Thunderbird Support Forum

We have been trying to repair the sent folder in Thunderbird without success. Messages do not get saved there. Several recently have ended threads an said there is no support for email but that seems to be confused? In any case it loos like there is no simple fix to get the sent folder back. Do you think it would solve the issue to uninstall Thunderbird and install it again? Thank you for the help.

My Thunderbird email on my PC will only open intermittently in the last few days. Re-starting my computer sometimes helps, but only temporarily. There are no error messages- just nothing happens. I am still able to access email on other devices - just not on PC - which I use a lot. I'd be grateful for ideas of how to fix this. Thank you, Pam Rycroft

I am trying to set up my Yahoo account with Thunderbird. I enter the email ad password and nothing happens. There are no popups. Just the checking password. I also tried generating an app password from yahoo and using it and it didn't work either

Buonasera, stamattina non funzionando le mail in arrivo in Thundebird, ho riparato la cartella a seguito di un messaggio arrivato dal vostro portale dove mi diceva: spazio archiviazione terminato. Effettuata la procedura i messaggi in entrata hanno iniziato a funzionare regolarmente ma mi sono accorto che tutte le mail nella cartella posta in arrivo erano prive di testo. Cosa può esser successo e se è possibile ripristinare, grazie mille per un vostra risposta. Vi lascio in allegato un'immagine come campione. Cordiali saluti, Gianfranco

using thunderbird, cannot send some emails- error message unablr to authenticate outgoing server (SMTP) mail.waitrose.com. I am receiving emails normally and can reply to sent emails.

Just recently, I am unable to send replies or attachments from my Thunderbird email. My service is Comcast and I have verified my outgoing server settings as directed by Comcast. I also tried turning off my Norton for outgoing mail, still having the issue. Last week emailed worked fine.

My hard drive had to be replaced and now I cannot recover my Thunderbird Email. Keeps asking for a password but won't accept it. Asks for password for "mobile.charter.net" I think I have totally screwed up all the settings in trying to find a solution. I checked with my internet provider but no help. Could someone please help a very senior and very frustrated Granny? Thanks in advance.

I have just installed the new 102 version of Thunderbird. It asked did I want to overwrite the old version, I said yes, now I have nothing in the way of informatioin or old emails. In am on a mac. Help I really hate the fact that I cannot talk to anybody live

SUDDENLY, Thunderbird won't allow me to blind copy to the people on my email list sent out from my aol email.

My SMPT set up is FINE; it has never changed. It has NOTHING to do with 'adding semicolons" between addresses; I have NEVER had to do that before; please don't suggest that now.

message: "Sending message failed. An error occurred while sending email. The mail server responded: error sending message for delivery..Please check message and try again."

It happens with 2, it happens with 10, it happens with 25 or 40 recipients.

Where did you hide attach and send in T-Bird? I have been using this e-mail program for years and have installed i t on numerous relatives computers. Now it doesn't work?????

I have tried everything I read in your "help" pages but no matter how I set up Thunderbird for Email I cannot get it to send. I recently had to purchase a new computer that has Windows 11. Is Thunderbird unable to work with Windows 11? I'm so frustrated at this point & need HELP. For your information the SMTP is set up as: description: [edited email from public] @skybeam.com Server Name: securemail.risebroadband.net Port: 465 (I've tried 587 but it doesn't make a difference) User: My Email Address Authentication: Normal Password Connection Security SSL/TLS

Note: I've checked Thunderbird & the passwords on both Incoming & Outgoing is correct.

I keep getting the above message. I looked up online and there are free apps to fix same but I am worried some of these apps may compromise my computer. Can you recommend a free app that is safe please? Thank you.

Since today, we experience an unusual problem in Mozila Thunderbird. The program ask for the password for the email that is already sign in. And if we enter the password, it ask for the password again. The error is "login to server outlook.office365.com with username failed". Our company need to solve this problem because we use Mozila Thunderbird for over 100 employee.

Thank you!
