Microsoft 365 setup for new Business/organization

Hello everyone,

I recently purchased a domain for Business mail from duhost.co.tz, and I have already hosted it. The main purpose of acquiring this domain is to use it for Microsoft 365 emails for seamless communication within my organization, allowing my staff members to easily connect with each other. Could you please guide me on how to set up this communication system using Microsoft 365?

Thank you in advance for your assistance!"
