Thunderbird Support Forum

for about a month now I have not been able to download mail on Thunderbird for the Gmail account Configuration: imap.gmail.com port 993 SSL/TLS Oauth2 I have double authentication, the confirmation request appears on my smartphone, I confirm, insert the password on Thunderbird, accept the conditions and get the error. I also tried to change the password (on Firefox and Chrome I log in regularly, on smartphones too), with Thunderbird 102.13.0 32 bit on windows 11 no.... Below are the screenshots

How can I remove donation POPUPS. I installed Thunderbird a few weeks ago. Because of the excellent working mailbox, I immediately transferred a donation and then received a friendly confirmation, but still those annoying POPUPS.

I have not received emails addressed to the three accounts we originally set up years ago. The only email that has come through is one from xfinity which uses the xfinity account name. I logged onto xfinity and no new messages are residing there. I've downloaded a couple of the Mozilla help articles but don't seem to be getting anywhere.

My version of Thunderbird is 102.0.3(64-bit). It will not update. i keep getting a message that it is not able to download the update and need to download a new version for the update. Can any one help me. Thanks

Error message: "Sending of the message failed. The Outgoing server (SMTP) smtp.frontier.com does not support the selected authentication method. Please change the 'Authentication method' in 'Account Settings | Outgoing Server (SMTP)'." Can you help? Was on the phone with Frontier for an hour - they say incoming settings are correct (no problem receiving emails), as well as outgoing. We tested sending an outgoing message from their webmail server, which was successful. Thanks, dbleagle

I was told to reboot my system to complete a Thunderbird update.

After the system came up, my main email account wouldn't display. It was there when I went into account setting but wouldn't show. After closing an opening Tbird several times it showed up. now none pf my filters are running. In some cases it says the folder doesn't exist when it does! Most of the rules are missing actions!

What's up guys???

I am downloading emails from the web but they won't open. I have 3 in inbox for doxatmj@dircon.co.uk and 1 in muhuhu@dircon.co.uk - can't "Get Messages". Please help something has happened. Kind regards, Jane Doxat-Pratt

I have started to have emails disappear from my in box. I have been in touch with my internet provider with no luck as they think it may be some thing with in your system. I am not what you would call computer literate so I have no idea what is going on. Any help will be gratefully received Regards Geoff Chatfield

Just yesterday, I tried to download my latest email with "get messages" on my PC but got a message saying "error with account stanmalette" and "Sending of username did not succeed. Mail server pop.embarqmail.com responded: stanmalette is an invalid mailbox.Account name should be the fully qualified email address". I can still get my thunderbird email on my phone, but the PC seems locked as of 10/24/22. Should I set up the account again, or download Thunderbird again, and should I be pop or imap? I have been using Thunderbird for many years and this was unexpected and confusing. Stan

I have an Outlook email account which I manage using Thunderbird.

For reasons not known to me some strange folders have appeared in the folder list. The folders in question all have italian names and appear to be some sort of system error folders - Problemi di sincronizzazione.

I do not recognise them, they are empty and are not visible when I view the outlook account using a browser.

I would like to delete them but when I attempt to do so I get an error message "The current command did not succeed. The mail server for account Outlook responded:Command Argument Error. 11."

Any help to get rid of them would be greatly appreciated. Thanks In Advance

Email attachment icon is small dot with two curved brackets on each side, no paper clip. Clicking on it only offers option to download for offline use. Cannot find download after, not in download file. Cannot open attachments at all. Something changed, not sure what.

I cannot send emails from Thunderbird. I am using MS Windows 10 and my ISP is comcast.net. My email provider uses MS’s Outlook servers. For years I had no trouble using Thunderbird. Even after my email provider switched to using Microsoft’s Outlook servers. But when I subscribed to Microsoft’s Office365 and accidentally opened its Outlook module/application I was no longer able to send out emails. I could of course receive and send emails when I logged into the web version of Outlook, but while I could still receive emails I could no longer send them via Thunderbird. When I installed the latest version of Thunderbird (78.14.0 (32-bit)) I was no longer able to even receive emails. However, when I set up a “new” account (and used the email provider given password, which works at the web version of Outlook) and switched from POP3 to IMAP I was able to receive emails again, but I am still unable to send emails. I have tried numerous settings for my Outgoing Server (SMTP). None have worked. So my questions are: 1. What are the appropriate SMTP settings? I’ve tried so many, so I’m not providing the current ones. I’d like to start with a clean slate! 2. Are there any settings elsewhere that I need to tweak? 3. Why can’t I see (and alter if necessary) my password in my settings? (I assume they are still the appropriate ones that I inserted when I set up my account again.) However, even when I manually insert them after an error message and a form asking for my password they do not work. I’ve tried it with my antivirus and firewall protections (Webroot & Windows) turned off. SC

I had a large number of e-mails in two separate accounts and all of a sudden, they were gone and I had only a few from today. What happened? I need them for records and such.
