我正在尝试编写PowerShell代码来创建Outlook规则来移动电子邮件。

注意我没有访问服务器的权限，因此New-InboxRule等*-InboxRule插件不可用。

PowerShell和Outlook之间的COM互操作有些不稳定，因为它在C#中工作，但PowerShell中的相同代码却不工作。
C#代码：

Microsoft.Office.Interop.Outlook.Application outlook = null;

try
{
    outlook = (Microsoft.Office.Interop.Outlook.Application)System.Runtime.InteropServices.Marshal.GetActiveObject("Outlook.Application");
}
catch
{
}

if (outlook == null)
{
    outlook = new Microsoft.Office.Interop.Outlook.Application();
}

var inbox = outlook.Application.Session.GetDefaultFolder(Microsoft.Office.Interop.Outlook.OlDefaultFolders.olFolderInbox);
var oMoveTarget = inbox.Folders["MoveTarget"];

// debugging
Console.WriteLine(inbox.FolderPath.ToString());
Console.WriteLine(oMoveTarget.FolderPath.ToString());

var rules = outlook.Session.DefaultStore.GetRules();
Console.WriteLine(string.Format("There are {0} rules", rules.Count));

var name = string.Format("Rule {0}", DateTime.Now.ToString("yyyyMMdd_HHmmss"));
var rule = rules.Create(name, Microsoft.Office.Interop.Outlook.OlRuleType.olRuleReceive);

// conditions
rule.Conditions.From.Recipients.Add("John Smith");
rule.Conditions.From.Recipients.ResolveAll();
rule.Conditions.From.Enabled = true;

// actions
rule.Actions.MoveToFolder.Folder = oMoveTarget;
rule.Actions.MoveToFolder.Enabled = true;
rules.Save(true);

• 完全相同 *（除了语言语法）PowerShell代码：

try
{
    $outlook = [Runtime.InteropServices.Marshal]::GetActiveObject("Outlook.Application");
}
catch
{
}

if ($outlook -eq $null)
{
    $outlook = New-Object -ComObject Outlook.Application
}

$inbox = $outlook.Application.Session.GetDefaultFolder([Microsoft.Office.Interop.Outlook.OlDefaultFolders]::olFolderInbox);
$oMoveTarget = $inbox.Folders["MoveTarget"];

# debugging
[Console]::WriteLine($inbox.FolderPath.ToString());
[Console]::WriteLine($oMoveTarget.FolderPath.ToString());

$rules = $outlook.Session.DefaultStore.GetRules();
[Console]::WriteLine([string]::Format("There are {0} rules", $rules.Count));

$name = [string]::Format("Rule {0}", [DateTime]::Now.ToString("yyyyMMdd_HHmmss"));
$rule = $rules.Create($name, [Microsoft.Office.Interop.Outlook.OlRuleType]::olRuleReceive);

# conditions
$rule.Conditions.From.Recipients.Add("John Smith");
$rule.Conditions.From.Recipients.ResolveAll();
$rule.Conditions.From.Enabled = $true;

# actions
$rule.Actions.MoveToFolder.Folder = $oMoveTarget;
$rule.Actions.MoveToFolder.Enabled = $true;
$rules.Save($true);

PowerShell代码失败：

One or more rules cannot be saved because of invalid actions or conditions.
At line:1 char:1
+ $rules.Save($true);
+ ~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : OperationStopped: (:) [], COMException
    + FullyQualifiedErrorId : System.Runtime.InteropServices.COMException

经过进一步调查，它是由这条线引起的，这条线没有做任何事情：

$rule.Actions.MoveToFolder.Folder = $oMoveTarget;

当我运行C#等效程序时，如果我立即查看该属性，它就 * 被 * 设置了。
在PowerShell中，它什么也不做。
