Thunderbird Community Forum

Came back from an errand earlier this morning and after turning on my Mac again, found that Thunderbird 115.10.1 was prompting me for my username and password at the web page for my account, using a pop-up Safari window. But trying to do that doesn't work because my version of macOS is not supported by Yahoo! Mail anymore.

So I tried deleting the account and adding it back, since this is the very first time it's ever done this, but that doesn't work, either, because Thunderbird still prompts me for the same username and password using the same Safari window that won't work anymore.

Tried updating Thunderbird to 115.16.3, but that makes no difference; still can't send or receive email.

Who's idea was this, and why did nobody consider that web sites have dropped support for many older browsers that can't be upgraded, and give you no option to use a browser of your choice that would work for this, even though it should never be required?

How do I (or others that are affected) solve this problem once and for all?

SENDIN MESSAGE FAILED AN ERROR OCCURRED WHILE SENDINDING MAIL. THE MAIL SERVER RESPONDED; MAIL BOX FULL ... FAILED TO PROCESS MESSAGE DUE TO A PERMANENT EXCEPTION WITH MESSAGE... MICROSOFT UNITED STORAGE IS FULL

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.

Hi,

Why am I getting this message?

Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox.

I started the program this morning and got a small download. Left the program open and 30 minutes later tried another download. The program shut down last night without a problem. I have compacted the inbox and there is plenty of disk space. What is the problem? Allan

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?

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

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?

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!

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.

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.
