EWS - Link to all Calendars

Hi, I have been able to link an ASP.NET page into exchange to display meetings from the current day for a user.

What I would like to be able to do is retrieve the same info as before (all of the meetings for the current day), but instead retrieve them from all of the users.

Is this possible?

Below is my code to retrieve that information from one user.

Thanks very much

Imports Microsoft.Exchange.WebServices.Data

Partial Class Test
    Inherits System.Web.UI.Page


    Shared userEmail As String = "jsmith@mydomain.local"
    Shared userPassword As String = "theuserspassword"


    Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load


        Dim service As New ExchangeService(ExchangeVersion.Exchange2010_SP1)

        service.Credentials = New WebCredentials(userEmail, userPassword)
        service.AutodiscoverUrl("administrator@mydomain.co.uk")

        Dim foundAppointments As FindItemsResults(Of Appointment) = service.FindAppointments(WellKnownFolderName.Calendar, New CalendarView(DateTime.Now, DateTime.Now.AddDays(1)))


        For Each app As Appointment In foundAppointments
            TextBox1.Text += "Subject: " + app.Subject + vbCrLf
            TextBox2.Text += "Start: " + app.Start + vbCrLf
        Next

    End Sub


End Class
