在 PS 脚本中处理 PSSession

Question

所以我的问题是该脚本第一次运行良好，但如果我再次尝试运行它，PSSessions 仍然处于活动状态，尽管

获取-PSSession |删除-PSSession

行。我尝试了其他方法，例如调用计算机名或实例 ID，但仍然不会关闭它们。我不确定为什么会话没有关闭，但这是阻止此脚本正常工作的最后一件事。

这也是从此处的 Microsoft 文章中制作的：https://support.microsoft.com/en-us/help/2956029/migrationpermanentexception-cannot-find-a-recipient-that-has-mailbox-g

没有理由从头开始这样做。已经有工具/插件可以为您执行此操作。

Adding Exchange Shell items to PowerShell ISE

# in the Microsoft.PowerShellISE_profile.ps1 file, add the following contents:

$psISE.CurrentPowerShellTab.AddOnsMenu.SubMenus.Add(
    "Connect to Exchange @ Contoso", {
        $ExSession  = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri 'http://exserver.contoso.com/PowerShell/' -Authentication Kerberos
        Import-PSSession $ExSession

至于这个……

Get-PSSession | Remove-PSSession

...虽然它应该可以工作，但我经常觉得这有点古怪，强制循环。

Get-PSSession | ForEach {Remove-PSSession -Id $PSItem.Id}
