To transfer Apple Mail to Outlook.com using IMAP settings, first, enable IMAP in your Apple Mail account settings. Then, configure your Outlook.com account in Apple Mail by adding it through the “Accounts” section using your Outlook IMAP server details (imap-mail.outlook.com). Once the connection is established, sync your Apple Mail folders with Outlook.com. This will allow you to transfer and access Apple Mail emails in Outlook.com without losing data. For more complex migrations, consider using the Regain Apple Mail to Outlook Converter Tool, which automates the process and ensures data integrity while moving emails to Outlook.com efficiently.
