This functionality facilitates seamless access and manipulation of attachments within emails, enhancing the productivity and utility of Outlook add-ins.

However, it's important to note that this specific service is not currently available or supported within mobile applications.

This limitation poses a challenge for developers aiming to create consistent experiences across various platforms, including desktop and mobile devices.

I am reaching out to inquire about list of all JavaScript API’s that can facilitate the downloading of attachment data within Outlook add-ins.

Specifically, I am interested in APIs that can be utilized within a React.js-based Outlook add-in to retrieve attachment content from emails, ensuring compatibility across all platforms.
