Unable to create an outbound smtp server.

Your doomsday approach will likely achieve exactly nothing. It does have an effect with Microsoft products that rewrite their registry entries when you reinstall and they store everything in the Registry. It does nothing for Thunderbird because it largely does not use the registry at all.

Now, I do not have version 155, but I do have a daily build of 158. When I click the add button for an SMTP server I get this dialog.

Do you get to that point?

I have no idea why there would not have been an outgoing server added when the account was initially added. That is generally what normally happens. So make sure there is nothing in the list of SMTP servers that I have included in the background.

Thanks for the reply Matt

I get to the add server screen but, after adding Greenby data, cannot get past that point. The only servers I can select are Outlook and Gmail.

So what happens when you click save? Open the error console (ctrl+Shift+J) clear it and press save on the completed details.

What shows then in the error console? I would assume some sort of error if it does not add!

Matt,

Error log shown in attachment. At last an indication of a problem

BTW . Google/AI suggested deleting The Thunderbird profile.ini file to remove all user data and set Thunderbird back to as just downloaded. Could this help?

Google/IA often isn't correct.

This solution worked. BUT I had to remove user data directory, uninstall Thunderbird, then reinstall Thunderbird.

Thanks Wayne

Thanks for posting your results.

FWIW reinstall rarely helps solve anything. I suspect in your case it was unnecessary, and redoing the profile was all that was needed.
