The easiest way to export iCloud Mail to Outlook on Windows is to avoid manual IMAP syncing and use a direct export approach. While IMAP can connect iCloud to Outlook, it often causes slow syncing, missing folders, or skipped attachments especially with large mailboxes.

A simpler method is to export iCloud Mail into an Outlook PST file using a dedicated MailConverterTools iCloud Mail export tool. This approach downloads all emails at once, keeps the original folder structure intact, and lets you open the PST file directly in Outlook on Windows. It’s faster, more reliable, and works well for bulk emails without data loss.
