Question

使用System.Management.Automation（v。10.0.10586）我可以从Windows应用程序成功执行Exchange Online PowerShell命令，但是我需要从ASP.NET应用程序执行该命令。尝试在Web应用程序中打开运行空间时遇到“访问被拒绝”错误，除非我让Web应用程序的应用程序池在本地服务等帐户下运行。有没有一种方法可以在不向Web应用程序授予此类扩展权限的情况下进行？

Microsoft建议将Exchange用户添加为管理员角色，但这不是我的问题，因为我可以使用Windows应用程序和相同的Exchange凭据（https://support.microsoft.com/en-za/help/2905767/access-is-denied-error-when-you-connect-to-exchange-online-by-using-re）执行PowerShell命令。

我也尝试过微软建议在代码中模拟特定用户的建议，但这似乎行不通（https://support.microsoft.com/en-us/help/306158/how-to-implement-impersonation-in-an-asp-net-application）。

        Dim userName As String = ConfigurationManager.AppSettings("ExchangeUserName")
        Dim password As String = ConfigurationManager.AppSettings("ExchangePassword")
        Dim securePassword As System.Security.SecureString = New System.Security.SecureString()
        For Each c As Char In password
            securePassword.AppendChar(c)
        Next
        Dim credentials As PSCredential = New PSCredential(userName, securePassword)
        Dim connection As WSManConnectionInfo = New WSManConnectionInfo(New Uri("https://outlook.office365.com/powershell-liveid"), "http://schemas.microsoft.com/powershell/Microsoft.Exchange", credentials) With {
                .AuthenticationMechanism = AuthenticationMechanism.Basic,
                .SkipCACheck = True,
                .SkipCNCheck = True,
                .SkipRevocationCheck = True,
                .NoEncryption = False,
                .MaximumConnectionRedirectionCount = 4
            }
        Using runSpace As Runspace = RunspaceFactory.CreateRunspace(connection)
            runSpace.Open()
        End Using

该过程在runSpace.Open（）处失败，并显示以下错误：

System.Management.Automation.Remoting.PSRemotingTransportException：连接到远程服务器exchangeserver.admin.com失败，并显示以下错误消息：访问被拒绝。有关更多信息，请参见about_Remote_Troubleshooting帮助主题。
