PowerShell Script to Simulate Outlook Web Access URL User Logon

  • Artikel

Recently I came across with a requirement to do user logon synthetic transaction on Outlook Web Access URL and capture its performance. This can be accomplished using Invoke-WebRequest PowerShell command let. The command let returns form elements which needs to be filled with username and password and the login page is invoked with the post data. The output is analyzed for successful login and logon results are returned.
