two days ago I lost my email, I did a a get new messages which it did,but all the old disappeared. I do not know anything about this system. It says there are 315 in the in box, but the only thing in the inbox are new messages coming in. Please help

I'm new to Thunderbird and can't solve this niggle. I'm using a Gmail account, IMAP and can't find a way to get rid of this Archives folder in the unified Inbox. I can archive messages to each archive folder under each email address OK. Any ideas anyone. Thanks

Hi. My iMac failed and I now have another. I've downloaded TB to it. In my dropbox account I have a profile backup folder which I'm hoping is what I need. Is there a set of foolproof instructions for restoring from the profile backup?

Hello, Before an update, the backgrounds of mail headers in my inbox changed color according to the color of the tag applied to it. Now there's just a tiny colored tag in the bottom right corner (see picture), which isn't as helpful to quickly identify which mail has which tag. How do I make the background change color according to the tag? Kind Regards

I am on a MacPro Apple M1 version 15.0.1 Thunderbird version: 128.3.1 esr (64-bit).

I click on my Inbox and see the following regardless of inbox or other folders I have set up see the attachment.

I also added the activity monitor. So it seems to be indexing a lot. I need help in getting this fix.

Thanks, Phillip

What are the new folders Inbox-1 and Inbox-2 that were created automatically? They appear to be duplicates of emails already in the main Inbox folder. Can they be deleted?

When I open Thunderbird, new emails download fine from multiple accounts (from 3 different ISPs), but after a time which varies, Thunderbird no longer fetches new emails and even the cloud icon (Get Messages) no longer works forcing me to close and reopen Thunderbird which then will download new emails again.. I checked settings, and all look fine. I have used Thunderbird for many years and this is the first time it has happened. Any ideas? Using Windows 10 Home 19045.5011, Thunderbird 128.3.1esr (64-bit). Any help appreciated

Hi, I've set up my mail using my Gmail credentials but sending with my custom domain as I have with desktop Thunderbird setups. All messages come through with "Send on behalf of" in the from. Can this be changed?

I noticed this when responding to calendar invitations from folks with Google accounts. Google sends me a bounce message rejecting the calendar acceptance notifications because they are not signed with DKIM, since my DMARC settings require all messages to be signed with DKIM. However, the recipient still sees my calendar response in their Google calendar, which is interesting. I checked my sent messages and was surprised to see that the calendar acceptance from Thunderbird is sent without the normal DKIM signature configured on my email server. I run Postfix with port 587 for sending email using the submission protocol, and Dovecot on port 993 (IMAP/S). I may be able to set my Postfix installation to sign the calendar notifications with DKIM using a header check, however, that requires some advanced configuration and I'm not really sure it's possible-- I also noticed that my normal header checks do not seem to trigger when sending these calendar notifications. My question would be why Thunderbird acceptances/declines are not sent through the normal SMTP channels that would trigger a DKIM signature. I didn't see any configuration options for how acceptances and declines are generated, or how to send them.

importing messages stops in the middle of the third pst file. the first 2 pst files were imported successfully. it stops in the middle of the third pst file. there are 4 more pst files to be imported. what can be done to make it continue importing?

Can't change color of the text when composing or replying a message.

The window opens when clicking the box for the color. Can choose the color but after accepting the color it doesn't make any difference.

Frankly I don't understand who authorized this new update when obviously it has so many problems. Why fix something that was working already?!!!!!!!

Good Day,

Hope you're doing well. I want to find out if there is something I'm doing wrong. I receive emails in my Thunderbird inbox, but then before I can check them they all disappear. Also these emails don't come into my Main email account.

Is there a setting that I need to change?

Please let me know.

Thanks Andre

Hi, Thunderbirders -

Regarding the recent HostGator foreign-based DOS attack problem that resulted in having all my messages prior to 10/04/2024 wiped from my host account, I was able to download the entire Thunderbird folder, containing all these previous messages, from my office PC which was not online at the time of the incident, and which I have deliberately kept offline since:

C:\Users\User\Appdata\Roaming\THUNDERBIRD

Now I need the procedure to locate the older messages wherever they are stored in this folder and successfully download them (from 2017, so may have to do this in batches) into the current version running on my laptop, before I again attempt to login to Thunderbird from the office PC. Any step-by-step instructions would be greatly appreciated, and thanks again for all your suggestions so far.

FYI, the app itself is not infected with any virus - the messages were erased as part of the HostGator reinstall process, not a ransomware attack.

I lost my email format and now, when I open Mozilla Thunderbird the only thing that comes up on my screen are all of my SENT emails. How can I get back to the email starting page with which I am familiar and can I keep the emails I've received over the past years? This is very confusing and I don't know how it happened. I've clicked on all of the icons I have available to me and none of them seem to offer any help. I clicked on "restore original columns" but it doesn't take me back to the original email start page. Any ideas?

We just signed up for a Microsoft email account this weekend. Preferring to use TB, everything seemed ok as I was able to receive emails just fine, but upon trying to send emails, I continue to receive an error message saying "Login to server smtp.office365.com with username tom@callablefirst.com failed".

I have gone through many different troubleshooting techniques I read about in the community and here is a checklist of things tried:

1. Checked that IMAP is toggled on in 365 admin 2. Checked that TB is accepting cookies and no exceptions are listed 3. Tried changing SMTP server to recommended instructions from Microsoft and verified all settings are OAuth2 4. Enabled 2F Authentication 5. Used config. edit to clear out all existing OAuth2.scope files

I have downloaded a different email client- eM client and everything works fine sending emails from that end so I am convinced this has nothing to do with my password being entered incorrectly, but some unknown conflict that isn't getting resolved between TB and the 365 account. I prefer using TB but am getting to the point where this is taking a lot of time away from other business activities that need to get done.

I have my marketing guy trying to remotely help figure things out, too, but he is at a loss as well.

Let me know if you have any ideas, thanks, much!

Email provider is Microsoft 365 (via GoDaddy). It is set as a POP account on Thunderbird and all works correctly. When Thunderbird downloads new emails, they correctly show as "Unread." But on our phones (both iPhone and Android) the emails appear as "Read." This occurs even when the email are unread on Thunderbird. If Thunderbird is closed and a new email comes into phone, it correctly appears as "Unread" on our phones. But when I open Thunderbird and that same email gets downloaded (but not selected or read) the email becomes "Read" on our phones. I have gone into both Outlook and Thunderbird and have deselected any options that would automatically mark emails as read. This is annoying because, if Thunderbird is open on my computer, when I look at my phone, I get no notifications of unread email.

I imported a bunch of emails we recieved (EML Files) into Thunderbird, however Thunderbird is not showing me the correct date of the email. In the "Date" column as well as the "Recieved" column it is noting the day I uploaded the emails to Thunderbird. It is imperative to get the dates corrected.

Migrating to Linux after the latest Copilot/Recall issue yesterday.

Setting up Thunderbird for my Microsoft O365 accounts (I have 5 companies I support).

Automated setup for IMAP/SMTP was smooth and no issues. All settings are correct within the application itself. I'm an admin of 3 of companies for O365, and I can confirm that the settings in the app are set correctly.

However, when attempting to send the application will not forward the message. No message inside O365 to indicate why not.
