I'm setting up TB for the first time. Have imported my contact list into TB from Google, but in my TB address list their email addresses are shown under Nicknames instead of Email addresses. Is there a way of changing this en bloc, please? Don't fancy having to click and drag them all across.

I seem to have acquired a shadow email account labeled IMAP. I'm using Thunderbird fetching from Gmail. The IMAP account seems to delay populating the regular account. Any idea what I should do?

Both my wife & I use Thunderbird on separate computers. Mine is working fine. In my wife's thunderbird account, all email in every folder are no longer displayed. I already tried to rebuild the register for each inbox with no success. What do I need to do in order to restore the display of her mail? She uses this for business, so this is critical to resolve.

My Thunderbird application is either deleting or hiding emails. So far, it appears to be emails I send and copy my self on. I included a BCC to my second email and still it disappeared.

I initially receive the emails, but once I exit Thunderbird, then later launch Thunderbird again, initially the email is present, then it disappears.

I have no idea what to do to correct this issue, if it is something I can correct.

I am running Thunderbird version 115.18.0 (64-bit), on Linux Mint Cinnamon 21.3

I hope there is a fix for this. I do not like seeing my emails disappearing before my eyes. This is a weird issue.

Thank you,

Clarence Hayes

Hi,

I put some messages into folders yesterday and then created another folder and dragged the first folder into it to become a subfolder.

When I did this, I saw the new folder but it couldn’t be expanded to show the subfolders.

All other mail clients showed the correct hierarchy except Thunderbird.

Why is this happening?

Secondly, I post comments on the thunderbird blog regularly but they never show up. Where are they disappearing to? Are you receiving them?

Hello, My thunderbird is displaying the following message when I forward an email. "An error occurred while sending the mail. the server responded the "name file.eml" attachment has been dissallowed extension". This error also occurs if the message you forward does not have attachments. my account is configured with pop. How can i solve the problem .

thanks

On Thunderbird on macOS, I am trying to use a Security Device to client certificates made available by the OS for TLS authentication to IMAP servers and S/MIME signing and encryption. Under Security Devices, there is no Security Device that provides this functionality so in Security Devices I click Load and Browse... and select /Applications/Thunderbird.app/Contents/MacOS/libosclientcerts.dylib to add the appropriate security device. However, when I click okay, I get "Alert" "Unable to add module" . What am I doing wrong?

I also use libosclientcerts.dylib in Firefox just fine. Why is it not working in Thunderbird?

Dear technician,

I have configured my email account to Thunderbird mailbox, but the email sending speed is too slow and cannot be sent successfully.

When using Thunderbird mailbox mail merge plug-in, it always shows: Your email has been sent, but due to network or file access errors, the copy could not be placed in the outgoing backup folder (sent). How to set up the account to solve this problem, you can put the email into the outbox or draft box of the email account.

How to activate Thunderbird mailbox account enterprise version and enterprise version fee and daily email limit?

Hi All,

2 Days ago, I stopped receiving all emails into my 5 inboxes with Thunderbird on Windows 11 desktop.

Tried some troubleshhoting including updating to the latest version of Thunderbird version 128.7.1esr (64-bit) on desktop for Windows 11, and turning VPN off and on.

Would appreciate any troubleshooting ideas to get emails flowing again.

Thank you

Hi All,

It's almost like I don't have connectivity to the Internet with Thunderbird when I have it with all other applications. Today, Thunderbird stopped working, sending and receiving email. For me that may be a good thing, given the number of junk mails I get but there are some important ones in there as well. I can see my mail if I directly to Comcast, but not Tbird. I also can't send email either. Has anyone woken up to this nightmare?

Regards,

Ernie

Just setup a second Thunderbird profile for Exchange. Using Owl for Exchange plugin.

I right click onto a subfolder, and pick Properties, then go into Synchronization. I click onto a checkbox for "Select this folder for offline use" and I hit OK to close the window. Nothing happens. I go back, and the checkbox is not checked. I tried hitting the Download Now buttons, nothing happened.

Any clue why my check box selection is not accepted?

When I used Outlook, I set it up to use OST, so I have a copy of my email that is on the remote Exchange server. Now I am trying to do the same with Thunderbird.

Thank you

Today I opened Thunderbird and found that half of my address book entries are missing. Also it takes several seconds for the address book to load. What could have happened? If I need to reinstall Thunderbird do I need to erase the existing program before reinstallation?

Hello

Overnight Thunderbird has developed a major problem. The count for the number of mails in a folder is correct, as best I can tell, but when I open the folder it is either empty or has fewer mails than the count. Based on several tests, repairing sometimes adds more mails, sometimes not, but never the entire folder.

I repaired the inbox and it is now showing several mails that I deleted in the last few days (by emptying the delete folder having previously deleted them). Curiously, they’re all the same type, routine mailings about road works.

I may have backup in that I copy the entire Thunderbird folder to an external drive every morning, including today, and to Google Drive every Wednesday.

Please can you help.

Thank you

I’ve got a minor but annoying Quick Filter button issue which just cropped up today out of nowhere, and haven’t been able to find an exact match for all these symptoms in any other problem reports.

Toggling my Quick Filter button works as expected, picking up the individual active filter buttons. However, in some instances of launching TB its on/off status indicator always displays as active regardless of individual filter button status. Weirder still, in other cases it always displays as inactive. It’s an intermittent problem, which always persists in one way or the other.

Further details:

- Problem is also present in safe mode, with the single plugin I use (CardBook) disabled.

- General display settings are “Theme Simple” and “Variant Normal” (not “Dark”).

- There are no automatic filters configured in “Tools > Message Filters”.

- Individual filter buttons are all working properly, including correct status indicators.

- Running current TB version (128.7.0esr 64-bit) on Windows 10 with all OS patches up to date.

An example:

Image 1: “Show only unread messages” button is active, and the Quick Filter button also displays as such (both indicators are correct).

Image 2: All individual filter buttons are inactive, yet the Quick Filter button still indicates a filter is active.

I’m stumped, thanks in advance for any help!

The enter password dialogue box to open thunderbird to receive and send messages is now very slow to popup. This occurred after the request for donation hijacked the program functionality. Email colour scheme also changed. Any thoughts to rectify please ?

I run Thunderbird 115.18.0 (64-bit) with calendar and tasks connected to a NextBase Caldav account on the web. The Caldav then syncs with my Android phone using DAVx.

When I try to add a new task but without adding start and end dates it will initially appear to save and show in the tasks list. However this is lost following a Thunderbird restart. NB the task view is set to "All"

If I either edit the task to add start and end dates the task disappears from the task list. Similarly if I create a task with start and end dates the task does not save.

This issue only seems to have started recently as I have been using this process for a while without issues.

Is there a way to fix this?

Using TB 115.15. When I delete a number of messages, then empty the trash, I cannot delete another message until I restart Thunderbird. Is there a limit as to the number of emails I can trash prior to emptying the trash?

bold textover the past week several times my Thunderbird does not show any emails from 7 or 9 pm until the following am. I know, from accessing through aol that there were many messages that are completely missing. In addition, several important emails from different dates in Feb are also missing although because they were sent to multiple others, i received notice of them. Why is this happening. I cannot loose clients because I did not receive messages!!

Dear Thunderbird Community,

First, thanks for any help and guidance anyone might be willing to provide.

I have an issue where the "Date" and "Received" columns (in my Inbox) always show the same exact date/time even when the message source shows a different date/time for the "Date:" header verses the "Received:" header.

I know this has been asked before, but the suggestion of adding "Received" (without the quotes) to mailnews.customDBHeaders, restarting, and then repairing a folder did not work for me. I am on build 128.7.1esr (64-bit).

For example, I emailed a message to myself, selected to send later, waited a few minutes, then released it from the Outbox. When the email came in, it showed "2/23/2025, 11:27 AM" for both the "Date" and the "Received" columns. If I view the email source (some data removed for clarity) I see:

X-Mozilla-Status: 0001 X-Mozilla-Status2: 00000000 Received: from 127.0.0.1 by atlas-production.v2-mail-prod1-gq1.omega.yahoo.com pod-id atlas--production-gq1-dcf999469-vgzhb.gq1.yahoo.com with HTTP; Sun, 23 Feb 2025 16:32:18 +0000 Return-Path: <XXXXXXXXXXXXXXXX> . . .

From above, the "Date:" header has "Sun, 23 Feb 2025 11:27:45 -0500" which is correctly displayed in the Date column as "2/23/2025, 11:27 AM" however, the latest "Received:" header has "Sun, 23 Feb 2025 16:32:18 +0000" (which is 11:32 AM Eastern) but the Received column shows the time as 11:27 AM instead of 11:32 AM.

Might anyone have a thought as to why I can't get Thunderbird to show the correct Received date/time?

Thanks.
