New-ManagementRoleAssignment–name:impersonationAssignmentName–Role:ApplicationImpersonation–User:serviceAccount
通过以上命令 在Exchange2013,2010下都可以给所有用户配置模拟，但是在2007下却不行，请问2007下该如何配置呢？
2007下执行以上命令报错如下：
The term 'New-ManagementRoleAssignment' is not recognized as a cmdlet, function
, operable program, or script file. Verify the term and try again.
