Below is a step-by-step breakdown to ensure a smooth transition from GoDaddy’s email service to Microsoft 365 from O’Brien Media:

• Sign in to Microsoft 365 Admin Center.
• Go to Setup > Domains and add your GoDaddy domain.
• Follow the steps to verify ownership by adding a TXT record in GoDaddy’s DNS settings.

• Confirm all email accounts exist in GoDaddy and note their credentials.
• Make a list of usernames and passwords, as they may be needed later for migration.

• In Microsoft 365 Admin Center, go to Users > Active users and create accounts for all 84 users.
• Assign the appropriate licenses (Microsoft 365 Business Standard, Exchange Online, etc.).

• In Microsoft 365 Admin Center, go to Setup > Domains, and update the DNS records as provided by Microsoft.
• Remove old MX records pointing to GoDaddy and replace them with Microsoft’s MX record.
• Allow some time for DNS propagation (may take a few hours).

• In Microsoft 365 Admin Center, go to Setup > Migration and start an IMAP migration.
• Select IMAP Migration and enter GoDaddy’s IMAP server details
• Upload the list of email addresses with their credentials (if required).
• Start the migration process.

• Go to Exchange Admin Center > Recipients > Migration to track the status.
• Migration time varies based on email size and number of users.

• Test sending and receiving emails in Microsoft 365.
• Ensure users can log in and access their mail.

• Once migration is complete and emails are working in Microsoft 365, delete old accounts in GoDaddy.
• Remove any unused DNS records related to GoDaddy email.
