I recently moved site from WordPress to Shopify and changed the DNS records. Address is hosted by GoDaddy. As a result, my email which is also hosted by GoDaddy (Office 365 Personal) stopped working. I added new DNS records for TXT, CNAME, and MX per the below. But, it didn’t work. Please help 
Hey,
you only need to add a A and CNAME record to your DNS Settings to connect your domain to shopify.
Do not add a new MX record. MX records are for mailing purposes. (So for your outlook).
