Send email via MS Outlook

My current situation is

I’m using PHP 7.3.8 (Localhost),
all outgoing ports are blocked (gmail 25,465,587, hotmail etc etc)
I want to use Kanboard to connect to my own microsoft Outlook so I can send email from my company email address. Please help if possible, thank you!

Outlook is a mail client, you can’t connect to that. Use the settings from your mail client to configure php to send to our corporate mailserver (microsoft exchange supports smtp). If your mailserver is also in the cloud and that port is also blocked, then you’ll need to talk to someone to open up the firewall or find an internal mailserver to use.
