While the application does not currently have the ability to drag-and-drop files directly from Outlook into the application directly, here is a quick trick to get files from your email into the application:
- Open Outlook, File Explorer, and the application multi-file upload window. You may create a temp file in File Explorer to make it easy to locate your attachments pulled out of Outlook.
- Drag and drop the attachments from Outlook into the File Explorer window.
- Grab the selected group of files from the File Explorer Window and drag them into the application's multi-upload window.
