Today I started to receive this error message when I went to download emails from my aol account to thunderbird. This is the first time this has happened. "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." We have plenty of disk space so that can't be the problem. I could see many other people are experiencing this problem and there seem to be a variety of solutions depending on the circumstances. We are on Windows 11, we don't have McAfee installed but us Norton antivirus. I tried checking the settings, I've rebooted, and not sure what else to do. I can't remember some of the other comments I read. However, I am not technical and couldn't understand most of the suggested solutions. How do I get remedial help to figure this out?

I do all my email on my computer but I do have Tbird on my cellphone too, just in case I have to send something. But I never download. So I was in a situation where a government process included 'check your email' and I had only my cellphone with me. So I started downloading: 25 more, 25 more, 25 more ... and a hundred presses latter it's still not finished. Is there some way to reset that? I'm back with my computer and my email seem fine, but the cellphone remains stuck.

will not download -- "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've mucked up and Email Account and whilst trying to solve it, I have found where the Return-Path: email address is listed as a very old email address that is no longer active on any server.

So I'm looking at how to update it??

I'm a newbie. I am financially obligated to have an ATT/Yahoo email acct. It is 2-factor ID. Can't properly save and utilize the email there, but must keep acct. Need to set up Thunderbird so that I can transfer/save those emails to Thunderbird. ZERO help from Yahoo... If it is possible to do, hoping someone can give easy steps to accomplish. I can try to explain further... If so, very many THANKS beforehand. scooter

all emails that I send have no text appears, but 1 attachment shows. Click on the attachment and the text appears. I wanted the text showed in the email not attachment.

Aloha. I'm helping a friend with setting up a new Windows 11 PC, and cannot get Thunderbird to connect to Spectrum's servers. I spent an hour on the phone with Spectrum support and they just gave up and said it must be an issue with Thunderbird. Here are the details:

- Brand new Dell 24 All-in-One EC24250 - Windows 11 25H2 plus all additional fixes. - All Dell drivers updated. - Thunderbird V155.0 64-bit

If I click on 'Get Messages' after a while I get: "Connection to server mail.twc.com timed out". I've gone into the config editor and changed mailnews.tcptimeout from 100 to 500 and still get the error.

In the Account Settings | Server Settings | Test server connection I get: An error occurred connecting to mail.twc.com:993.

I've tried this with both setting up a brand new account in Thunderbird, and also via copying the 'Thunderbird' folder from %appdata%\roaming from her old machine.

Email configuration (from Spectrum).

IMAP Settings Server name: mail.twc.com Port: 993 user name: abcd@hawaii.rr.com Connection Security: SSL/TLS Authentication method: Normal password

SMTP settings Server Name: mail.twc.com Port 587 Connection Security: STARTTLS Authentication method: Normal password

Can anyone help me troubleshoot this scenario?

PLEASE BE PATIENT WITH ME. I am elderly, and am struggling greatly. Within the last week, I can’t send emails from my Mozilla account. I have a BT email address ie btinternet.com. When sending, it comes up with Login to server mail.btinternet.com wth username (my email address) failed. This is followed by Unable to authenticate to outgoing server (SMTP) Please check the password and verify the authentication method in account settings / outgoing server SMTP.

I was on the phone to BT for three hours yesterday and they were so lovely and patient, they set me up wth a BT email app, however all of my folders with my vital bits and bobs are on Mozilla. Please could someone help me

Thunderbird has been working well, but all of a sudden it stopped sending my emails from aol accounts. I have tried many internet solutions and nothing is working.

My Thunderbird Account was updated by TB on 2 September. Since then all of my new emails go to Trash. Although I've tried the various responses to such questions, I've been unable to change the problem and get my new emails to come into my Inbox. I'd very much like your assistance please. Thank you.

I would like to setup Thunderbird as my email client.My email service is provided by Godaddy with an Outlook account. When I am at the incoming server settings, it has my domain name, not smtp.office365.com which I tried with both authentication options (below) and with my domain name, the protocol was IMAP. I changed the port from 143 to 993. I changed security from Autodetect to SSL/TLS. For authentication, there was not an OAuth2 option, I tried Autodetect and Normal password, neither worked. And I used my domain email password. with using my domain name, it came back with an error an suffixed my domain name with :110. It stated that this was not the correct domain and there was a security issue. It is not clear how I should progress.

I've been using TB for years and all has been working well. But now I have no idea what is going on.

When I try to download new email from my Yahoo account (using pop3) it tells me that it is downloading 1 or 25 (say) and none get downloaded.

Then I delete some emails in TB and a little while later those deleted emails get downloaded again but none of the latest emails. Even if I logiin to Yahoo and delete those emails, TB seems to manage to download them again. How?

If I delete the first email it should download sometimes the rest will download but not always. Sometimes when I update to the latest version of TB emails start downloading.

I have tried to doing a repair on the Inbox but this seems to make no difference.

I've no idea what to try. Anyone got any advice/suggestions?

Also, how do I get from the Beta version of TB to the stable version? I don't even remember choosing to use the Beta versions.

Lastly, I often get pop-up messages saying that folders cannot be compacted because something is using those folders. I've never understood why TB puts out this message. Why does it not just compact the folders when it has done whatever it is doing? Is there a way of stopping these messages and finding out what is using the folders?

When replying to an email or sending a new mail I get the message :- An error occurred while sending mail. Server responded : You need to authenticate when sending mail from (ip address) Please check "message Recipient" and try again. How do I authenticate ? Thanks140.7.1

These are some things I have explored:

   • It is happening whether I look at emails in Thunderbird or through Gmail on Google Chrome
   • Even if I clickndrag them from deleted to inbox they fall back into deleted.
   • I’ve tried gmail/settings/all settings/filters and there aren’t any
   • I’ve tried gmail/settings/all settings/forwarding and there aren’t any
   • If I access Gmail via Microsoft Edge, the emails stay in Inbox
   • I’ve looked at various things in Thunderbird and unticked something in ‘When New emails arrive’ because I thought that might work.  

It started happening about a week ago.

As the title says, over the last two days Thunderbird won't do SMTP authentication to Outlook. It has worked happily for years and nothing at my end has changed.

I've the latest version of Thunderbird - 140.15.0esr (64-bit) - and this is Windows 11. It works happily from the Outlook desktop so the password is correct.

The authentication method is OAth2 and connection security is STARTTLS. Server is smtp.office365.com and port 587.

Anyone else having issues? Presumably MS have changed something (again)

Has anyone any suggestions on how to resolve?
