Hi, I am hoping to have two thunderbird downloads/accounts on the same computer.

ie can I run 2 separate thunderbird portals -

one for my talktalk emails

and a completely separate one for my gmail/google accounts.

I know I would be able to load the gmail/google onto my original Thunderbird account (but I would like to keep them completely unconnected)

Thanks in anticipation, HM

Is there a way to remove the "read" message bar at the top of the mail. It shows all the messages you have read, so I don't have to keep deleting them. I've looked all over and can't find anything about it. TIA Linda

Since my husbands departure, I have had the hardest time trying to access my husbands accounts. Luckily we have recovered many, but one of the most important ones is his thunderbird account. He is due to receive important information that I as his wife am unable to access. Can someone please point me in the right direction. I can be reached at [edited @gmail.com ] Thank you for your time, Chun Walls

I've managed to migrate emails from Outlook 2007 to Thunderbird 115.12.2 (64-bit). Everything was going great until I marked the messages as read. Now, I can't see the messages. I don't want that. I want to be able to archive my emails in folders -- I have the disk space to do so. How do I get my emails to appear (Thunderbird shows email counts, just can't see the messages), and fix it so that I don't lose them again?

Dear Sir or Madam,

I have just migrated Thunderbird to my new CUBI desktop running Windows 11. I get security errors when I launch Thunderbird. My email provider The Messaging Company advised me to change server settings, which are now shown in the Troubleshooting Information page as account1 (pop3) pop.themessagingco.com.au:995 SSL/TLS Normal password smtp.themessagingco.com.au:587 STARTTLS Normal password true.

On launching Thunderbird I get the 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: <a id="errorCode" title="SEC_ERROR_EXPIRED_ISSUER_CERTIFICATE">SEC_ERROR_EXPIRED_ISSUER_CERTIFICATE</a>

   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…

AND when I attempt to send an email I get warning that the SMTP server does not have a valid certificate. If I ask, in either case, to "Get Certificate" the response is that the site attempts to identify itself with invalid information.

I have "tried again later" over two weeks, and nothing has changed.

The Messaging Company is a fairly large email provider: it seems strange that its security is incomplete. However, I am not happy to just set an exception and over-ride these errors without doing all I can to check that there is not something screwy going on. I really value using Thunderbird, and The Messaging Company's advice that I should just use webmail is not at all satisfactory: I keep everything on my computer or backed up to a portable drive here.

Please: is there anything I can do or should know to fix this problem?

Best Regards, Margaret Mackisack

Why is it that Firefox can sync links and other setting across all versions, in all locations and yet Thunderbird can't even sync address books, history and filters? My only solution is to only run Thunderbird from a flash drive I have with me all of the time. It's not ideal but it works. Dave out

P.S. It also aggravates me that I have to use OWL with exchange server, which I dislike very strongly!

Thunderbird was not my default email app at POP3 installation, but anyway 900+ emails soon appeared in the Thunderbird inbox after my sign in for Outlook. My working assumption was that no emails would appear in an email app, unless that app was already the default app, which Thunderbird is not. The initial POP3 download is not under user control? Apparently not. But I don't think em-Client did this to me when testing it.

When I first installed thunderbird a couple of months ago I set it up for my vigin media and my google email addresses and it all worked fine. Then about a month ago it refused to send e-mails from my virgin media email address ( I can receive but not send). Virgin media said it was a password issue I had to use a third party e-mail address to log into my account and change the password. It has taken VM 3-4 weeks to create the new password for me.

However Thuderbirds does to recognies the new password. I removed the VM email address for Thunderbird and tried to reinstall it but I can't as it says the pass word is wrong. The new password works in outlook and in the google e-mail browser on my phone and tablet but not in thunderbird, so nothing wrong with the password.

I have read a blog from someone with a similar issue (except he could not receive emails from his VM address). He was recommended to create a new profile. I have done that and it still does not work.

 Any ideas anyone?

Something happened to my Thunderbird account on 6/15/24. I am not able to send or receive e-mails. I have attached 3 screen shots. One is showing at the bottom right of the screen that it times out and does not bring in any messages. Another shot shows settings for incoming and the other shot is showing settings for outgoing messages. Please help! I have tried to upload images of the screen shots taken and I get this error message. "Error uploading image

Invalid or no image received."

why does my hotmail in thunderbird sometimes get my emails and other times it says "Sending of password for user *********@hotmail.com did not succeed. Mail server pop-mail.outlook.com responded: Authentication failure: unknown user name or bad password"? Then it starts getting them again. It's totally random. Every once in a while it does it with my .live email too. Yet other .live and .hotmail addresses never have a problem? TIA

I am using Thunderbird version 115.12.2 on Windows 10 and have set up about 36 different calendars. To tidy up a bit, I would like to hide all calendars AT ONCE and in the next step show each (separate) calendar INDIVIDUALLY. ONLY: HOW do I hide all calendars at once? Possibly accessible via extensions / add-ons? Which extensions would be recommended? Thanks for all your help.

Issue began Monday 7/1 where Thunderbird would not receive new email from AOL. At times it would tell me to enter the password. But the p/w I entered was not correct so that made situation worse. Found "Saved Passwords" in Help->Settings where I was able to retrieve the -correct- p/w for one of the email addresses being actively used in Thunderbird and problem solved. When I went to find the correct p/w for the other email address, the account in "Saved Logins" was not there?? Was odd that the list did display email accounts I haven't used in years, but not the 2nd one that I use daily! I tried changing the p/w at AOL Mail, but that didn't work for either of my two accounts. Bottom line, why isn't lf82me@verizon.net showing up in the "Saved Passwords" in Settings?

Hello! Thunderbird has stopped downloading messages from my Yahoo+ account. I can send messages from it OK. When I try to get it to download, it says: Checking Inbox for new messages... and waits at this point. Then I get: Host Contacted, sending login information... Then it waits for a long time. Eventually, it indicates "No messages to download", and then goes back to "checking inbox for new messages". If I click "Get Messages", a pop-up comes up with: "Error with account... and below: The account fischer94563@yahoo.com is being processed. Please wait until processing is complete to get messages." I've deleted the APP and downloaded and installed a new copy. No changes. Deleted and reentered my password with Yahoo. I'm at a loss to understand why this is happening, but it was working fine until recently. Any thoughts? Thanks. Kevin

Since December last about every 30 days or so Outlook locks my account. This only happens when I "hit" send on an outgoing message from Thunderbird. A friend has suggested that Outlook sees my outgoing e-mails as spam and when it reaches a critical number Outlook locks my account. Attached is a screenshot of the error message. Has anyone else run into this problem and, if so, is there a solution? Thanks, Ken.

I'm using Thunderbird 115.10.1 and Windows 11 Pro. Thunderbird has suddenly started sending my partner's emails to Trash. We've been emailing fine for years before this. She has not changed anything in her emailing. I've closed and re-opened Thunderbird. Her emails are not marked as Spam and I have marked some of them as 'not junk'. Anyone got any ideas? I can't seem to find reference to other people having this problem.

I changed the email server in settings and all my stored emails are gone! Win10, Tbird 115.10.1. How do I get them back? Only one Email acct of three are stored on the server and those get downloaded to a different computer and then removed from the server.

Background: I was wondering why I didn't get any new emails for a few days and apparently GoDaddy migrated servers without telling me. So the settings there were screwed up as a result of a "~" instead of a "-" in the server name which the tech support guy changed. I was eventually able to access emails at my GD acct using their webmail.

But the server name changed so new emails weren't downloading to my computer. I went into Tbird settings and changed the SMTP servers to the new server address and now I don't have ANY of the old emails which I neglected to backup. ALL I did was to change the server address.

Is there a way to change/view/merge the T-bird user folders so I can access the old emails, folder and directory? Thanks, Bob

My send email button has dissapeared . I am unable to send any emails. Geek Squad has spent several hours trying to get my email send button back. They say there is a glitch in Thunderbird. Please fix it. My phone number is [edited phone# from public support forum]

Hi I am dying to convert my thunderbird email into a kanban board in thunderbird and then access the emails there as I need to work with them. This will allow to automatically see which emails are still to be done etc but in a very visual way instead of just scrolling through my email tags.

Does this exist and if so please how do I find it?

if it does not exist could the developers please kindly consider adding it into future thunderbirds?
