是否有 PowerShell cmdlet 可將公用文件夾的內容從 Exchange 2007 導出到網路上的 PST？我有大約 100 個公用文件夾需要歸檔到網路上的不同位置，並且希望自動化該過程。

然後還需要能夠刪除公用文件夾。

如果不是 PowerShell，是否有其他實用程序可以從命令行執行相同的操作？

謝謝，羅伯。

我相信如果沒有第三方工具，您將需要使用 Outlook 來導出公用文件夾。

即使五年過去了，我也找不到任何關於如何做到這一點的例子，所以我使用 Glen Scales 出色的 EWS 和 PowerShell 部落格文章來拼湊這些。它針對 Exchange 2013 SP1 進行了調整，但功能非常基本，因此它也應該適用於早期版本。
