I've been living with the inability to send email from Thunderbird since early July and it has been very inconvenient. I've tried the various remedies suggested on relevant threads, to no avail. All that I can think of is to reinstall Thunderbird, but I have lots of emails saved in folders that I don't want to lose. Is there a way to reinstall Thunderbird without losing all of my saved emails?

just run the installer, but it will not fix anything other than some system integration issues. Even if you uninstall and reinstall it will still not affect the stored mail and account settings The inability to send mail is not going to be helped at all.

So perhaps what is the exact error message you see when you try and send mail?

It tries for awhile to send and then I get "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) mail.twc.com timed out. Try again." It started doing this about 6 weeks ago after years of working fine. I checked server settings, disabled anti-virus program, had email/internet provider check everything on their end. I can still receive email in Thunderbird, I just can't send. I can go online to my webmail and receive and send emails, just can't send from Thunderbird anymore.

I am not saying I have an answer, but something has changed, I think at the Time Warner/ Sectrum end of things.

I have been endeavoring for some time to get someone to run a log and supply it to determine exactly what the point of failure is. So far I have not seen one, but there are a few other spectrum customers floating around the forum with like issues.

But as your issue is only around sending. First, can you confirm that you are connecting to the internet via the TWC service. You are not on a hotspot or away on holiday or using an internet cafe for instance. Historically TWC did not allow you to send mail unless your internet connection was supplied by them. You could down load it, but their server would not allow you to connect to send mail.

If you are using their service, can you please create a log that I could view to see what is going on?

I am using the computer and Thunderbird in my home on internet provided by Spectrum and my email is provided by spectrum, so no conflict.

I'm not sure what sort of log you are asking me for. Could you please fill me in?

Thank you for your help.

I have the exact same problem after an update in November to 115.5.1 (32-bit)

Clearly a TB problem as all worked well until the update.

As with you - so very inconvenient and whilst I have posted to different sites - no workable answer.

Have you any resolutions?
