DNS Setup

Hey guys hope you are all doing great,

I recently just bought a few domains with the microsoft license via godaddy directly. I've setup my warm up on instantly.ia. Half of my mail got rejected with this error:

Remote server returned '550 5.7.708 Service unavailable. Access denied, traffic not accepted from this IP.

Is it relied to my spf? Because originally the spf in godaddy is v=spf1 include:secureserver.net -all. But i tought that since it's a microsoft liscense, i changed it to v=spf1 include:spf.protection.outlook.com -all. Am I in the wrong for doing this? Should i have left it as original with the godaddy server?

Is my spf the reason some of my warm up mails rebounce or is it simply because those are new domains and its normal?

Thank you
