I recently switched from macOS to a Windows PC and now need to move my email data to Microsoft Outlook on Windows. My emails are currently stored in a Mac-based email client (like Apple Mail or another macOS email app), and Outlook on Windows does not support these file formats directly. I am worried about issues such as missing emails, broken folder structure, attachments not opening, and data corruption during the migration. Manual methods seem complicated and risky for large mailboxes. What is the safest and most reliable way to perform a cross-platform email migration from macOS to Windows Outlook while preserving emails, folders, and attachments?
