I have a new PC. After installing Thunderbird onto my new PC, emails from my old PC are not there. Can these be recovered? I have a copy of my old PC hard drive files but not the actual PC. Thanks Jim Ferrier

I sent an email with multiple BCCs and no CCs or TOs, I put myself as one of the BCCs.

I did not receive it and I do not think anybody else did as well since I asked a few people.

The email is in the sent folder. I tried forwarding the email from my sent folder to myself as CC, and that worked. I also tried fowarding as BCC, and that worked.

So what is going on? Is BCC working? How can I know for certain? Do I need to foward the email as BCCs to all my BCCs to get this to work?

Thanks for your help.

""Description: COX Server Name: smtp.mail.yahoo.com Port: 465 Connection Security: SSL/TLS Authentication method: OAuth2 User Name: your user name, duh - Mine keeps changing the user name to the last name I put into any of my 6 accounts. The only way it will send mail is if the correct user name is in the correct account (obviously). Why is it changing constantly? click OK""

I've read the "fixes" from 2023 and they do not work for me. I tried changing the DESCRIPTION to blank, didn't work. Changed them to the corresponding e-mail for the account. Didn't work. Changed it to "SMTP" with the corresponding e-mail. Didn't work.

It keeps changing the last one I edit to the one I edited before it. It's driving me crazy. Won't send mail unless the User Name is correct (obv.)

Whole mess started when forced to switch from Cox to Yahoo recently. Seems to be working other than TB changing the name as soon as I type in the next one in the next email address and then it not working until I change the User Name back to the proper e-mail address of the 6 accounts.

I know i have asked this already but i did not receive an answer of a solution and id really like someone to help me with this. It is a duplicate question but again no answer and id really like one . i want to remove it please do not tell me toget a new profile and lose everything i have. there has to be another way

I have 4 e-mail accounts in TB, and I want to switch from the current default account to another. But how do I do that. I cannot see any button, place where to do that in the settings. Why the heck does TB needs to be so tricky to deal with, compared to Outlook?

Support needs to take their head out of the sand! With the latest release of Thunderbird for iOS it does not work when trying to type a message. The default is "preformat" and trying to change it to paragraph or other does not work. Older version works on my MacBook Pro (2011). My MacBook Air, Thunderbird writing message does not work. Glad I did not contribute money! Oh well must be a way to get folks to purchase Office 365, Outlook?

Could not find anything in add-ons, settings, or about:config. There is a topic on this site https://support.mozilla.org/en-US/questions/1086884 but I am not able to follow it because there is no add-on or plugin to enable or I cannot find it.

I just migrated my email from cox to yahoo servers. The cox.net domain is retained.

I had never seen a "bulk" folder with my other domains and was having problems with emails being sent there.

I deleted the bulk folder and it moved to trash but cannot actually be deleted. I also re created a bulk folder. see pic.

Now emails are still going to the bulk folder that is in trash.

Is there any way to fix this?

Thanks

I am trying to do a mass mailing in Thunderbird to about 2015 libraries, with another one to come. I followed all the instructions carefully and generated all the messages and they went into my outbox, with a "send later" command. Then this morning I entered the command to empty the outbox. I immediately began getting an error message that I could only send 50 messages an hour. Feeling like the sorcerer's apprentice, I closed thunderbird, whcih stopped the bleeding. Now I have 1350 messages in the outbox which thunderbird did not try to send.

Fixing up this mess is going to be complicated, particularly with respect to the messages it did try and fail to send (about 750 of them.) But I could make some real progress if I could figure out how to send 50 of the unset messages at a time from the outbox. I have the first 50 out of the 1350 selected right now, but I can't figure out how to get them sent. HELP! Thanks in advance.

I was subscribed to a large distribution list, but then unsubscribed. But I didn't unsubscribe. So I subscribed again, but was soon unsubscribed again! My email address and password may have been hacked. So I logged into my Comcast ISP and changed my email password. Then I started Thunderbird, and as expected, it asked for my password, and I gave it. My email came up. I tried sending an email and it asked for a sending password. I ignored it, but after a long delay, it refused to send the message. So I tried again, this time giving it my new email password. The sending then worked. I assumed all was now OK.

But, as a final test, I exited Thunderbird, and then restarted. It again came up OK with my emails shown. Then I again tried sending a test message to myself. But it again asked for my sending password! Thinking this might be a scam, I put in a password of "bullshit". Then I received the following popup message:

Sending of the message failed. An error occurred while sending mail. The mail server responded: Polite people say HELO first. Please verify that your email address is correct in your account settings and try again.

What!!! It sure seems like someone (at Thunderbird?) is in the loop grabbing my password before encoding it for storage. A similar thing happened in the past, where I think my account was hacked. So, was this a hacking attempt, and if so, was it from Thunderbird software or my Comcast ISP?

I need to set up several gmail accounts in Thunderbird. The accounts exist; I can see email by going to gmail's webmail for them. I'm running Thunderbird 115.10.1 on Windows 11.

I choose Tools > Account Settings > Add Mail Account then provide the name, email address, password, then TB validates the credentials with gmail's systems. I get a green light message saying that gmail found the entries. I then provide the appropriate POP3 server name and port address and the appropriate SMTP server name and port address and confirm security settings - all of which were verified and carefully edited when entered. TB then sends the information to google and after an very long delay returns a message saying the attempt failed, probably due to incorrect password or settings. All of the information and settings - including the password which was copied and pasted AND the same one used to log in to gmail webmail - are correct.

Obviously, I'm doing something wrong but don't know what. The error message is so generic as to be unhelpful.

Can anyone help me discover the problem?

Hello, since upgrading to 115 Thunderbird has disabled all add-ons, and does not have an option to reenable them. This was done to several extensions which are not marked as incompatible including "NestedQuote Remover" and "Unmangle Outlook Safelinks". Removing and uninstalling them solves nothing. Indeed, the button to install from the market does not work. I had to save to and then install from a local file to test this.

I am not in trouble-shooting mode, but I have found that "Load Temporary Add-on" in debugging works for the current session.

(I tried searching Google and this forum to no avail.... only turning up irrelevant thread about older versions, Firefox etc.)

I am having issues with Thunderbird not retaining my email server and passwords. Each time I want to send an email, it prompts me for the password and then tells me that the email address and server don't match. I have tried numerous times to correct this, but it doesn't hold the information. It also switches the server info between accounts. I have 3 different email account and sometimes only one works correctly

I'm attempting to import/load an Archive.sbd file folder containing my old Thunderbird emails circa 2002-06. I attach an image showing the files and their sizes. I'm using the import tool and selecting import from a thunderbird profile and selecting all categories of Data to be imported. I get an import failed unexpectedly message. I attach an image showing this response. If I select only mail messages to import, the process completes with a file folder called Thunderbird Import which is empty. Not sure what the problem may be. Possibly exceeding file size? or Am I selecting the right category under import. I have no Zip files hence didn't use import from a file. I'm really unsure as to how to even look at what's on the Archive files but certain the larger files contain email messages.

Thanks,

Dzień dobry, Chciałbym uzyskać pomoc z odblokowaniem możliwości wysyłania wiadomości, mianowicie prowadzę restauracje i wysyłałem duza liczbę wiadomości z ofertą gastronomiczna i nagle pojawił się problem.

Profiles was bad enough, as Thunderbird can never open the zip file (the wording of the alternative method is gobbledegook, and there are no recognisable files if you attempt to decipher it). At least you can set all your email addresses up manually - you can't physically re-types five years of calendar entries. The infuriating this is that when you start the import, the calendar entries appear before your eyes for up to five seconds and then the program crashes ... again and again and again. I must have been trying this on and off for years now and still nobody has fixed it.

I created a signature years ago. With the last Thunderbird update, the signature font (and image) shrunk in size. I would like the signature to match the font size of the message text, like it used to. I can't find any information about that, or any explanation as to why it shrunk.
