Create DNS records at any DNS hosting provider for Office 365 concern
I am upgrading Ex 2010 to Office 365 using Exchange Hybrid deployment. I am going to create DNS records at any DNS hosting provider for Office 365. However, I am concerning that if I point our public-facing MX record to Exchange Online, instead of our on-premises Exchange server. It would change our actual mail routing.
Could you please verify it and give me some info about it?
