Not receiving emails from Microsoft

Not receiving emails from Microsoft

I am setting up email for my company and have to register with various services (github, Twitter, etc.) Setting up these accounts involves receiving confirmation emails. I have received those emails from all sources EXCEPT Microsoft (to set up my developer account). I have verified that I am using the correct email address:

vinbrown@gmasterplanner.com

I am using Cloudflare to host my DNS records with the following MX records set up:

gmasterplanner.com  points to  mx.zoho.com priority 10
gmasterplanner.com  points to  mx2.zoho.com priority 20
gmasterplanner.com  points to  mx3.zoho.com priority 50

Can someone please help me fix this issue (if it's something on my end)?
