Drag and Drop Email from New Outlook to Web File Upload Dialog Not Working

Dear @Saul_F,

Thank you for reaching out to Microsoft Q&A forum.

I understand you’re experiencing an issue with dragging and dropping emails in the New Outlook.

From my research, the core issue is that the New Outlook is built on a web-based framework (WebView2/React) rather than the legacy architecture used by Classic Outlook. Because of this change, direct drag-and-drop integration with certain system and web-based file upload dialogs behaves differently than it did in Classic Outlook.

Until a direct bridge is built between the WebView2 container and the system’s file handler, here are the most reliable options currently available:

1.The "Two-Step" Drag

This issue can be bypassed by using your desktop or a local folder as an intermediary.

1. Drag the email from New Outlook to your Windows Desktop or a folder.
2. New Outlook will save it as an .eml file (note that Classic used .msg).
3. Drag that .eml file from your desktop into the web-based upload dialog.

2.Using the "Save As" Command

1. Open the email you wish to upload.
2. Click the More actions (...) menu in the top right.
3. Select Save as. Select Save as EML or MSG. This will download the email to your "Downloads" folder as a file, which can then be uploaded to any web dialog.
