OK, so I have 4 different emails on my Thunderbird account. I get the most email from my usa.net (Netaddress.com) account, but that has never been an issue -- as my inbox gets huge I just move the contents into a dated archive.

I have already looped back to the people at usa.net and all of my settings are correct.

Here is the issue: Out of nowhere, a few months ago, when I tried to download my USA.net email, it would stop after 100-200 emails. Also, it would NOT "register back" to USA.net and show the downloaded items as "gone" (I checked my settings; I am NOT leaving email on the USA.net server).

I even tried deleting a ton of emails on the USA.net server side via webmail, and it still just stops after 200 messages max. I then need to dump out what was downloaded to another folder or I get the error below (see upload).

I hadn't changed anything on my settings when this started. USA.net DID start a requirement several months ago RE using SSL, but I didn't have problems when I initially made the switch.

Help, please! When it stops downloading I either get no message, or I sometimes get the message shown.

How to fix please? Again, this is the ONLY email account that I have this problem with; if some kind of "limit" was being hit it wouldn't be letting me download from other accounts, including my "business" email (basically I use USA.net for all of my newsletters, online purchases, etc).

Thanks so much.

Ok I know this has been asked before but I can't find a way to fix this. When I click on ANY link in an email or even the menus, not even the help menu works, I get a "no app associated" error. My file associations for .htm, .html, http, https are all set in the default apps in windows. I can click on an email address and it works just not any other type link. This is in version 144.

11 Nov. I am unable to send or receive e-mail using Thunderbird. I have a gmail e-mail address. When I want to open Thunderbird, I am required to log in using Google. This has just been the case for a few days. Previously, I never had to do this.

It does not work. I cannot log in using Google. I get "Error message 400".

My account settings are: outgoing server smtp.gmail.com incoming server: imap.gmail.com Port: 993 connectivity security: SSL/TLS Authentication: 0Auth. Is there something incorrect in the Account settings?

Sometimes I get a message saying "Authentication failure while connecting to server".

I saw something on line about Troubleshoot Mode for Thunderbird, but I can't get there.

I desperately need to solve this problem. I have used Thunderbird for many years, and have a lot of data in Local folders. I do not want to lose all this data. Thank you.

I suddenly this week cannot send email using Thunderbird (v. 140.4.0esr (64-bit)). I receive email fine. I can send email using webmail with my provider. Error message in Thunderbird is: "Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: resomta-h2p-555359.sys.comcast.net resomta-h2p-555359.sys.comcast.net ESMTP server not available (62240/216.183.125.238)." My provider says the issue is not at their end because my server settings are correct. Outgoing SMTP port is 465, connection security SSL/TLS. Operating Windows 11 v. 24H2.

Yesterday, my ameritech.net email stopped working in Thunderbird. I get an error saying it's unable to log into the server. The email account works from outlook, and from a web browser, so I know I'm using the right password. I've tried it on more than one computer and it's only Thunderbird that is having the problem. It's working with my gmail account. Any help would be appreciated.

Every time I open thunderbird I get a blank screen with this message, 'Edge: Too many requests' over the top of the thunderbird screen. This screen stays on my desktop after I close Thunderbird and I have to change my screen resolution in order to close the screen. Can you help please? Martyn Smith

I have been using Thunderbird to download my mail from Yahoo for a long time without incident. Now I keep getting the message "Edge: Too Many Requests" as a response when trying to download my email messages (see attached file). I waited 24 hours and then tried again but still get the same message. I am able to log on to Yahoo on my desktop and see my mail without a problem. Is there something that needs to be cleared or reset in Thunderbird? My other email accounts in Thunderbird work fine. Any ideas would be helpful.

Have used Thunderbird for years and 2 years ago, my Cox service eliminated supporting their own emails server and now Yahoo supports. I am having a problem over the past 2 weeks where I click on my Thunderbird app to load the program and get emails, and it times out after about a minute every time I try to log in. I have deleted the Thunderbird account and tried to add a new account, and it continues to time out every time.

What am I doing wrong?

I just downloaded Thunderbird and trying to setup my existing email. It keeps giving me the message "Unable to log into server. Probably wrong configuration, username or password. I just logged into my email on yahoo and the user name and password worked fine.

When attempting to access my emails on Mozilla Thunderbird i am met with a text box prompting me for my password, when I enter the password it informs me that is it unable to connect to the server. following guides online for similair issues it encourages you to change your authentication to "Oauth2" however this option does not appear for me and all relevant responses on here are in regards to microsoft accounts whilst my account is from a custom domain. Any help would be appreciated as it is a great inconvenience to not have access to my email.

I am using Thunderbird with an IMAP account. My quota for my inbox, as indicated in the lower right, is 98%. If I log in to my provider's webmail the quota stated is 2%. How do I fix this mismatch?

I have relatively few emails in my Inbox, Sent, Trash, Draft etc folders. Deleted folder has been emptied. Folders have been compacted a number of times. Thunderbird has been closed and reopened. I have checked with my provider, names.co.uk, and they confirm that my current usage is 2%. They pin the blame on Thunderbird.

I have searched online and whilst this does appear to be a fairly common problem, I have not found a solution.

I have tried moving all but the few latest emails to Local Folder, going through the usual deletion, empty deleted, compact folders, restart etc. and can only lower the percentage a small amount in Thunderbird, and it soon rises again to 98%. And it's very inconvenient not to have recent emails still in my Inbox.

Can anybody help with a solution, please?

Hello,

Im struggling with adding second email account in the freshly downloaded Thunderbird on new PC. I tested on multiple PCs and the errors keeps repeating. It says the login information are incorrect but I know for sure they are correct. Exchange auth error it says. After multiple login tries the app just freezes and stop responding.

The first email account added is working fine. Thunderbird version 144.0.1. Windows 11

Hi; I've signed up for the vpn, several times, but nothing appears. I don't see any box on the top right of any bar. I don't even know the symbol, but have checked all that are there. How do I turn it on? I found something about "privacy windows" but that just leads back to the signup page. I know it'll be simple, but I'm missing it totally.

I have been using Thunderbird for a number of years now and found it very good , but at the moment I have a problem, As an example when I clic on an e bay account to open and send feedback it won't open just shows an oblong when square boxes corners and centre.
