderbird it starts re-downloading all of the emails that it has previously already copied into my Thunderbird Inbox, but that are still in my email account on my ISP's email server. This is probably 15 years worth of emails and equates to thousands of emails I'm saving, and every time I open Thunderbird it starts re-downloading them again. I simply want to be able to save them to my local email client (Thunderbird) and store them on my PC's hard drive.

The final issue is also tied to the first two: As soon as it starts downloading the emails again, Thunderbird (and only Thunderbird) lags heavily and almost continuously. It lags so badly that it becomes incredibly difficult to write a new email in Thunderbird, and so I end up closing the program and logging into my ISP's email server and using their client to write my emails, or conducting my email business via my phone, which takes longer and is more challenging due to continuous fat-fingering of the phones tiny little keyboard.

So, am I missing something, or do I have some settings in Thunderbird set up incorrectly? Or does Thunderbird simply not work the same way Outlook does (or at least use to)?

Thanks in advance for any help or advice anyone is willing to give.

Hello, I recently came back from being abroad to find out I am not able to send emails from my MAC computer. I am able to on my phone but not my computer. I had tried everything yesterday with our server guys and there is something on the Thunderbird side that is not allowing me to fix the issues.

If I log into the web mail, I am able to send e-mails.

How does one transfer addressbook entries from an old computer to a new one?

David from TB support wondered how I could get correspondence between help seekers and TB supporters when I followed the instructions I was given. I followed the instructions from November 9 and provided them in my email today. I suppose the problem is that I did/do not know how to place the entries from the old address book into a file that can be transferred from one computer to another. I assumed the file was abook.sqlite, automatically including all of my entries from the address book in the old computer. Apparently, this is not the case.

I need to know how to download into a file my entries from the address book in the old computer. Once that is done, I should be able to transfer that file to my new computer. I also need to know how to install the old entries into the new address book.

Thank you for your attention in this matter.

I'm having trouble authenticating and signing into Thunderbird with my work Gmail.

IMAP is already enabled and I've tried doing advanced configuration and changing both the inbound and outgoing server with OAuth2 authentication methods and still unable to connect.

I've tried multiple things found on threads and the community page here. Any potential solutions I should first be checking? Thanks for your help!

I'm unsure what settings should be set.

I have discovered that the emails in Thunderbird I have saved from earlier in 2024 are listed in Thunderbird but do not open for my talk talk and gmail accounts. Also some even older emails still open and some do not. How can I access them again via Thunderbird? I have attached two screen shot as an example to show how they are listed and what happens when I open the email.
