A small company in Canada needed to move 4 mailboxes from Namecheap Private Email to Microsoft 365 without losing any mail.
What I did: backed up all 4 mailboxes first, including every folder, so a full copy existed before anything changed. Then I verified the domain in Microsoft 365, set up the users, and migrated mail and folders in the background so nobody lost access during the move.
Cutover: switched the MX, SPF and autodiscover records, ran a final sync to catch new mail, and set up DKIM and DMARC so messages land in the inbox instead of spam.
Result: all 4 users on Microsoft 365 with their mail intact, sending and receiving tested, and Outlook set up on their computers and phones.
