Using New Outlook on Windows for personal email, calendar, and contact management
Hi Jennifer Evans,
Since you're using New Outlook, some of the menu paths commonly referenced for Classic Outlook are not available. To help narrow down the cause, could you please check the following:
- Open Settings > Mail > Rules and review whether any rules are automatically moving or deleting messages.
- Check your Archive, Deleted Items, and Junk Email folders to see if the missing messages are being relocated rather than permanently removed.
- Sign in to Outlook on the web and verify whether the same messages are missing there as well. This can help determine whether the behavior is account-related or specific to the Outlook app.
If possible, please let me know:
- Whether entire emails are disappearing or only their attachments/files.
- The type of account you're using (Outlook.com, Microsoft 365, Gmail, or another provider).
That information will help the community provide more targeted troubleshooting steps. I look forward to your update and will be happy to assist further.
