It's very odd. Normally moving an email, say from the Inbox to the relevant year's archive, takes "no time at all".

Which is true for all the mailboxes shown on the attached screenshot, EXCEPT for the four at the bottom. Moving even one message from Inbox to Yiddish can take ten seconds or longer (with the dreaded "Not Responding" occasionally). Moving something in the opposite direction is also screwy, only from those four.

I had thought that it was because they're rather large. This first started when there were just Yiddish and MSW, and I split off most of the earlier years into the archives shown. To no avail.

It's only an annoyance, but I'm puzzled about how such a thing could happen.

Also very slow tagging or untagging a message just in those mailboxes.

Aloha. I'm helping a friend with setting up a new Windows 11 PC, and cannot get Thunderbird to connect to Spectrum's servers. I spent an hour on the phone with Spectrum support and they just gave up and said it must be an issue with Thunderbird. Here are the details:

- Brand new Dell 24 All-in-One EC24250 - Windows 11 25H2 plus all additional fixes. - All Dell drivers updated. - Thunderbird V155.0 64-bit

If I click on 'Get Messages' after a while I get: "Connection to server mail.twc.com timed out". I've gone into the config editor and changed mailnews.tcptimeout from 100 to 500 and still get the error.

In the Account Settings | Server Settings | Test server connection I get: An error occurred connecting to mail.twc.com:993.

I've tried this with both setting up a brand new account in Thunderbird, and also via copying the 'Thunderbird' folder from %appdata%\roaming from her old machine.

Email configuration (from Spectrum).

IMAP Settings Server name: mail.twc.com Port: 993 user name: abcd@hawaii.rr.com Connection Security: SSL/TLS Authentication method: Normal password

SMTP settings Server Name: mail.twc.com Port 587 Connection Security: STARTTLS Authentication method: Normal password

Can anyone help me troubleshoot this scenario?

My business has two domains. I can send email to a Gmail account holder using the primary domain with no issues. But amy emails from what I call the "secondary" domain below are treated as spam. This occurs with two different email addresses using the secondary domain.

Both domains are hosted with Bluehost. Exhaustive research has revealed the following:

• Settings in Thunderbird are exactly the same, e.g. ports, security, SSL/TLS, etc. for each domain.
• There is no subject line or content that could possibly be regarded as spam.
• MXToolbox indicates that the secondary domain is not on any blacklist.
• Extended support via Bluehost reveals that SPF, DKIM, and DMARC records are all correct.
• Email sent to a Gmail account using the CPanel (Roundcube) is not flagged as spam. Only emails sent via Thunderbird are flagged.
• Emails sent to a Gmail account from the secondary domain using my mobile phone, but still on the same network/IP address, are not flagged as spam.
• If I first send an email to one of the secondary domain emails FROM Gmail, then reply to it, the reply is not flagged as spam.

After many hours of head scratching (and later, head banging), I am pretty much at my wit's end with this problem. I'm an electronic engineer but this one is definitely out of my wheelhouse. Any help would most certainly be appreciated!

Thanks in advance, Don

This afternoon, without any warning, all my mail in every folder could not be displayed. This is the second time this has happened in the last month and a half. I have two mail accounts - one that goes through Yahoo and the other Gmail. No mail is displayed in either account.

When I run Thunderbird in troubleshooting mode, the mail does display. I then disabled the few addons that I use but that didn't make any difference. When not in troubleshooting mode, no mail is displayed.

Of course, there's "troubleshooting information" but that's way too technical for me to get anything out of it.

I've been a Thunderbird user for over 20 years and I would like to keep using it but this performance is discouraging.

What do I need to do to get past this issue? I'm assuming I'll be able to read an email response by using troubleshooting mode.

Thanks.

Hey guys,

So I am trying to create a rule that will delete emails on the server that are 360 days or older.

I know you can go into settings...

>> leave messages on server >>>>>>For at most ,,,,,,,

But from what I have read that only deletes emails on server from when they were downloaded into thunderbird.

I am new to thunderbird so that wont work for me.

So I went into message filter....thinking this would work

>>>>>age in days > is greater than > 360 days >>>>>>>>>>>Delete From Pop Server

But nothing happens???? Help!

Your input is appreciated

In the last month or 2, when I delete an email it does not show in the trash folder. I can wait from 5 minutes to even the next time I reboot my puter to finally see it it trash. Sometimes it sends it to the all mail or important folder instead of trash. And if I delete from there, it still takes tons of time to end up in the trash folder...if it even gets there. This seems to be getting worse by the day. I have clicked repair folder, no change, I have cleared Thunderbird's cache, no change. It's also now taking way too much time to load an email that contains a picture. This happens with at least 3 of these gmails. I'm at a loss here and extremely frustrated and about to change these gmails from imap to pop. win10 and TB is up to date. But it doesn't compact folders as much as it used to either. Any help appreciated

When I open Thunderbird it is sending my emails directly to the deleted folder. I have tried all-sorts and cannot find an answer. I transferred Thunderbird to my new PC and all was working okay for a few weeks then all of a sudden there were emails missing from my inboxes and I found them in the deleted folder. I am 76 years old and need an easy step by step solution please ..... John

I have settings from Greenby to set up server connections for a new account. They are validated by thunderbird but, after, entering my greenby password, generates the error, below, which greenby claims is a thunderbird problem.

"Component returned failure code: 0x804b000a (NS_ERROR_MALFORMED_URI) [nsIIOService.newURI] Show less

Component returned failure code: 0x804b000a (NS_ERROR_MALFORMED_URI) [nsIIOService.newURI]"

Now my greenby password works on their systems

Now I'm very new to Thunderbird so not familiar with the commands

Any one any ideas ?

After swapping to The Bat some years ago I decided to come back to Thunderbird again. So I installed Thunderbird 155.0.1 (64-bit) on my Windows 11 PC, and gradually re-created and connected the the accounts I had on the back. I also installed the ImportExportTools NG addon, then exported my emails from The Bat to Thunderbird. So far so good. However for some reason I created an account twice. There are both for the same GMX account, but one is POP and the other is iMAP. This mistake probably happened after a long session of setting things up and I just forgot about the first account.

I looked through the Thunderbird help and the answer most given was to the Thunderbird menu, select Account Settings, swap to the account you want to delete, and then press the large red DELETE BUTTON on the top level of its settings (next to the DEFAULT button). I've tried this and it doesn't work. There's no confirmation dialog (which is what I was expecting) and if I close and reboot Thunderbird the account is still there.

How can this be fixed?

In TB 155.01 when I click on Delete the email leaves my Inbox but does not display in the Deleted folder. If I look at Properties in the Deleted folder it shows the correct number of messages in there but the messages themselves do not show in the right hand window. Thus there is no way of seeing what the messages are, just the total quantity in the folder.

I have many years and email accounts on my old WIN10 workstation running all POP installations.

I have a new workstation with WIN11. Is it possible to install TB on my new workstation with my accounts installed as IMAP and keep the same folder configuration? I have many email folders and filters setup on the old workstation installation.

I would appreciate any installation recommendations. I've been using TB for years and would like to keep as much of the current configuration as possible.

now i am getting mail but my dad and my brother both said they are sending mail and it says undeliverable I tried sending to my self and it came through I have Thunderbird through Comcast. i see mail in Comcast that is coming through so i do not know why. the only thing i could think of was they tried yesterday when the update was going through i received a mail at 7.15 this evening so i have no idea why it would bounce back did nothing to change anything

Hello fellow Thunderbirds,

I have been using Thunderbird for years and had thousands of emails in quite a few folders, with a shit-tonne of filters etc. My emails were running pretty well. I only use two addresses, but the folders help manage everything.

I just got a new computer last week. Prior to switching over to the new computer I read through the 'Export your Thunderbird Profile' help page, and the 'Move Thunderbird data to a new computer' pages. I've tried to follow all the info there (with a glitch, explained below).

I am using a Windows system and have gone from Win10 to Win11.

I have the following data:

• Mozilla Maintenance Service (in Program Files (x86) ).
• Mozilla Thunderbird (in Program Files (x86) )
• Thunderbird (In Users/Username/AppData/Local/Thunderbird) (Contains 'profile' and 'updates'

I tried to swap the above data into the same spots on the new computer, but alas, it's not working. I *may*, however, have fucked it up myself...

So... When I got the new computer, I immediately downloaded Firefox, but, alas, I entered my email's details before closing it down. It did download a few off the server, but only a day's worth (before I realised I screwed up).

As soon as I realised I'd mucked up, I uninstalled Thunderbird and deleted the files on the new computer (you know how when you download it doesn't always remove all the stuff, so I tried to do this).

I reinstalled Thunderbird, but closed it prior to loading the email addresses on (as instructed). I then transferred all the above data into the corresponding file areas on the new computer. However, everytime I try to run the program it just goes to the standard open screen (with the popup that prompts you to enter your email addresses and details into it - see image, below, in case I'm not explaining it right).

Anyway, I'd appreciate any help you might be able to give me as I'm desperate to get my emails running again and have access to all the saved emails which were in my system. Kindly. Larysa.

I have 3 email accounts which i unified. when log in I get prompted to enter password for all three accounts which I do, then I get prompted again to enter the password to all Password Manager to save my passwords which I do not want and therefore I uncheck it for all three; I then get prompted again for all three which I enter password, then I get imap login error on my main account which I click cancel a few times before it goes away,

I use Thunderbird portable. How do I fix this issue. it should be that one enters the password for each account once not three to four times. I do not want to use Password Manager to Save my accounts.

Also if ever I have to change password how do I do that? thank for your help.

I have the portable version, download from portable apps website.

Inbound emails are going to Trash instead of Inbox.

No changes have been made. How can I check settings to find a solution? I see nothing related to this issue. Thanks for any help.

Recently I posted about this problem here: https://support.mozilla.org/en-US/questions/1580858 In sum, I was having problems both in downloading messages from the Spectrum server and also with sending messages. I've attached screenshots of the error messages.

Matt and David kindly posted some helpful responses. The problem then seemed to spontaneously solve itself and I breathed a sigh of relief. Then a few days later it re-appeared.

This time it's not quite as bad in that I'll get the error messages but then usually a few minutes later I can download the messages or send an email. But it's still a real problem.

I called Spectrum again and this time the rep was adamant that if I can still use the Spectrum webmail feature (and I can), then it's not a Spectrum issue.

Last time Matt asked about my antivirus. I use Windows Defender (and occasionally do a manual scan with Malwarebytes free version), so if I understood him right, I should be OK as far as antivirus interference.

Matt also suggested I set TB so that I download messages at startup and every 15 minutes. I was set to every 10 minutes so I changed it to 15.

Matt said for me to check the Activity Manager. I've attached a screenshot of what that showed a few minutes ago. But I should note that this was after an error message displayed but my email downloaded anyway.

Finally, Matt said I should check the Error Console (Control + Shift +J). I've attached a screenshot of that. He also said I should use the trash can to clear it, so I did. He then said to press Shift + F5 to attempt to get my messages. But on my laptop, F5 just dims the display so no dice on that. But I have a second laptop and F5 is "neutral" on that one so I tried it there. I didn't get any new error message.

However, one of the screwy things is that sometimes I get all my messages as normal, but only after the "Can't connect to the server" message displays. And that's what happened with my second laptop above.

I hope I've provided better info. this time. And I hope you gents can help me with this mess.

Thanks,

Andrew

When replying to an email or sending a new mail I get the message :- An error occurred while sending mail. Server responded : You need to authenticate when sending mail from (ip address) Please check "message Recipient" and try again. How do I authenticate ? Thanks140.7.1

How can I change an IMAP server on an existing T-bird account after T-bird deleted the saved password and IMAP server for that account? I tried to change the IMAP server address for an existing T-bird account, but T-bird and/or my ISP deleted the saved password and IMAP server entry for that account, so T-bird cannot get incoming E-mails. I would like to add an/the IMAP server back to the account without deleting the account, adding all of its settings again, and waiting 6 hours for T-bird to re-download all of the most recent 10,000 messages in the Inbox and all of the 15,000 messages in other folders again. The SMTP server and its saved password are still in the Saved Passwords table.

Hi, I have a problem with hundreds of Casino type emails filling up my spam folder so I asked AI for help. AI suggested I change my mail handeling from Standard to Strict. Ever since then it will not stay on Standard, it keeps reverting to Strict every time I try to revert it back, therefore all my wanted emails go straight to Spam. I need to check through heaps of Casino emails and take out my wanted emails which is so annoying!! How can I change it back so as it stays changed? I will not ask AI for help ever again, it was working fine until I changed it. Ugh.

I am not sure how to find out what version Thunderbird is, how do I find out please. It should be up to date as I have everything set on automatic up date.

I use an HP Laptop, windows 11.

I read that "Once a message is marked as junk, it will disappear from the main inbox view and be relocated to the specified junk folder." However, that does not happen. Once I mark a message as spam, it just has a red mark next to it and I have to go to Tools and have it "delete mail marked as spam from folder".
