Thunderbird コミュニティフォーラム

This post is more for posterity than asking for a solution because all similar topics ended up being Avast antivirus interfering or something less nefarious.

In my case eM client started having this problem first, then I switched to TB, but the same issue here. Of all places, the best clue was found on [[Linux mint|https://forums.linuxmint.com/viewtopic.php?t=213352]] forums. It was a permission problem. Right click on C:\Program Files\Mozilla Thunderbird -> properties -> security. I did two things and not sure which one did it, but they pretty much achieve the same. ...

The Users group in the list only had read permissions so I gave it full access to the folder and checked the option to set the same permission changes to all subfolders. I also added my own personal user to that list and gave that full permissions. Oh yeah, also changed owner to myself from whatever default windows group was there before.

Now, do I know the full repercussions of doing this? No. Pretty sure this just created a security hole inside my C drive, but... I don't really care at this point. If I had to fix this again, a solution might be to instruct TB to store the the email files somewhere else rather than where it is installed itself (somewhere less locked down than Program Files).

I keep getting a message that says the login at imap.mail.att.net fails. So I re-enter my password, and it still doesn't work. The outgoing works fine. My server is Yahoo/AT&T.

I have an email address and I want to migrate those emails to a gmail address. The problem is that I have around 2300 emails. I'm copying about 200 emails to the gmail address. The problem is that is taking too long and it's not copying all of them.

What if I copy all of emails wait to sycronize it and then copy it again? It will work? Or is there another way to do that?

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

Twice in the last fortnight Thunderbird has lost all email passwords - the Tools/Settings/Privacy and security/Saved passwords just leads to a blank box where the passwords usually are. Thunderbird will no longer collect email and keeps asking for passwords for email accounts. This happens even when the option to 'save password' has been selected. I think this is probably happening at the point when the PC is rebooted. Thunderbird version 153.1.1esr (64 bit) and Windows 10. Using System Restore has not resulted in recovery of passwords. Several different email accounts/email providers are involved - outlook.com, tiscali.co.uk and zohomail.eu. Broadband provider is Zen.

I notice that the Appdata/Roaming/Thunderbird/Profiles/w2anb37y.default folder contains a number of files named with such names as 'logins.json-8.CORRUPT' - with 'Date Modified' being mostly either 17th August or today 31st August - so it might look as though password data is becoming corrupted.

Can you assist?

I am using Thunderbird 154.0 on Windows 10, 64 bit. When I press "Send" on an email I have composed, I immediately get an error message, and sometimes on the second try, but it goes through on the 3rd try. I did get a new modem from my provider recently, but it worked fine for a couple of weeks, then this started. I contacted them thinking it might be a port issue, but after trying with their support and no solution, I am stuck. They indicated their connections are working, and I agree since it will go after 3 tries, but is very annoying.

When my machine reboots (far more often than I'd prefer, tbh), Thunderbird starts automatically, and works fine. Messages sent and received. Eventually, some accounts just stop receiving.. afaik, I'm sending fine (although, I might never know), but I realize after a while that some accounts have not received for a few days. I run "Get Messages" on specific accounts - like waiting for a 2FA code, and usually they come in. But then I restart T-bird, and a flood of mails from (sometimes) 5 days ago arrive; missed invoice requests, Tax Dept, reminders, Customer replies, and (even more important, Dominos deal vouchers !)... very inconvenient.

'Anyone else experiencing this ?'

Network is fine, PC is online (trust me, I'd notice) Some emails arrive, usually in other accounts.

Tbird version: 140.14.1esr (64-bit) - but I think it's just doing an update now (esr channel) Accounts with issues are POP, my own domain, so I control everything.

Can't tell how often or after how long this occurs, as usually I am swamped with work once they come back online.. so I don't make records.

I will though.

Good morning, Thunderbird was preventing me from accessing one of my accounts, and the support team for that account told me that changing the password would resolve the issue, as is the case for all users of that provider. Instead of changing the password, I deleted the POP server credentials line for that account. Since I received the error I mentioned in the header of my question the next time I tried to download messages, I simply changed the password for the SMTP server credentials, which now works. I asked Thunderbird to ask me for the password again to access the POP server, but even though the credentials line reappeared with the correct information, Thunderbird continues to give me the same error, while I can connect to the POP mailbox with other programs or via webmail. How can I resolve this issue? Thanks in advance for your help.

For no apparent reason the calendar display has been filled with multiple columns of light and dark blue, side by side and extending top to bottom. This pattern starts in The August 31st column and continues up to and including September 7th. After that the display goes back to normal. Does anyone know why this has happened and how to fix it? Thank you.

After your upgrade I was unable to send messages. The incoming I was able to fix but the outgoing I could not fix. I have included the email message sent to me and I have included a picture of the outgoing STMP,

I wish to back-up my Thunderbird profile, but apparently, I am to find an "export tool" under the "tools" menu. Unfortunately the option to 'export' does not appear in the list [but "import" does...!]

I use Windows 10 with the task bar on the Left side with added tool bars for lots of quick links which makes the task bar wide. When I copy & paste in Calendar the paste window is under my task bar. Why do you have the paste window always placed at the 0,0 window position?? Can I change the position? I will be using Win 10 for along time. My other notebook is on Win 11 where I use StartAllBack enabling me to have the same left task bar.

In Thunderbird, how can I stop text in the previous emails in a string turning blue?

I have looked everywhere in Settings where colour is mentioned and everything is set to black text on a white background. Nothing is set to blue.

I do not want to see blue text anywhere.

Please advise.

thunderbird has stopped downloading email from charter. it will work if i have a vpn open. i think the problem is with charter. i can get email if i go right to their website, but not with thunderbird or outlook. i just chatted with charter last night and they denied a problem. it has been messed up for a couple of weeks . i have been contacted by several friends that they are having the same problem. not sure why it isn't working. i have checked all the server settings. the weird part is if i open my vpn i can get my email, if that is a clue to what is going wrong. i posted a picture of their website that says they ARE having issues with legacy emails accessing email from charter/ spectrum.

“My Spectrum email address is [redacted]@charter.net. Spectrum webmail can send and Thunderbird can't receive or send. The outgoing server is mobile.charter.net and the connection times out. I tested the connection from my computer and ports 587 and 465 both respond successfully. Thunderbird is set to No Proxy. when i tried to send today, it gave me this message, "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) mobile.charter.net timed out. Try again." i contacted spectrum about this and now when i try to send, it says nothing and the message never arrives.

This started happening a day or so ago... When I type part of an email address, Tbird shows all email addresses starting with it. Now the length is as long as the screen.. Any ideas? Thanks.
