disable outgoing encryption for smtp

I need to disable the encryption of outgoing mails on smtp however unable to locate the options in tools which outlook usually has. Could you please help…

Hi Soham,
all encryption settings are in Tools > Settings > Mail > Certificates where you can set up your security profiles.
Or you can turn off/on encryption for individual mails by clicking the little lock icon in the menu bar above the email header when writing the new message.

Best regards,
Olivia
