active-directory - Outlook 2016 の署名と Active Directory

Question

Outlook の署名を作成し、Active Directory で日付 (DisplayName、Telephone、および Title) を調べるスクリプトがあります。

.docx ファイルを appdata にコピーし、html、rtf、および txt に保存するコード行があります。

#Save new message signature 
Write-Output "Saving signatures"
#Save HTML
$saveFormat = [Enum]::Parse([Microsoft.Office.Interop.Word.WdSaveFormat], "wdFormatHTML");
$path = $LocalSignaturePath+'\'+$SignatureName+".htm"
$MSWord.ActiveDocument.saveas([ref]$path, [ref]$saveFormat)

#Save RTF 
$saveFormat = [Enum]::Parse([Microsoft.Office.Interop.Word.WdSaveFormat], "wdFormatRTF");
$path = $LocalSignaturePath+'\'+$SignatureName+".rtf"
$MSWord.ActiveDocument.SaveAs([ref] $path, [ref]$saveFormat)

#Save TXT    
$saveFormat = [Enum]::Parse([Microsoft.Office.Interop.Word.WdSaveFormat], "wdFormatText");
$path = $LocalSignaturePath+'\'+$SignatureName+".txt"
$MSWord.ActiveDocument.SaveAs([ref] $path, [ref]$SaveFormat)
$MSWord.ActiveDocument.Close()
$MSWord.Quit()

Outlook 2013 では問題なく動作しますが、Outlook 2016 で実行すると、次のエラーが発生します。

Outlook 2016 の別の書式設定はありますか?

ありがとう！
