Configure my DNS on Namecheap

I use MS Office 365 for email. I bought a shared namecheap hosting account for my main website. I need to have the DNS records configured so that I can use MS Office 365 for email and still have my website running from the Namecheap hosting service. Problem: Once I select the namecheap hosting DNS, my access to host records is not available. (It is available with namecheap Basice DNS) But with basic, the hosting for my website does not work. Namecheap support told me to control my DNS from cPanel, but I don't know how to do that.
