Good day,

On one of several computers we use to access email when we try to 'Get Messages' Thunderbird doesn't even attempt to connect to the mail server on two of the accounts set up. All four other computers access the servers just fine. In trying to resolve the issue on the recalcitrant computer I created a new email account with the host and added it to Thunderbird using the 'Add Account' wizard, and changed IMAP to POP3. Once the account was created it logged in and received the 'settings' email from the host, and I was able to send an email to another account. I could see the activity reports for the new account in the status bar. However no reports on the status bar for the original two accounts. I've triple checked port settings etc and up until a few days ago Thunderbird worked just fine on this machine. No changes have been made to the original settings. Prior to adding the new account, when asking to get messages the only report on the status bar was 'Done' without any information reported about contacting, downloading etc. The Done message showed up immediately upon clicking the Get Messages button.

Adding the new account and it working properly tells me my settings are correct and the install of Thunderbird is working. Thank you in advance for your suggestions.

I've come over from Postbox as that app is no longer being supported. In Postbox there was one file (panacea.dat) that controlled how many old locations you would see in the Move To menu. Once the number of items got to be a bit too muchj, I would delete that file and it would clear the Move To menu item. Is there such a file in Thunderbird that controls the Move To menu, or can it somehow be controlled by a setting in Thunderbird? Thank you.

My thunderbird email is broken and I cannot interpret the error message. I found a similar problem at https://support.mozilla.org/en-US/questions/1281109, but I have not been able to follow the solution.

The error message is:

Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) promail.ptd.net failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again.

When I access my email at ptd.net, using firefox, I can make a full connect. But I cannot connect to email using Thunderbird, which is my preferred email tool.

My hope is to have a dialog in this thread with someone who can walk me through the steps to get thunderbird working. Can someone help?

good day....ii hope someone can help. the other day i was accessing my yahoo account spam folder and by accident, i deleted the spam folder instead of emptying it. the spam folder is now sitting in the trash and i'm unable to remove it from there. when i log into my actual yahoo account, the spam folder is where it's supposed to be and not in the trash. i tried removing the yahoo account from thunderbird and reinstalling it in hopes that it would rectify the problem, but it hasn't. does anyone have a solution?? i would greatly appreciate any help you can offer. thank you for your time...mike s

I can't sign in to my email ([edited] @yahoo.com) on my desktop running Windows 11 Pro. I have changed password which has been confirmed with still no joy. I get the message:-If you still can't sign in try a different device. My wife can sign in on her Android phone but I can't

How can I filter the list of emails in a folder? There's this 'Ctrl-K' search box but does nothing like I want. I just want to filter the displayed list of emails by correspondent. The Ctrl-K system is a baffling mystery, AFAICT you always get a search for 'mentioning' of the search string, whereas a filter for correspondent would be useful too.

Hi, I am trying to export a calendar from a Windows 10 PC into a Lubuntu PC. The exported Home.ics file is about 217KB. At stage 4 in the import process (which shows the file name correctly) a message in red says "No importable items found in the file" . In the main area it says "Loading items" but nothing happens. Am I missing something here? Thanks

Hi there! I and my colleague encounter some bugs with Thunderbird and we would like to seek your advice in regards of the issue.

1. <user a@citizen-systems.com.hk> was supposed to get a cc copy of the email sent by <user b@citizen-systems.com.hk> at Mon, 12 Jan 2026 09:35:19 +0800 but it never reached. The receivers, namely <user c@systems.citizen.co.jp> and <user d@citizen-systems.com.hk>, however, were able to get the mail. <user d@citizen-systems.com.hk> and <user a@citizen-systems.com.hk> are working at the same office and under the same network. Network provider checked the protocol, router, traffic and firewall are working as normal.

2. <user e@citizen-systems.com.hk> found a number of emails that she kept at "Inbox" disappeared on 12 Jan 2026 morning +0800.

She is unable to find it anywhere at her whole mailbox but has to ask the senders to resend them to her.

It would be very much appreciated if you can check and advise how to prevent the issue from happening again.

On my PC Thunderbirds sending/receiving mail says the mail server refused my connection. My laptop works fine. I have duplicated my laptops in/out specifications onto the PC but still nothing works. Spectrum says everything on their end is fine but can't vouch for roadrunner who is the rr in my mail address of ca.rr.com. All this started about 4 days ago. Any ideas on what to try next? Thanks.

Hello:

I use Thunderbird for work. I have several email accounts configured in it, including Gmail, my company's email, and Outlook. I recently added a new Outlook account, and I haven't been able to send a single message. The error I'm receiving is the one described in the title. It's worth noting that I have another Outlook account working perfectly. I've tried every solution I've found online, and none of them have worked, including enabling SMTP in the account settings, making sure OAUTH is enabled, using smtp.outlook.com or smtp.office365.com instead of smtp.mail.outlook.com, enabling two-factor authentication, changing my password multiple times, etc.

My old email server was Mediacom (mchsi.com). I had that email account plus a gmail account on Thunderbird. Sometimes people said their emails to my gmail account would bounce. I changed email servers and no longer have the mchsi.com email or Mediacom server and have 2 gmail accounts on Thunderbird. The new one works fine. When I send an email to the old gmail account it bounces back saying "address not found. Your message wasn't delivered to ------@mchsi.com because the address could not be found or is unable to receive mail. 550 5.1.1 I had the tech that sold me the PC look at the settings on Thunderbird for the gmail account and he said they were okay. Where else can he check? Somehow the pc thinks that just that one gmail account is run through or attached to mchsi.com Kathy foggiak@gmail.com

I can't log in after changing my email password. My email address is anita.bodin@telia.com. I can log in with my new password using Telia Webmail. I have been in contact with Telia and they refer you. Best regards Anita Bodin

Hi, I’m using Thunderbird with a Yahoo Mail account and I’m seeing two Draft folders in the left pane:

Drafts Draft

Their IMAP locations are different: imap://…/Drafts imap://…/Draft

Thunderbird only saves drafts into the Drafts folder (plural). The Draft folder stays empty, but it always shows up.

What I tried so far: • Account settings → Subscribe Unchecked “Draft” there, but it doesn’t save. After reopening Subscribe, it’s checked again and the folder is still visible. • Restarted Thunderbird multiple times. • Server Settings → disabled “Show only subscribed folders”. • Checked folder Properties, but there are no options to hide it or control visibility, so it looks hard locked by Yahoo.

Conclusion so far: Yahoo seems to force both system folders via IMAP and ignores unsubscribe, so Thunderbird can’t hide or remove “Draft”.

Is there any supported way in Thunderbird to permanently hide or ignore the extra Draft folder for Yahoo accounts, or is this a known Yahoo IMAP limitation?

Thanks
