Thunderbird Send message Error Sending of the message failed An error occurred while sending mail. The mail server responded: Must issue a STARTTLS command first. For more info, go to https://support.google.com/a/answer/3221692 and review RFC 3207 specifications. ffacd0b85a97d-47aa0f2186bsm33992962f8f.36 -gsmtp. Please verify that your email address is correct in your account settings and try again.

Note: I could not find the suggested specifications as indicated in the error message!

I did not change anything, the sending error occurred suddenly , all my settings IMAP Mail Server Port 993 SSL/TLS OAuth2 and SMTP Port 465 are still set to default. I changed also the SMTP to an new shown default 587 but non of this settings resolved the problem

To my new computer Thunderbird has just fetched the INBOX-mails from the IMAP-server, not my many subfolders, not the SENT-folder, not the SPAM-folder. This has previously worked when I changed to a new computer. How do I get Thunderbird to transfer these mails.

Email problem. Old Lenovo Desktop, Window 8.0 (I know, I know, but it's my wife's and all she uses it for is email and utube recipes, and she's used to it). I use it for some banking, mainly because the printer is on it. Tbird 115.18.0 (32 bit) -says it's up to date AVG antivirus free

Email through yahoo. It worked fine until, going by the last date it linked email, 10/30/25 at 06:45AM MST When I tried to download new messages Sunday 11/2, it failed.

It pops up a new window "Enter credentials for bababarb@yahoo.com on imap.mail.yahoo.com" In the address window is "https://login.yahoo.com/?src=thunderbird&client_id=(about a zillion characters) Then, in the message window is "Edge: Too many requests"

So, I did the troubleshooting as in Help article. I logged in on the webmail, signed in with the password, and was able to see the messages, many from after the 30th (she gets a ton of sorta spam).

Looking under Account setting> server settings, I find that the security is set to SSL/TLS and Authentication is set to OAuth2. Incidentally, these were set automatically when I set this to a yahoo.com address.

So, I try setting the Authentication to Password and request mail. I get a popup asking for the password. I enter it (the same password I used on webmail) and it replies "Login to server imap.mail.yahoo.com with username bababarb@yahoo.com failed."

Following suggestions on the help article, I got to Settings, and check "saved passwords". Then, again following the suggestions, I remove the yahoo password entry. According to the article, the next login attempt should ask for a password. It does not. I just get the "too many requests" popup. What the hell, I go back and remove the SMTP password, too. Same result.

Anybody else having this issue? Any suggestions?

"connection to server pop.mail.yahoo.com timed out" I have been getting this message in the activity manager for about a week now. When I click get messages, it says down loading message 1 of 1, but nothing happens.

Hello, I use Thunderbird to manage several email accounts, one on them is not active anymore but I still want to be able to access the emails stored in my thunderbird directory tree, so I keep it active. And the fact is that every day this account tries to access a remote server that does not exists anymore to retrieve email that can not be retrieve, and every day I am asked for a password that cannot work. But the fact is that I did deactivate all options to read remote emails for this account, so that behavior is odd and I am not able to find a way around it. Any idea what to do not to be bother anymore ?

Thanks in advance for your help :-)

This is a new thing. The 2 devices (laptop and Kindle) have always synced my Outlook emails. New today. Can be fixed I'm sure but don't know where to start. Thanks!

I was forced to change email from Comcast to Yahoo Mail and hate it. Downloaded Thunderbird and connected my gmail address, but it won't accept my Comcast address, which I use on Yahoo Mail.

I have a desktop that is windows 10. I use Mozilla for four email accounts, 3 of my accounts work fine. My problem is with TWC. Emails sent/forward and cant save drafts often fail. When I sign into spectrum webmail, my Mozilla TWC account works again for a while. This started about 2 weeks ago. I'm using version firefox version 151.0.2. I've eliminated Spectrum as being the issue and all my settings are correct. Thoughts?

I am trying to add a new identity, I already have 3, so perhaps there is a limit? I have created the identity under manage identities with no problems. However, the new identity does not appear in Thunderbird, where the others are. The address is not recognized, and does not receive emails. I feel like I have missed a fundamental step but have followed the help instructions & cannot see what I am doing wrong. Ive checked and the program is up to date. I hope someone can offer advice thanks Anne

I am using Thunderbird 152.0 in Win 11.

I am trying to move about 100 emails from one folder to another in the same account. 1. I have selected all those emails to move and dragged them to the new location. One email moves. 2. I have selected all those emails to move, right clicked and selected Move to/email account/different folder. One email moves.

These methods used to work and all emails selected would move. For some reason they don't move except one.

What am I doing wrong now?

I was able to successfully set up my gmail account, but there's a problem with my iCloud (me.com/mac.com) account. This account is accessible on my iPhone and also on my laptop. I don't really know where to begin troubleshooting this. By clicking on Manual configuration I can see Thunderbird's best guess, listed below:

Protocol: IMAP Hostname: imap.mail.me.com Port: 993 Connection security: SSL/TLS Authentication method: Normal password Username: johnwgordon Hostname: smtp.mail.me.com Port: 587 Connection security: STARTTLS Authentication method: Normal password Username: johnwgordon@maccom

I tried to connect my user on my Online Accounts on Linux Mint, but it said: Authentication Failed, so i tried to open my accounts and send a message to myself. The message is sent and it appears a little window that says: Your Messages was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors. You can try or save the messages locally to Local Folders/Sent-(my e-mail name).

Same happens with Troubleshoot Mode and I don't think it's a connection error, so what is the file access error in here?

When I press send, the little box 'sending message' appears along with the blue line, but it doesn't progress beyond that even after a very long wait. SMTP settings have been checked and are correct.

Currently, Thunderbird only downloads my emails when it's open. That means that, after a week away from home, it can take 15 minutes or more for all emails to totally download. How can I make it do this in real time, as does my phone or my Cogeco Webmail?

For some reason all my emails contained in the inbox keep moving to the trash box by themselves. I have to manually move them back to the inbox. This includes read and unread messages. anyone know how to stop this? V 152.0 64 bit.
