将旧的公共文件夹导出到文件系统上的共享的脚本

是否有 PowerShell cmdlet 可以将公共文件夹的内容从 Exchange 2007 导出到网络上的 PST？我有大约 100 个公共文件夹需要归档到网络上的不同位置，并且想自动执行该过程。

然后还需要能够删除公共文件夹。

如果不是 PowerShell，是否有其他实用程序可以从命令行执行相同操作？

谢谢，罗布。

答案1

我相信如果没有第三方工具，您将需要使用 Outlook 来导出公共文件夹。

答案2

即使五年过去了，我还是找不到任何如何做到这一点的例子，所以我使用了 Glen Scales 出色的 EWS 和 PowerShell 博客文章来拼凑它。它针对 Exchange 2013 SP1 进行了调整，但功能非常基础，因此它也应该适用于早期版本。

您不能使用 PowerShell 将公用文件夹导出到 PST：

您可以使用以下方法进行操作：

  1. 使用 Outlook：导入/导出向导

  2. 使用第三方工具
