Any given Outlook user's data is not guaranteed to be accessible from a web service or web application. If the user is using POP3 or IMAP account, their data will be stored locally on their PC and cannot be read without installing a custom client application to read their Outlook data and communicate back to your web server.

If they are using an Exchange Mailbox, then you can access that data from your web server via Exchange Web Services - but you'd need to authenticate with their password (or an AD token if you have that already in your web app).
