Thunderbird Community Forum

Titles of new emails appear in Inbox. Cannot open them. This problem only appeared as of today. Strangely, the last one, the code sent by Mozilla to create my account, opened normally.

Thunderbird will not let me access my email inbox without a password., I have windows 10, I have a new Mozilla password and a new Recovery Key code. My email goes through yahoo.com. The request I get is L0gin to my account failed. "Login in server imap.mail.yahoo.com with username martyhhtexas@att.net failed." I been trying to correct for over a month and I'm completely baffled on how to get access to my email through Thunderbird. I've used Thunderbird as my only source of email for around 2 decades . can anyone help me. I can access my emails through Yahoo.com but its a hassle, I miss my Thunderbird, Frustrated HELP......

On attempting to forward or even send emails, I get the following pop up message on trying to send. Some years ago I had an Outlook email address on Thunderbird but removed it. At that time, sending or forwarding emails wasn't affected and wasn't until recently.I still receive emails ok. The message is as follows: 'Sending of the message failed. An error occurred while sending mail. The mail server responded: This email was not sent but there is a way to fix it. To resend successfully you need to update your email settings (e.g. Outlook) to turn SMTP authentication on. For guidance on how to do this please visit: https://www.telstra.com.au/support/email/unauthenticated-traffic-limit Reference: OB315 e{9f3c547a-93d4-4f7f-9f1d-14b2a88679e7}. Please verify that your email address is correct in your account settings and try again.' I can't really understand the message. Can someone help me out with this issue? Yours etc, Richard

I can't understand how to get it to work when I get the emails from the online account and they are in Thunderbird, if I go into Thunderbird they are visible to anyone who would go in! Even if the person does not know my email password, they can just cancel out of the password box and all the emails stored on computer are available!

Also, I read some online post saying that Thunderbird does not store the emails in any encrypted way on the computer!

Multiple people can use a computer, or the user may be wary of whatever kind of access somehow, simply want it secured.

Is there no way for Thunderbird to do this after so many years? An extension or anything? I want to back up email account from online account, store on computer in secure private way but this program seems against that!?

A new Thunderbird icon appeared on my Windows desktop. I unpinned the icon in the bottom pop up bar, and dragged the new icon to the bar. When I clicked on the icon, Thunderbird ran me through a new account set up routine, and when I got through that, all of the local folders - in which I had stored a virtual library of emails from different sources that I use for reference and education - had disappeared. No, I do not have a current backup of the folders... Is there some other way to retrieve these, or are they simply gone forever? Thanks for your input, Jeff

After updating Windows 11 machine to Thunderbird Nebula, I am asked for a password when trying to subscribe a public nextcloud network calendar. I have installed this same calendar dozens of times on our school staff's desktops, so I know how to do it. I am pretty sure the upgrade broke it.

My desktop lost power, I went to restart and opened Thunderbird. I think it went to an updated version. The usual page that I had to confirm and enter password were not there, at least I didn't see it anyway. I noticed a tab for "create new account". So I did that, which it opened all new emails, but my old ones were gone and I don't have any of them saved to a folder. Is there a way to migrate the old emails to the new account? Thanks in advance

On my email account - keith@mediafivecorp.com - sometimes ALL my SENT emails are shown, but at other times only a about 15 or 20 show up...and from a wide range of past years. How can I get ALL my sent emails to show up all the time? Thanks.bold text

Having just installed the new update 128.0.1esr on two different computers running on Windows 10, we have the new problem that when composing new emails the text does not wrap to the window.

Changing the message format (Automatic, plain, HTML) does not make any difference.

Changing the wrap length to 0 in the Config editor does not make any difference either.

This is actually a real nuisance of a problem and we'd be very grateful for help. I suspect this is a bug in the new update but in until it gets sorted out we basically are going to go mad trying to write our emails. Is it possible to revert to the earlier version of Thunderbird, and if so, how?

Many thanks for any suggestions.

Hi, This is a problem that has been occurring with Thunderbird for a while now. I thought I'd previously found lots of posts on this topic and I wanted to check them but I can't see to find them now. I use Thunderbird for my work email account. I receive invitations to Teams meetings through email. When I use Outlook on my phone I can see an attached .ics file. When I use the web based email client provided by my ISP I can see an attached .ics file. When I use Thunderbird there's a message that says: "No writable calendars are configured for invitations, please check the calendar properties." and it claims there are no attachments. I don't care if it can't find a writable calendar, I want to download the .ics file. Where is the .ics file? I can download it from the other two clients and then import it into Thunderbird calendar fine. But that's a complete pain in the neck, having to log into a seperate email client to do that. If it's attached file, as the other two clients treat it as, why won't Thunderbird let me download it? Windows 10 Thunderbird 115.13.0 (64-bit)

I am disappointed with the update since I do not get an email preview when the email arrives when the sound goes off and the background color has changed from blue to brown. I looked around to get those changed but could not find a way.

When I open Thunderbird, I get the message:

The STAT command did not succeed. Error getting message number and sizes. Mail server pop.gmail.com responded: [AUTH] Invalid credentials.

I cannot get any mail from the server.

Hi My PC recently died and I am now trying to setup a new one. Firefox is fine but Thunderbird won't accept my password. I also had a Mozilla support login which I am using to send this message.

I have been using your programs for many years ans wish to continue. How can I get my correct TB password?

Many thanks Geoff Bell

Ever since the Airport computers got their Blue Screen of Death, I have been getting continuous Pop Up from https://tsdtocl.com/. It is only occurring on my Yahoo.com email account currently. This Pop Up has stopped downloads from my Yahoo emails showing "pop.mail.yahoo.com" could not connect. I see no email associated with the Pop Up in Thunderbird. The Pop Up is asking for me to Sign In using my Yahoo account. I expect a Scam since the Pop Up will reappear when closed. Any suggestions to get rid of this Pop Up?

Hello again! I asked this question a few weeks ago--and low and behold, the next day, my sent mails were being copied to my "sent" folder. But several never appeared. Now this is happening again--sent mails are not being copied to the "Sent" folder although I have that checked in setting--and it's very annoying! I see a small arrow to the left of a message I answered, but it's very important for me to have a record of all my correspondence. And without the copy I feel unsure that it was actually sent? Why is this happening? What should I do to get my sent emails copied to my "sent" folder ?? Thanks. Best, Nancy
