在 Windows 上使用 Classic Outlook 進行個人電子郵件、行事曆與聯絡人管理
Hi there, Morris! This is Marc, and thanks for reaching out.
Unfortunately, Microsoft only retains email data in your Outlook/Hotmail account for a limited time if the account has been inactive. If you haven’t signed in since 2016, it’s likely that older messages were automatically deleted as part of Microsoft’s data retention policy. Emails from before 2019 may no longer be recoverable, especially if the account remained inactive for multiple years.
Best,
