My house was hit by a lightning strike and it blew out my computer. It looks like both the drives in that computer are readable. So I am wondering how I can get all my email back into thunderbird. It was a pop account. All email was saved to computer. I'm using windows 10. I tried to just copy the old file at Users/Mike/AppData/Roaming but that didn't work. It didn't bring back all of the folders. Please let me know if there's anyway to rebuild all the folders and emails. Thanks in advance for your help. Mike

My COX email was transferred to Yahoo a few months ago. I followed the procedure outlined by COX and changed over to Thunderbird as I had used before. Everything worked great until the morning of August 18. I cannot receive or send email. I have tried contacting Yahoo who will not help me unless I subscribe to their Premium Technology package. I would really like to talk with someone from Thunderbird but have not found any help. HELP I cannot receive or send email

I saw a post about creating a calendar event directly from email ([https://support.mozilla.org/en-US/que.../1091761]) and it mentioned using

Right Click-Convert To-Event or Task

However, I do not see that option. The post is archived so I cannot followup with the original posting.

When I Reply the cursor used to default to the text so I could just start typing my message.

Now it defaults to the address field. How can I go into the hidden settings to change it?

Tried installing v115 latest on Ubuntu. Hangs when I try to set up email acc and it tries to log into the Gmail server. "Danger ahead" displayed on page with no option to force it to proceed.

Thus please dispense with any solutions for this and just inform how I can install v91.1.2 using apt-get

I see you list the versions but I see no where on how to specify which version to install.

Cox just transferred all customers' email systems to Yahoo. After my e-mails were transferred to Yahoo, Yahoo tried to help me when I was getting error messages saying that log in to server smtp.mail.yahoo.com with my user name (my e-mail address) failed. The Yahoo rep told me that my problem is that "Whenever the generated app password from Yahoo is entered, sending emails works, but it only stays like that until the computer gets restarted. The app password is not saved." The rep told me that many Thunderbird users who had their email systems transferred to Yahoo are having the same problem. Has anyone had this problem and been able to resolve this problem? Thank you! Cyd

setting up a new computer, trying to set up my gmail account on Thunderbird I get this message... Secure connection failed

' live.mozillamessaging.com uses an invalid security certificate.

The certificate is not trusted because the issuer certificate has expired.

(Error code: sec_error_expired_issuer_certificate)

   *   This could be a problem with the server's configuration, or it could be
     someone trying to impersonate the server.

   *   If you have connected to this server successfully in the past, the error may
     be temporary, and you can try again later.

  Or you can add an exception…

I have 2 machines side by side, the old works just fine , its 12 yrs old, i want to use my new one... how do I fix this ?? And yes ive tried manual settings and all that.. its the certificate in Thunderbird thats expired it says

Win 10 user and very frustrated with Mozilla Tbird. Have tried many help screens to add a second email address to Mozilla Thunderbird but all are rejected. Used your tutorials, you-tube guidance, etc and nothing works. What do I need to do to register a second email for other personal business? Should I register with Google first?

I installed "cardbook" (from gitlab) and wanted to print the address list, entry for entry. How do I do that? This is not a generic TBD question. but perhaps somebody knows ...

On my new T-bird installation, I cannot find a way to add Send-Receive as a customization of the toolbar area, nor do I find so far any other way to send-receive, aside from interval-based automatic sending and receiving, and of course composing and sending a new email. Em-client has an easily accessed send-receive button, as does my long-time Outlook desktop client.

I recently installed Linux Mint on a separate SSD on my Win10 PC and have now a dual boot environment.

Linux can access (r/w) all windows drives.

It should be possible via TB profile manager to access the TB profile on the windows partition.

My question: Are there any known incompatibilities between TB on Linux and Windows ? I don't want to end up having problems with the Windows installation of TB when trying to set this up.

I needed to change my gmail password. I went to Saved Passwords and changed the password on the account--I id'd the account by old password. However, I'm still getting the error message: The STAT command did not succeed. Error getting message number and sizes. Mail server pop.gmail.com responded: [AUTH] Invalid credentials.

The account was not an oauth account which has a password I don't recognize. Also, the associate smtp record has a different password.

How do I change the password? Do I need to change the smtp password also?

thanks carol

I have been struggling with this for months. I really like Thunderbird but I have tried everything. Receiving emails works fine, it is just the SMTP that hangs. I will have to abandon this and go to outlook if I cant resolve. It Does eventually go but it takes a couple tries. The examples given, I resent and it was fine.
