Migrating Apple Mail to a Microsoft 365 account on macOS manually involves configuring both accounts in the Apple Mail app, exporting Apple Mail emails to an MBOX file, and then importing them into Outlook. This process is time-consuming, especially for large mailboxes, and may result in errors like missing attachments or incomplete folder structures.
Using the iCloud Backup Tool simplifies this migration. It directly exports Apple Mail data and transfers it to a Microsoft 365 account seamlessly. This method ensures a faster, more efficient migration while preserving all emails, attachments, and folder hierarchy, avoiding the complications of the manual approach.
