Open Local Outlook Client with Attachments from Backend Using Frontend File Selection [closed]

I’m working on a web application where users can select files in the frontend, and those files are fetched from the backend. After selecting the files, I want the user’s local Outlook client to open with a pre-drafted email that includes the selected attachments, allowing the user to review and send the email manually.

Here’s what I’m trying to achieve:

Scenario: The user selects files in the frontend. After clicking the “Send Mail” button, the local Outlook client should open with a new email, including the files (fetched from the backend) attached.

Requirements:
The email should be opened in the user’s local Outlook client before sending (instead of being sent programmatically).

Attachments should be dynamically fetched from the backend based on the user’s selection in the frontend.

I am aware of how to send emails programmatically using the Microsoft Graph API, but I need a solution that opens the local Outlook client instead.

I’m considering whether Outlook add-ins could help, but I haven’t figured out how to pass attachments from the backend.
