Building ASP.NET application to access user’s mailbox by using EWS RRS feed

  • Question

  • Hello,

    I am building an application that uses windows authentication to authenticate users and need to access logged-in user’s mailbox on behalf of the user by using EWS.

    One option is to use the procedure explained in the following article to configure impersonation for a service account, so the application can impersonate all users:

    Configuring Exchange Impersonation (Exchange Web Services):

    The problem is that granting the services accounts to access all mailboxes is a big security concern in our organization.

     Is there any other option that let my application code work on logged-in user’s mailbox? I am asking because I know OWA web application can access users’ mailbox in single sign on scenarios and I wonder how my application do the same thing.

    Thank you,
