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

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

When I accessed TB it updated to an ESR (Eclipse) version and when I load it I get a message saying I've used an old version, would I like to create a new profile. ( I didn't) I've copied my backup to the profile but many folders are missing from the current profile.

How do I get all my folders to display? I've reinstalled TB version 147 without the ESR option.

Why did retrieving messages suddenly stop. It was working yesterday and I made no changes to anything. I can send successfully. I am using Shaw/Rogers Pop server.

Why does "test connection to server" fail?

Hello, I am wondering why mail that is 'Junk' and appears in my 'InBox' rightfully marked as such, still shows up, in my "InBox". Why doesn't it immediately get transferred to the 'Junk' Folder, like it use to? Or is there now something that else I have to do, after marking it as 'Junk'? In time past, as soon as I marked an item as 'Junk' it would transfer to the 'Junk' folder immediately. Why does this no longer happen?

I've recently installed Thunderbird and configured it to connect to a few of the email accounts I've setup. For gmail servers, everything seems to work fine. For a locally run hMailServer server, I can connect, download messages, and even send messages - sort of.

When I try to send an email through the hMailServer account, the message sends correctly: it arrives at the other address quite quickly, and I can see in the server's logs where it connected via SMTP, transmitted the message, received a "250 Queued" response, sent QUIT to log off, and got the "221 goodbye". However the Thunderbird UI itself never progresses past the Sending Message dialog: the status stays at Sending message... and the progress bar is full. I can hit cancel and it prompts to delete the draft, etc., but either way, the message has been successfully sent. This doesn't happen with other accounts, so I'm curious what I need to do to get this to go away or send correctly....

I'm using Thunderbird 147.

Purchased new laptop. Used export tool in Thunderbird to external HD. Traded in old laptop. Installed Thunderbird & attempted to import my email profile. Import tool requires zip file, but the only file on my external HD is a .default file. I'm getting new email but none of my old emails. Consulted Best Buy Geek & he determined the import tool didn't work properly because the export was missing required files. We further determined the export backup must not have worked properly.

I use Thunderbird 115.18.0 on a Windows 7 machine. I wish to transfer all my Thunderbird data to a machine running Linux Mint 21.3 which has Thunderbird 128.12.0esr. I have not been successful after many tries. Could this be because the Thunderbird revisions are different? If so, can I get 115.18.0 to install on my Mint machine? If not how should I proceed? I have already tried creating a new .thunderbird directory with ********.default directory from the other machine. I have also tried a new .thunderbird directory with a the ********default-release directory as directed by one site.

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.

I have the same original problem as https://support.mozilla.org/en-US/questions/1508740 , and from the same time period, but across 4 of 5 email addresses, with additional problems. All given answers then & now on this website have completely failed me.

I have 4 emails on the same server, which use IMAP, so there is no way for me to adjust any msg retrieval settings, because they don't exist. Surprisingly, one of these 4 emails actually does work in sending & receiving, but I got different error with it, just now! I also have one gmail affected by this original 2 year old problem, as well.

Closing program, restarting computer, and downloading TB updates all do not work. I uninstalled/reinstalled TB, and all of my profiles & emails were surprisingly intact with no deletes (yes, I backed them up in another folder first), and the problem persists upon reinstall of TB, on the exact same emails as the original problem. Antivirus & firewalls are off. Server said it wasn't them. I'm using Windows 11, McAfee antivirus, and the newest TB dld is Eclipse.

There is no distinct alphanumeric error message for the oldest problem, just the usual "Login to server with username failed. Retry/Enter New Password/Cancel." All passwords are correct. None of my passwords are "saved" in the TB program, and I'm having trouble locating where to tell it to do otherwise.

Screencap and copy/paste attempts to grab second error message failed, but it looked like "RETR failed, one message expunged." So far, it's a one-time error, which I can live with. All emails for that ONE working email are fine.

When I attempt to sign into Google, it takes me to a troubleshooting page https://support.google.com/accounts/answer/32050?hl=en asking me to clear cache & cookies, if I'm using Chrome (which I'm not), instead of just a login to retrieve my gmail.

My emails have been sitting on the servers for 2 YEARS and I am at my wits' end - please help!!!

I just started having a issue where it will be for example noon , and I just get a email , that is not on top but down the list and it says 9am , or similar times where it is 1 or more hours later from the time on the email , but it just showed up , but its down on the list of recent emails , so for example I check emails and a few come in or I get a notice that I have a new email

I have Thunderbird minimized in the taskbar , I never close it , and it will show a email from a few hours ago that just came in , but its below emails that I have already read that were after that time , so basically its like some emails just randomly appear that didn't get delivered when they were supposed to along with the others at that time , this is not a 1 time thing , this has happend several times over the last few days

I can't find any Setting that allows me to choose Newest Emails on Top , or to check the Time to see if it thinks its a different time of day than it is when delivering , or to bring in emails in order of delivery time , newest first and so on , so if a email has a Delivery time of 9:38 am I actually recieve it at 9:38 am , for example I got a email showing the time at 12:48 PM as delivered (10 minutes ago , but I just got the email now at 12:58 am) , then I got one time stamped at 11:15am , and 11:13 am , and at 9:38 am , , the 9:38 am email came AFTER I got the 11:15 email by about 30 minutes , and the one I just now got (it was 12:58pm when I got it , but it shows a time of 12:48 pm so 10 minutes difference from the time it shows delivered to the time I actually got it) , this is while my email is open and I am looking at emails ..... Email Version .. 147.0 ..

Any Ideas ??? .... Thanks .... Jim

Thunderbird downloads from Gmail (a POP server) spam folder. It should only download from the "Inbox", isn't this correct? Gmail is not IMAP, which would dl all folders? Downloaded phishing and spam emails which come from the Gmail spam folder always have an incorrect time stamp.

Hey. New to Thunderbird. I am using the Linux version. I have a couple annoyances I'm sure are configurable, but I can't figure out. FYI, using IMAP and unified folders.

1) I'm watching mail retrieval in the status bar. Seems very one mailbox at a time rather than all at once making mail retrieval much slower than something like Apple Mail. Can that be changed to all at once?

2) This one really irks me :) I'm sitting in the trash folder and right click on it to empty it. It shows it does empty in the status bar, but the messages are still showing in the trash folder. If I click on another folder then back on the trash folder it shows empty. Why does it not refresh to show the current state of the mail folder?

Hello, My SMTP server uses Let's Encrypt certificate. The website with the same domain has no certificate. Thunderbird refuses to connect to my SMTP server. Test connection to the server (STARTTLS) in account settings sais "The secure connection to the server failed" (or similar. I see bg localization). Another server with Let's Encrypt certificate. Test pases. Clicking View certificate shows webserver cert (from DigiCert Inc).

I can't send emails! :)

When adding a link in the composer I get a large image.

I have tried to adjust the page code to give me a more suitable size however it seems the TB overrides the size

My page code reads <meta property="og:title" content="It's complex from 1948 to 2023">

Several days ago we inadvertently deleted batches of emails from our two Thunderbird Gmail accounts on our PC and Apple devices. The lost emails were duly recovered but only after having to change my Google password. However one of our Thunderbird Gmail account will not download any new messages coming in. Ultimately we deleted that account from Thunderbird, intending to reinstall it. We deleted the account by pressing the Red button in account settings. We confirmed that messages are received to Gmail's Web page Inbox Now when I attempt to reinstall the account and press Add Account, I get the UNABLE TO LOG IN AT SERVER MESSAGE shown below. The "Your Full Name" I am putting in is the name on the Google account deleted from Thunderbird, and the password I have tried is my new Google password. I have tried the process of not adding in the password until requested to do so but this did not work either. Any suggestions please?
