Thunderbird Community Forum

Thunderbird just updated itself to a state where I need to do the setup process manually, which always takes a few hours (with networksolutions as the host). How can I continue to work with the previous version until the bug is fixed or I have time to go through the entire complicated process? Thanks in advance, Knut

I was using MS outlook and recently I could not connect. Apparently ATT made a change so that instead of a password you need a Secure email Key. Since I needed to make a change I thought I'd try Thunderbird mail, but I still need the KEY. After a number of efforts with the ATT AI and human support people I could not find where the Key is entered on ATT. Now I know this forum is about Thunderbird and not ATT, but there must be Thunderbird users that have ATT and have made a seccussful connection. There are a few ATT help pages that outline how to do this, but each time I look at my ATT profile I can not find where to enter the Secure Mail Key. Is there anyone that can help me with this? THanks Mike

Hi. I have recently compressed thunderbird which has wiped two servers. I have three pop accounts on thunderbird. I have a functioning email service on the machine that I compressed but another machine and my smartphone have no emails. I have checked on the servers to confirm they have not archived or trashed my emails but everything is gone. How can I reload the servers from my only good copy?

I have lost the indicator in the folder pane showing which folder I'm in. It used to have a small color tab in the folder pane on the left hand side. Indicating that the folder was selected. Any ideas to get it back? Thunderbird 140.3.1esr (64-bit)

Suddenly, my "main" comcast account is no longer accessible via Thunderbird. I have three accounts set up: two comcast and one gmail. The gmail and one comcast account appear to be all right. When I try to access the comcast one I call main, I receive the window shown in the uploaded image. It seems as if TB has somehow forgotten the way it accesses "main" accounts. I have verified that the "main" account is fine on the comcast server by logging into it. The question is if I remove the TB "main" account and recreate it, will I lose any messages? Is this likely to correct the issue?

Hello,

I have Thunderbird version 140.3.1esr (64-bit) , everything looks good with multiple accounts , except there is a big issue on reading emails: 1- when I double click on any email I get the email as edit mode and not like when I press F8. when I press F8 the email looks normal, but when I double click not.

2-Some emails received as HTML format reads the body as HTML attachment. 3-Some emails show part of the email and not all text with HTML format.

Hope the developer know about this issue and someone can help me to solve this issue if work around.

Thank you

I have Thunderbird v140.3.1esr (64-bit) on Windows 10. I made a new calendar based on a google calendar. I have 2 google calendars so I am trying to import the second one from an .ics file exported from Google calendar, but each time I try it gives me an error message.

An error occurred when writing to the calendar MyMotog! Please see below for more information. Modification_failed If you're seeing this message after snoozing or dismissing a reminder and this is for a calendar you do not want to add or edit events for, you can mark this calendar as read-only to avoid such experience in future. To do so, get to the calendar properties by right-clicking on this calendar in the list in the calendar or task view.

It has installed itself as a second calendar in Thunderbird, but I've no idea why I can't import the one into the other?

I accidentally discovered that dozens of email messages for a specific period of time (about a week) are still on my ISP's email server. Thunderbird is configured to download all messages to my computer and then delete them from the ISP email server.

Prior to, and since, that period of time (for many years) this has typically worked. Now, however, nothing I do to Thunderbird will get those messages downloaded - I can only access them using my ISP's webmail portal.

Based on web research, I've tried deleting the popstate.dat file and the global-messages-db.sqlite file to try to get Thunderbird to rebuild its indexes and/or POP3 databases to no avail. I've also tried to flag the messages as "unread" using the ISP's webmail portal, again, without success.

Any suggestions?

I have number of email filters in use. The main set of filters are all configures to "Filters for Local Folders". As I have a Gmail account I have a set of filters set to "Filters for <gmail address>". The Gmail filters always move the emails to my Inbox folder. These are then picked up and moved by additional filters in the "Filters for Local Folders".

Previously this worked well. However, under the latest release 143.0.1 under Windows 10, there are emails left in the Inbox folder which should have been filtered within 10 minutes. Often they are there for many hours before being processed.

When I have unfiltered emails in the Inbox folder, to make sure the filters are correctly configured, I run the "Run Filters on Folder" option on the Inbox folder and it works perfectly.

I am trying to sign an email with my dsc token. Token contains Digital Signature, Non-Repudiation and E-mail Protection, Document Signing, 1.2.840.113583.1.1.5, Smartcard Login, Client Authentication key usages. Encryption is not required. Only want to sign. Able to see the the certificate in both account setting and thunderbird settings. But still when I select sign and try to send a mail, not prompting for PIN and failing with " Sending of the message failed. You specified that this message should be digitally signed, but the application either failed to find the signing certificate specified in your Mail & Newsgroup Account Settings, or the certificate has expired." error message

How do I add a person's non-default email address to a mailing list?

I have a mailing list for our golf league, and in my address book many of those in the list have both a work and home email address, with one marked as the default. Some of our members would like messages sent to the list to go to both addresses. But I haven't found a way to add a person's non-default address to the list.

Do I need to create two address book entries for each of these people, one for each email address, and separately add them both to the list? That seems awfully klunky/inefficient to me.

Good morning

Thunderbird is not sending or receiving emails, i already deleted the gmail account and reinstalled it but it didn't work upon installation i get the attached message.

this was running on a windows 7 pc with no issues for about 2 years.

thanks in advance

I recently noticed that some of my local folders are missing. Not all of them, but some of them. Following some advice we found in the forums, we closed Thunderbird and then deleted the .MSF files from the Local Folder. When we restarted TB, we had more of the local folders, but were still missing 18 of them in the alphabetical order they are listed in. I created a new profile and copied the local folders over to the new profile. When I started TB using the new profile, there were fewer local folder listed than before. Went back to the previous profile and had the local folders that were still missing 18 folders. I see that there maybe a bug for this being researched as I saw 4 other posts in the forums regarding this recent problem and wanted to get my problem noted also. Thank you.

I downloaded Thunderbird to copy all my yahoo emails plus their attachments, and then taking all of those and saving them to an external hard drive. It took days but I think the first step was accomplished. How do I export all those emails (files, groups) with their attachments to a file on the external hard drive? My goal is to then delete all the emails from Yahoo, but still have the emails. I noticed that if I delete an email on Yahoo that was saved on Thunderbird, it is deleted from Thunderbird. I need Thunderbird to save all that it has. I want to clean the slate on yahoo, but need the emails for personal and business reasons. Respond to me as if I'm two years old -- not so computer literate. TIA

When sending an email a message states: COPYING MESSAGE TO SENT ITEMS FOLDER It never goes away. I deleted and reinstalled the program without changing the outcome. This is a Windows 11 machine.

Recently when I delete an email from the inbox it is also deleting the following message. I would appreciate it if you could tell me what is causing this and how to correct it.
