Saving outlook msg file in vb.net

I am able to save outlook msg file using Microsoft.Office.Interop.Outlook.dll

 Dim objOutlk As New Outlook.Application 'Outlook
            Const olMailItem As Integer = 0
            Dim objMail As New System.Object

            objMail = objOutlk.CreateItem(olMailItem) 'Email item
 objMail.To = "test@gmail.com'

            ''Insert your "CC" address...it can by dynamically populated
            objMail.cc = "abc@gmail.com" 'Enter an address here To include a carbon copy; bcc is For blind carbon copy's

            ''Set up Subject Line
            objMail.subject = "test msg"

         
            ''Set up your message body
            objMail.body ="just a test msg"
          

            ''Use this To display before sending, otherwise call (use) objMail.Send to send without reviewing
            objMail.Display()
            objMail.SaveAs("E:/test.msg", Outlook.OlSaveAsType.olMSG)

            ''Clean up
            objMail = Nothing
            objOutlk = Nothing

It's working in visual studio.

But now I have deployed my application to IIS but now it's not working

Please help
