Because of a windows 10 crash, I had to reinstall Thunderbird on my main computer. Downloaded and installed v. 115.1. Settings and data were migrated OK from my laptop, except that the new install cannot connect to the server either to receive or send. It will also not save my password. I know this is not a server problem, because Thunderbird on my laptop has no problem connecting. Thanks, Michael

Which server/ISP?

Server is Bluehost -- but another Thunderbird installation on another computer works as it should, so it is not a server problem.

I'm sorry to hear you're having trouble with Thunderbird after the Windows 10 crash. Since your laptop's Thunderbird is connecting fine, it's likely an issue specific to the new installation. Let's try a couple of things. First, ensure that your antivirus or firewall isn't blocking Thunderbird's connection. Sometimes security software can interfere. Also, make sure you have the correct server settings: incoming (IMAP/POP3) and outgoing (SMTP) server addresses and ports. If Thunderbird isn't saving your password, it might be due to a corrupted profile. Try creating a new profile by launching Thunderbird with the command "thunderbird.exe -P" (without quotes) in the Run dialog. This might help resolve the password-saving issue.
