Hello, I'm using the most recent version of Thunderbird on a desktop using Windows 11. Just this morning (Aug 11), all incoming email to all my four accounts are coming in with no subject or correspondents showing and when opened the email is not formatted in HTML, just plain text and lots of code. I have tried several fixes with no success: repair folders, turn off all add-ons and anti-virus protection, uninstalled and reinstalled software. Can you help, please? Thanks!

I had a defective hard drive that was replaced. I lost the profiles that I had previously on the old hard drive (Except for the profiles from a year ago). Is it possible to reinstall Thunderbird as if it was a completely new program, link it to Spectrum webmail, and recover all my emails still on Spectrum webmail. and also create a new recreated profile. Thank you.

Att made me change my account password. Now Thunderbird cannot access messages. I have entered the new password in out going and incoming but there seems to be more to this than that because nothing happens. Where do I have to put in new passwords? Thanks so much. Marjorie

Hello

I have been using Thunderbird for many years and enjoy using it. One issue I have not been able to resolve. I have a xx.sbcglobal.net email which is my primary email account and I set it up as such. I also have a secondary email account xx.gmail.com

When I create a new email, Thunderbird almost always selects the secondary gmail account as the sending email. I am not sure what I can do to get around this.

When I create an email such as the attached Craiglist example, both emails pop up, but the gmail, is the one highlighted and therefore the default email address and if I don't catch it, it goes out on gmail.

Thanks for your help !!

Yesterday night Thunderbird updated to 140.1.0esr on my Windows PC. The "new message" button no longer works. The button registers that I press it (short-term slight color change of the button), but a new message is not opened. Ctrl+N does not work either. Everything else seems to work in Thunderbird - for example, I can reply to emails.

I have setup Thunderbird to check for e-mail each 30 minutes. But I never get any notifications of any new mails :-( And mails are only downloaded when I start the app and swipe down. Folders are setup to sync (but "push" is not enabled). Power settings are set to "Optimized" (works for all other apps that check for things).

The Reply command no longer shows when I want to send an email back to the person that sent it. There is a note at the bottom of the email that says: A unique identity matching the From address was not found. The message will be sent using the current From field and setting from identity Vince Hunter < omni232@telus.net> Can you give me instructions in laymans terms to fix this bug and return it back to the way it was?

In previous versions, there was a setting to download messages from the domain email server when you checked for email. This meant that it would reside on my HD, where I would retain a copy no matter what the email server did. When I replaced my PC, I moved to a newer version, but I cannot find a setting to do this, and my emails are being deleted by the server at some point (I wish to retain these.) How do I make this happen? I wouldn't think that this would be a big ask, which is why I don't understand why I no longer am seeing this setting.

why just today is all my incoming emails coming to trasha nd not my in box in Thunderbird worked fine in the morning but i am not getting any mail in my in box it is all going to trash

I have set a "Filter Rule" to forward any email with match to another folder. The issue is those email are also showing up in my inbox. I only need these in the "Moved Folder".

Running Thunderbird with three accounts on my desktop PC - two 'btinternet.com' accounts and one 'gmail.com' account. Inboxes have no more than 20 emails in them, as I delete unwanted ones and transfer others to various sub-folders ( In excess of 40 No.). Today I suddenly found that incoming emails on both bt accounts were not showing the subject or sender and the content is displayed in plain text (txt) format - no problem with the gmail account.

I have compacted and repaired the inbox folders but no difference. If I send a message from either of the bt accounts to the other the problem occurs, but if I send a message from either of the bt accounts to my gmail account, it goes through fine. I can receive bt emails fine on my laptop. I assume this is a thunderbird problem on my PC but not sure where to start - would be really grateful for any guidance.

Since Thunderbird v. 140.1 installed, have been unable to send emails. Get pop-up instruction to check password. Using AOL, which requires OAuth2. But OAuth2 no longer appears in the Authentication Method drop-down menu.

As of today I can receive emails but I am not able to forward or to reply to emails and I can't create a new email. When I click on + New Message nothing happens, the write window doesn't open. I can't get the send new email window. All the above options, simply no longer open a new corresponding window.

I mucked up my decades old Thunderbird e-mail account on my desktop. After a password change in Spectrum webmail, I lost the ability to receive and send e-mails using my old pop-server account. I tried many things at this communities recommendations but no success. So I changed the name of my old e-mail address and then created a new email account with my former e-mail name and also set up the new e-mail account to an IMAP account. Then when prompted for a password, I correctly inputted the Spectrum webmail password and now I receive e-mails to this account on Thunderbird! Hurray!! However, I still cannot send out e-mails from this account as I get the message that the outgoing server "(SMTP) mail.twc.com" timed out. And no - it is not an antivirus issue.

By the way, my phone e-mail account of the same address is able to send out e-mail messages. However, I wish to handle my most sensitive messages to send off of my desktop version of the same e-mail address and that is where I am not able to send an e-mail.

Yikes - Thunderbird.

Why does it take 30 minutes or more before Thunderbird downloads the new messages for the day. Most of the time Thunderbird will not download new message for 30 minutes or more. And some times it will let me know i have new messages and not download them Pleas help. I must have missed some indicator

Thank You Richard Merrell <redacted>

Group contacts have been established and the group is listed in the Address page. An email is prepared and the group name is inserted in the bcc slot. An x appears to the left of the group name. The Send button is grayed out and the email can't be sent. What is the problem?

This just started happening today. The last message to come through normally was today (August 11) at 10:20 AM EST. Every other message today after that time came through as described in the subject of this post.

I am running Windows 10 Pro version 22H2 fully updated through the July 2025 updates. The Thunderbird version is 141.0 (64-bit). No new Thunderbird add-ons have been installed.

The columns for Subject and Correspondents are there, but they are blank for all my messages after 10:20 AM. The message body is like I said—it looks like I selected View|Message Source. I have both of my email accounts for Optimum and Gmail on Thunderbird. Optimum is POP and Gmail is IMAP. The Gmail message that I received a few minutes ago looks normal. The messages accessed on my Optimum webmail account look fine as well so it looks to me to be a Thunderbird issue.

I have tried the following:

1. Repaired the Inbox folder within Thunderbird.

2. Restarted Thunderbird in Safe Mode.

3. Exited Thunderbird, deleting the global-messages-db.sqlite file in my profile folder and restarting Thunderbird.

4. Exited Thunderbird, deleting the Inbox.msf file in my profile folder and restarting Thunderbird.

5. Reviewed all the Thunderbird settings—they looked OK.

6. Rebooted my computer.

7. Uninstalled Thunderbird via Control Panel|Programs and Features, then downloaded and installed the current version of Thunderbird from the official website.

I have uploaded a screenshot of what my Thunderbird screen currently looks like.

Thanks for any help.

I created 3 new email accounts with my ISP. They work as webmail, but I want to bring them into Thunderbird on my desktop. When I try to do NEW ACCOUNT, I get the message there is an authentication error and check my email and password "exchange auth error" it says. But I know the accounts work on the web. I want to bring the messages into my computer.

• Question 1: Is there a maximum number of email accounts you can have in Thunderbird? I presently have 6 but I am going to be closing 3 of them and replacing them with the new accounts after I do the address changes.
• Question 2: Could it be that I am using the same account name in both systems? I had medresearch@dejazzd.com which I will be closing. I am trying to create [edited from public] @gomadison.com (the new address). Is that causing a problem?
• Question 3: There used to a place in Thunderbird NEW ACCOUNT to do a manual or custom installation. If I can get to that link, my ISP will help me.
• Question4: Is there a phone number I can call in Mozilla or pay for support to be able to call? Thank you.

Right after the latest Thunderbird update, my emails are coming into the inbox, then being redirected to a subfolder where they don't meet any of the parameters set in the message filters. There is no reason for those emails to go into that subfolder. Funny enough, the emails that should go into the subfolder are staying in the regular inbox. I don't know what to do to fix this issue. I have checked my message filters, and all the settings are correct. This just started happening after the latest Tbird update.

One other thing, the subfolder now has this yellow star icon beside it. I can deselect it manually, but when another email comes in both the email and the folder display this yellow diamond/star icon again.

Is anyone else having the same problem, and what is the solution as nothing I have tried worked.
