Problem since Win 10 upgrade: won't connect with server

I have 3 accounts on Thunderbird; been working good. Upgraded to Win 10 and the default account won't send or receive. I get a message saying the server id disconnected. My cell phone receives emails from this account fine.

Any suggestions?

If I delete the account do all my saved messages go away?

Thanks, Dave
