Thunderbird Support Forum

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

Greetings,

In Thunderbird 115.12.2 (64-bit) on Linux Debian 12.6, when I examine "Help -> About", cursor movement in the focused information window moves the list of messages displayed underneath in the unfocused messages window. Hopefully the image suggests the issue. Is this an OS problem or something that can be corrected in Thunderbird?

Also, I maintain several accounts, each with several folders. It would be helpful if these all stayed collapsed until selected, with a digit alongside indicating the number of unread messages in each, but recently they each seem to fully expand at inopportune times, making email management rather difficult.

Is this the result of a selectable setting somewhere, please?

When I start a email message search, I am bombarded with bad suggestions for email addresses. These include addresses from everyone I've received email from even though I have deleted these entries in collected email addresses and my personal address book.

The addresses could be from old purchases or ebay responses or anyone I've ever received an email from. I have deleted most of the emails entirely, yet I still get all these bad addresses when I search.

Is there a way to clear the history in search or remove the email addresses where I have deleted the email?

I've attached a Home Depot search as an example.

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.

Hi, I’m trying to move from Outlook 2003 to Thunderbird 115.12.2 (64-bit). Using the import wizard fails. Tools > Import select Import From Outlook and the following message appears. “Either there is no default mail client or the current mail client can not fulfil the message request”. I’m taken back to the Import from screen with the addition of a red panel with “No Profile Found” on it. Outlook 2003 is the default e-mail client, checked more than once. I’m trying to migrate to thunderbird so I have no account setting, thinking they would be imported. My pst’s files have been moved to a directory on a different partition to the Outlook programme, tried creating a dummy profile using default Outlook storage and still fails. I’ve looked at converting pst files to mbox, but this doesn’t see to include the account settings. But I could add them manually or I can not import the mbox files or directory structure into Thunderbird. I’ve been messing around trying other things but nothing works. Internet searches, Thunderbird forum searches suggests solutions but all fails and the steps don’t match Thunderbird menu, etc in many cases. I’m stuck. Can anyone give any advice on how to migrate from Outlook 2003 to Thunderbird. Tools, Add-Ins or manual methods, anything just to get me up and running. PS I’ve two pst files, one is the default main Outlook.pst and the second a secondary store I created in the folders of Outlokk called Store.pst, beside the none default storage location everything else is standard for Outlook and Thunderbird.

Microsoft is changing the authentication method for outlook mail to OAuth2. I follow the guide provided to update Thunderbird, but my version of the program does not have OAuth2 as an option. My outgoing server is smtp-mail.outlook.com, but OAuth2 is not an option in the dropdown for authentication method.

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

A couple of days ago I had to change my default browser from Firefox to Chrome to fix a problem on a particular company's web site. After I made Firefox the default browser again I found that every hyperlink in an email or a document that I clicked on opened Firefox at the same web page: "https://read.amazon.com/landing".

I have no idea what I might have done to create this situation, let alone how to undo it.

I am using Linux Mint with Firefox, Thunderbird and Libre Office.

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?

I have a custom domain (me@mydomain.com) with email / contacts / calendar hosted by Google Workspace. I initially managed to add both the email and calendar account to Thunderbird but recently the calendar stopped syncing.

I tried to fix the problem by first removing the calendar account. This did not work because the 'Create New Calendar' -> 'On the Network' account wizard does not prompt me for the Google OAuth2 login page but just asks me for a password and fails. I tried to supply several 'Location:' URLs like gmail.com, calendar/accounts.google.com but none lead to the Google OAuth2 page.

Finally I removed the email account too and re-added it. During the new account setup workflow Thunderbird seems to look for calendars too but failed to find any...

How do I proceed? How are you supposed to set up a Google Calendar on a custom domain using the OAuth2 sign-in procedure?

IF I SEND AN EMAIL TO MYSELF, JUST ONE WORD AS A TEST, I HIT "SEND", AND IT IMMEDIATELY GOES AND ARRIVES, AS PER NORMAL. FINE. IF I SEND EXACTLY THE SAME ONE WORD EMAIL TEST TO, FOR EXAMPLE, MY WIFE, OR ANY OTHER INDIVIDUAL RECIEPIENT, IT TAKES A LONG TIME TO EVEN SEND. I GET A PROGRESS BAR AS IF I WAS SENDING A LARGE RAW FILE OR SOMESUCH. LIKEWISE IF I SEND THE EMAIL TO ME AND CC IT TO ONE OTHER PERSON IT TAKES AGES TO SEND. ONLY AN EMAIL TO MYSSELF ALONE WORKS AT THE USUAL SPEED. MY BROADBAND SPEED IS FINE. I HAVE USED THUNDERBIRD FOR YEARS ON DIFFERENT LAPTOPS AND DIFFERENT COMPUTERS WITHOUT THIS ISSUE. I DO NOT KNOW WHAT TO DO, CAN YOU HELP?

I would like messages I identify as junk, or messages automatically identified as junk, go to the spam or junk folder. All junk messages remain the main inbox.

On the other hand, in my "spam" folder are many emails that have gotten sent there automatically, but none of them are identify as spam (by the fire symbol being lit up).

In settings, I have "junk settings, box check on new junk messages to:, other, spam.

I also tried box check on new junk messages to:, Junk folder on:

When checking my email the 'Thunderbird' status bar says "downloading message' (as normal), but sometimes the message does not appear in my Inbox or any folder.

I'm using Thunderbird 115.12.0 on Linux Ubuntu. The email is downloaded via the POP protocol.

I have checked on the server and nothing is left there.

Using the Thunderbird search function on 'date' only, the e-mails actually in the inbox or folders show up, not the one purported to have been downloaded.

All of my folders are set to 'Unthreaded'.

Any ideas please?

Hi, Any time I'am connecting to email addresses ending by @akeonet.com (SFR compagny) on THUNDERBIRD, I'm receiving a message asking me my password imap.sfr.fr. Same to send a message exit server (STMP) smtp.sfr.fr.

Problem is the existing password is not working anymore with THUNDERBIRD but is still working with the webmail of SFR ????

I'am don't have such problem with addresses ending by @gmail !!!!!

Can you help to reconnect THUNDERBIRD to server SFR/ Neuf ?

Thank you to help me to solve the problem.

as stated in the title, my HDD failed the other day and on recovery, my Thunderbird seems to have failed too.

I know (sort of) that it is all driven by the Profile.ini file.

But everytime I relaunch TB (even after what I think is an uninstall and a reinstall) I am getting : "Your Thunderbird profile cannot be loaded. It may be missing or inaccessible."

I would be happy enough to have a blank TB load up and I would reconfigure my various email accounts. but I cannot seem to do even that.

I know there is a trick to getting to a Thunderbird configurator....but I have forgotten what it is.

Where does TB "look" when it starts up? how would I control that?

Hello! I'm trying to subscribe to the calendar at this link: webcal://github.com/othyn/go-calendar/releases/latest/download/gocal__community_day.ics

But when I add the calendar to Thunderbird using New Calendar... > On The Network, it resolves that URL to this very long different URL: https://objects.githubusercontent.com/github-production-release-asset-2e65be/580172601/b8d41b00-ad34-4a4f-937b-55ab6a554213?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=releaseassetproduction%2F20240625%2Fus-east-1%2Fs3%2Faws4_request&X-Amz-Date=20240625T114538Z&X-Amz-Expires=300&X-Amz-Signature=10a1c88bd26110f81b16dd6f839ce758de482cc6c450135e518550bb3eed5840&X-Amz-SignedHeaders=host&actor_id=0&key_id=0&repo_id=580172601&response-content-disposition=attachment%3B%20filename%3Dgocal__pokemon_spotlight_hour.ics&response-content-type=application%2Foctet-stream

The resulting calendar then works for one day but then disables itself and cannot be re-enabled (if I try to enable the calendar, it immediately disables itself again). I think this is happening because the calendar at the webcal link updates to a new file every day, so the specific link that Thunderbird resolves to becomes invalid on a daily basis. Other calendar applications that I use (like the iOS calendar app and the web interface for mailbox.org) do not resolve the link (they just leave it as webcal://github.com/othyn/go-calendar/releases/latest/download/gocal__community_day.ics) and they work fine, which is why I think the link resolution is causing the issue.

Is there a way to get this type of webcal link to work with Thunderbird?

I also filed a bug report here https://bugzilla.mozilla.org/show_bug.cgi?id=1906077

Having followed the instructions at https://support.microsoft.com/en-gb/office/modern-authentication-methods-now-needed-to-continue-syncing-outlook-email-in-non-microsoft-email-apps-c5d65390-9676-4763-b41f-d7986499a90d to update the security settings on my outlook/hotmail email accounts Thunderbird no longer reliably saves/enters the passwords. The password is saved in settings as that is where I copy it from to enter manually but why is Thunderbird not doing the entry as previously. It is not every log in and not always the same account, but regularly one or the other will come up with "enter your credentials" Also occasionally the credentials screen will flash on screen and then disappear, not necessarily for the account I am using at the time but one of the others. Any help appreciated Thanks Paul

When I am trying to access emails, a popup says to get certificate= imap.aussiebroadband.com.au:993 and confirm security exception. It will not allow emails to download

keep getting "Login to server imap.mail.yahoo.com failed." I've tried everything thru Mozilla to change passwords and tried every password possible. It's been 2 weeks no access to my emails thru Thunderbird. I'm at a loss. what can I do to get into my Thunderbird account without dumpig it all to start over?
