Migrating corporate emails to Microsoft 365 is a fundamental milestone for enterprise security and professionalism. Here is the exact roadmap used by Prydelix engineers to execute zero-downtime migrations.
Step 1: Domain & DNS Preparation
Verify your domain ownership by adding TXT verification records to your DNS provider (Cloudflare, GoDaddy, Namecheap) without changing active MX records.
Step 2: User Account Creation & License Allocation
Create user mailboxes in the Microsoft 365 Admin Center and assign appropriate license tiers (e.g. Business Basic or Business Standard).
Step 3: IMAP Batch Synchronization
Initiate cloud-to-cloud IMAP synchronization to mirror all historical inbox, sent, and folder emails from your existing cPanel mail server to Microsoft 365.
Step 4: MX Cutover & Outlook Configuration
Switch your MX records to point to Microsoft servers (`yourdomain-com.mail.protection.outlook.com`) and configure 2-Factor Authentication (MFA) for all employees.
