将多个邮箱添加到一个用户时，无法对参数“ Identity”错误进行参数转换

Question

我正在尝试从MS Exchange Powershell模块中的CSV文件添加多个邮箱，但是我收到以下错误：

Cannot process argument transformation on parameter 'Identity'. Cannot 
convert value "@{identity=sharedmailbox@mail.com}" to type
"Microsoft.Exchange.Configuration.Tasks.MailboxIdParameter".
Error: "Cannot convert the "@{identity=sharedmailbox@mail.com}" value of
type "Deserialized.System.Management.Automation.PSCustomObject" to type
"Microsoft.Exchange.Configuration.Tasks.MailboxIdParameter"."
    + CategoryInfo          : InvalidData: (:) [Add-MailboxPermission], ParameterBindin...mationException
    + FullyQualifiedErrorId : ParameterArgumentTransformationError,Add-MailboxPermission
    + PSComputerName        : outlook.office365.com

在下面您可以看到脚本：

SELECT V.X.value('(RequestCessationYes/@value)[1]','varchar(5)') AS [value]
FROM (VALUES(CAST('<RequestCessationYes value="false" />' AS xml)))V(X);
