Thunderbird Support Forum

For the last week or so, I haven't been able to sync my emails to Thunderbird even though this is working fine for Outlook. Before a week ago it worked fine though.

I set up a new Windows 11 PC (64-bit) about 2 months ago, and installed Thunderbird Supernova. I allowed MTS to choose all the settings and everything was working fine until about 3 weeks ago I am now running version 115.11.1 (64-bit). I noticed that many messages I recieve at scheduled times every day were not appearing in my MTS message list until sevveral hours (a few actually took 3 days) after their normal delivery times. Checking with the senders revealed no change to the time they were sent. Looking at the messages when they appeared showed that they WERE received on time. Logging into the web interfaces for Gmail and Comcast/XFINITY email revealed that the messages were arriving on time. The only logical conclusion is that MTS has a problem in its IMAP protocol implementation that does not recognize new/unread messages as such, and therefore does not retrieve them. I am legally blind, and up to this point, mTS is the only fully accessible, easy-to-keyboard-navigate email program.

when i try to access my email i get the message LOGIN TO ACCOUNT FAILED. i found a page in this community which addressed this problem, but none of the suggestions solved the problem. it started 3 days ago. i can access my email online with FIREFOX, but when i tried with CHROME i could SEE the emails, but when i clicked on one, couldn't read it or do anything WITH it.

I like to keep a few email 'open' tabs available so I can remind myself of important tasks. It seems that the tabs all get discarded when there is an update. How can I keep them from being deleted by an update?

I Can't send or receive emails from Thunderbird, over 24 hours now. I get error message above and repeated requests to log on with my passwords, but my password doesn't work. I log onto and go to my AOL server to see my emails.

Hello! Since I couldn't find help in the forums, I will create a new question. For about a year now the PC at my work will not open mailto-links correctly. There is no account to select from, the subject has a lock-symbol. The receiver's address is correct though (I replaced it with "address" for the screenshot). This PC is the only one I know with that problem and only with external mailto-links. If I click on an email address inside a mail, it opens it correctly. Thunderbird version 115.11.1 (32-Bit), Win 10

It's pretty impractical, so I am hoping for help. Thank you!

I want that all my mail from all mine email boxes be restored to the original mail boxes. Now all the mail is removed there and that must not be done

How do I copy it back!!!!!

Any addon I use to open a tab with Google Chat, Keep, Calendar or Messages results in opening the Google Account Help page. Including apps that let you add links to Spaces. If I click the sign in button it just reloads the page. I have zero issues signing into those in my browser.

Thunderbird 115.11.1 (64-bit)

When I launch Thunderbird I get the following 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 Thunderbird then automatically downloads emails without asking me for a password. I have just migrated to a new desktop computer (MSI CUBI 5) and this started immediately.

When I try to send email I get a message telling me my outgoing server does not have a certificate, but this doesn't appear to be Thunderbird's problem?

I'm not happy about any of this? Can you advise me please where I should be directing my request for help? It doesn't seem like it should be a Thunderbird issue, but the address includes the word mozilla so I am sending it to you...

Thanks for any help you can offer, I really like (and support) your software. Margaret

Good morning. I have been unable to receive e-mails since 30/05/2024. Has the fact that I received an e-mail message from "Mail@voice" <mboudreaux@firmgroupagency.com> on 31/05/2024, got to do with the problem. I would be grateful could help solve the problem. Thank you. Emyr Davies.

Hello! I have linked my smartphone with the add-on: Provider for Google Calendar. How can I now transfer my existing appointments to the Google Calendar? I tried to export the existing appointments and then to import it into Google Calendar. Unfortunately, this was not possible because not a single appointment from the existing calendar is exported. I just get an empty .ics file. Any help? Please! Martin

I'm connecting to an MS Exchange server via smtp.office365.com and mostly this works OK by now. I do have a stupid problem, however: After deleting several folders, they always "come back" as "ghost folders" (grayed out and without messages) and it's impossible for me to get rid of them. Very annoying. I've tried a couple of steps:

• of course, I tried deleting the folders through the Thunderbird interface, also from Trash, where they first move to
• I also tried to delete msf-files associated with the deleted folders -- to no avail
• I also tried to unsubscribe from these folders using the "Subscribe" interface -- this is not possible: I can tick off the folders, save my choices, but as soon as I open "Subscribe" again, these folders are back
• I also tried to use Outlook, but the deleted folders are not shown in Outlook -- it seems to me that Thunderbird has difficulties letting them go

I'd be very thankful for any constructive help!

My Thunderbird profile in Linux Ubuntu 24.04 is in /home/dick/Thunderbird_mail/me. I want to copy it to a new directory. I copied it using the following commands: dick@dick1:~$ mkdir t2 dick@dick1:~$ cp -rf Thunderbird_mail t2

I then ran "thunderbird -P" and created a new profile pointing to /home/dick/t2/me When I opened this profile I got the message "You have launched an a\older version of Thunderbird.", even though I was running the same version of Thunderbird. If I open the profile in Thunderbird_mail/me, it works correctly. If I open the profile in t2/me with the same executable of Thunderbird, I get this message.

How can I copy my profile to a new directory?

dick@dick1:~$ thunderbird --version Thunderbird 115.11.1

Hello, I have been using TB for a long time wiht no mayor problem. I recently had a problem with the hosting services of 2-3 of the email addresses I use in TB and when I now open TB I can click once on the pop up (say on cancel), but when the next pop up message appears (with the same message but for another email address) TB freezes.

I am using Thunderbird to connect to a personal POP & SMTP server. I have recently migrated to a new desktop and moved the old profile folder to the new computer (so I would keep all the emails). Everything was transferred successfully, including the profile settings.

When I open Thunderbird, I am asked for my password and it all goes well if I enter it manually. If I check the "Use Password Manager to remember this password" box, I am met with a "User to server X with username and password failed" - error and a "Sending of password for user did not succeed" - error. I am entering the exact same password in both cases, yet it only fails when I try to save it.

Hi,

I have been configured my Gmail account in Mozilla thunderbird client version 115.12.0 in Windows 11 system. Have been receiving an error message frequently as below "Unable to write email to the mailbox. Make sure the file system allows you write Privileges, and you have enough disk space to copy the mailbox."

System has enough space and memory and please advise.
