Thunderbird Support Forum

I changed my BT email password but cannot send emails from Thunderbird. I can receive them. I receive this message - Unable to authenticate to Outgoing server (SMTP) mail.btinternet.com. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'. I have checked my outgoing server settings which are -

Description: BT Yahoo Server Name: mail.btinternet.com Port: 465 User Name: rvynerp@btinternet.com Authentication method: Normal password Connection Security: SSL/TLS

My BT email works fine for both receiving and sending so the problem is with Thunderbird outgoing mail settings

Hello, I own and operate my own business in the automotive repair sector however my direct computer knowledge is not sufficient in many cases. My issue is that my Gmail and Thunderbird is linked to send messages to my clients for estimate purposes. Incoming mail to Gmail as well as outgoing from Gmail gets copied into Thunderbird. Assuming that Thunderbird had so many emails on the screen I asked the internet on how to do a mass email delete. Now I assume "that" is the reason why all my labels/folders are now empty I can both Gmail and Thunderbird? These folders held important invoices, contact information and just important information for me to go back into should a situation require it. How do I recover all of my deleted messages in Thunderbird? Will this repopulate the folders with my missing information?? The individual who set it up for me is an expert in the field however I am unable to make any contact with him. He's not responding to any of my messages or calls. Please help. Now please remember I am very ignorant when it comes to this type of experience. Please provide me with the most elementary explanations for this recovery process. Super lament terms and instructions are extremely appreciated. Thanks. Les

Good news For some months now, I have stayed on a much earlier version of 115. Today I updated to the latest available... no issues arising so I happily conclude that Tbird is stable.

Thanks to all who are working on making this a great product.

I have changed my BT password and now can't send emails via Thunderbird. I can send them with BT though. This is the answer I get when I try to send an email -

''Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) mail.btinternet.com. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'.''

When I check my outgoing server settings I get this -

Description: BT Yahoo Server Name: mail.btinternet.com Port: 465 User Name: rvynerp@btinternet.com Authentication method: Normal password Connection Security: SSL/TLS

Can anyone help as I much prefer using Thunderbird for emails, over BT Richard P.

Hello,

I'm kicking the tires on this and the biggest obstacle for me right now is that when I view the calendar in a week view, the day starts at midnight. I would like to hide midnight to 6am.

I followed these steps, that did not work:

1. Navigate to the hamburger menu in the upper right corner. 2. Select settings. 3. In the calendar tab, I changed day starts to 6am, and day ends to 9pm.

There is no way to save this, so I assume it just works. However, when I navigate back to the calendar, nothing has changed. The day still starts at midnight.

Am I possibly looking in the wrong place? Is there a way to customize this as I've described?

Thanks for any help.

my email will go offline while in use or while other internet programs working fine and only allows "send later". sometimes comes back shortly other times can be hours later. How can I check status and bump it back online without having to shut down and lose work.

How many times per day, and over a period of how many years, will it be necessary to tell Mozilla Thunderbird Email that I DO NOT want Mozilla Thunderbird Email to:

Read, compose, send, and permanently delete all my email from Gmail

BEFORE THEY WILL STOP ASKING?

I have an issue trying to configure a secondary email account, for a non-profit I do some work for. It was ok in the past, though I recall was tricky to set up on TB a couple of years ago. But now it has ceased to function after I migrated TB profile (successfully apart from this issue) no matter what I try. I’d be grateful for any suggestions. As is the case with many non-profits, there’s little tech support, but others can use the email account ok. I think it may be a TB issue as I have been able to set up the account ok with MS new Windows Outlook app (lame, but better than Mail…low bar). I’d rather have this account on my TB client along with the others I use. And the issue is replicated on two of my PCs. TB account set up reports “can’t detect settings from host server”. I found a support thread link text, which says “The failure to detect settings is rather common where hosted domains are concerned. Mostly because everything is done to a price and most of the things around encryption are done in a halfhearted manner. As is the server setups for mail. However by faithfully copying the settings from the provider as to domains server name and ports it should work.” So I did manual configuration – copied the settings from the successful Outlook set up, but no dice – all I get is server time out message. Settings are: IMAP server: mail.XXXX.org.uk Port 993 Security SSL/TLS [earlier working settings were STARTTLS port 143] SMTP server: mail.XXXX.org.uk Port 465 Security SSL/TLS [[earlier working settings were STARTTLS port 587] And using Normal Password for both; I tried Autodetect too but no good. I’ve see a suggestion that turning off the firewall (Norton) might work, but I’m reluctant to do that and doesn’t seem to make sense that would cause the issue. I found another suggestion that apparently works for some people - leaving password blank on setup. https://support.mozilla.org/en-US/questions/1399690. Before I try, are there any other suggestions or ideas? Trivial matter in the long run, but bugging me. Thanks

After recent update to Thunderbird 115.11.0, I can't send emails through my hotmail smtp server.

Error message: Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp-mail.outlook.com timed out. Try again.

I read the Thunderbird update for 2024 information that recommends changing Normal Password to OAuth, but OAuth is not an option on the drop down list of methods. (see attached)

How do I fix this? Thanks

I've been getting error messages when I send emails using thunderbird about server timing out. As a last resort I tried removing all accounts, and just set it up again. But then I started getting the error message during manual configuration step "Thunderbird failed to find the settings for your email account". I've already tried creating a new profile I'm still getting the same error.

here's the manual configuration I'm working with Incoming: IMAP, port 993, SSL/TLS, Normal password Outgoing: port 587, STARTTLS, Normal password

our team uses GoDaddy for email domains - not sure if that's relevant or not. other teammates have been able to set it up successfully. Same configuration, account and password.

Thunderbird seems to be hung up in a circular reference. It continues to download 1 of 2 and 2 of 2 repetitively, nonstop. This is continues process without ceasing. It seems be slowing do the whole system.

Each time I open Thunderbird email, a page on firefox opens requesting a donation. This has been going on for weeks. I reached out to Thunderbird, and all suggestions have failed to resolve the problem. Most recently I was instructed to submit the problem here. I hope this is sufficient for requesting assistance. I would like to forward our list of communications and cannot discover a method to do so. If you send me an email address, I can give all that information. Thanks, Norma Bauer cabauer@northlink.com

For some reason now, every time I go to type a response to an e-mail, the program loads hundreds of lines of text below my earlier sent message. Need help as to how to fix this problem ?
