Migrate email from Bluehost to Office 365

As organizations grow, their communication requirements become more complex prompting the need for a more advanced and scalable email platform. Many organizations initially host both their website and email services with providers like Bluehost, GoDaddy, or HostGator, taking advantage of bundled packages and ease of management. While this setup offers convenience, it often falls short in terms of scalability, collaboration tools, and enterprise-grade features. That’s why more businesses are choosing to retain their current website hosting while migrating email services to Microsoft Office 365. However, transferring emails, attachments, and mailbox structure between platforms is not without challenges. A well-planned migration, backed by a reliable tool, is essential to ensure data integrity and minimize downtime

   6. Inform Users and Stakeholders : Notify your team and other stakeholders about the migration plan, expected timelines, and any temporary access limitations. Proper communication helps reduce confusion.
   7. Select and Assign Office 365 Licenses : Choose the appropriate Microsoft 365 plan based on your organization’s needs and assign licenses to each user mailbox before the migration.
