Attempting to install Thunderbird on an additional desktop using same address as my original computer has. That was my question:

Who is your email provider?

Have you compared all account settings, not just the email and password?

Here's my answer to those questions: "Authentication error" "probably wrong configuration, username or password."

My email provider is MTA (Matanuska Telephone Association) Yes, I currently use Thunderbird in my other desk top and it works fine.

I have used Thunderbird as my mail client for many years on both my Windows workstation and my Windows laptop. My ISP is Spectrum. All of a sudden, today, Thunderbird has stopped sending outgoing emails from my workstation. I get a message telling me that Thunderbird can't connect with the server. Outgoing email seems to work fine on the laptop, as well as on Spectrum's own Webmail interface. I think I'm getting all my incoming messages, although it's hard to know that for sure. Both machines are running Windows 11. I haven't changed any configurations. What can I do to get Thunderbird to function correctly on my workstation? Thank you.

I want to use thunderbird on a Windows 11 laptop. Tell me how to connect Thunderbird to send and receive emails from email account, jds@sefcik.net, hosted at smartmail.buz.net.

I just replaced my WiFi router and was able to get 5 messages after new network set up, but now it can't connect to outgoing or incoming mail server.. I double checked all my setting with Spectrum and all looks good, but won't connect.

I want to change the default download protocol accessing the mail server from imap to pop3. I went into the account settings & changed the default selection from imap to pop3. But the change does not take effect. Tbird still accesses the server using the imap protocol.

I have seen this problem with roadrunner listed in the forum but my situation is a bit different. Neither my wife or I can send or receive roadrunner emails with different machines. She uses a Mac (sonoma 14.8.7), up to date, I use Linux Mint ver 22. We also have iPhones and iPads. none of these units send or receive emails for the last 24 hrs but all worked just fine before. Spectrum says it our problem not theirs. The tech person at Spectrum said they partner with Thunderbird but they did not know of any changes made.

I have changed passwords used different routers and anything I can think of to connect but the devices now all time out when trying to connect.

I upgraded my Fedora nad I think that Thunderbird 149 came with that upgrade. I cannot send mails. Ctrl+enter has no reaction. Downgraded to 148 and everyhing is fine. |<

I'm a longtime Thunderbird user. Today, it stopped working to send messages. (I can still receive messages OK.) When I try to send, it does the spell-check, but then doesn't do anything. The message remains open but unsent. In case it's helpful, my account info says IMAP mail server, SSL/TLS connection security, OAuth2 authentication,

I have been unable to send emails for several weeks and keep getting the following error message: sending of message failed The message could not be sent because connecting to the outgoing server (SMTP)smtp.1und1.de failed. The server may be unavailable or is refusing SMTP connections. Please verify that your outgoing server (SMTP) settings are correct and try again.

My settings have not been changed so I am wondering what has changed and how i can correct it. My computer knowledge and ability is very limited so please bear theis in mind when offering advice and solutions. Thank you.
