How can you perform a mailbox migration to Exchange Online?

To perform a mailbox migration to Exchange Online, utilizing the Exchange Admin Center or PowerShell commands is the most effective method. This approach leverages the built-in tools provided by Microsoft, which are specifically designed to facilitate the migration process smoothly and efficiently.

The Exchange Admin Center (EAC) offers a user-friendly web interface that simplifies configuration and management tasks, including mailbox migrations. It provides wizards and options that guide administrators through the process, making it accessible even for those who may not be as familiar with scripting or command-line operations.

Additionally, PowerShell commands offer advanced users more flexibility and control. PowerShell can be particularly useful for bulk migration scenarios or when specific customization is required that might not be available through the EAC. By using PowerShell, administrators can script and automate parts of the migration process, significantly improving efficiency when dealing with large numbers of mailboxes.

This method stands out because it is specifically tailored for Exchange environments, ensuring compatibility and a streamlined process that minimizes the risk of error during migration.
