I bought a new PC Windows 11, installed Office 2019, but when I send email I get "outlook cannot connect to your outgoing (SMTP) email server".

I check my old computer which works, and it shows:
File / Account-Settings / Server
-Incoming / tick only “This server requires an encrypted connection”
-Outgoing / Encryption=STARTTLS and tick “My Outgoing…”, “Use same”

I applied same settings to new PC, also Windows 11, Office 2019, but I get above error.
Any suggestions?
