通过Powershell从SharePoint下载文件

Question

我正试图通过PowerShell从SharePoint网站下载文件。此脚本的目标是获取SharePoint文件并将其应用于Outlook以获得员工签名。我们已经创建了我们想要的员工签名，我们只需要将这些.htm文件部署到员工设备上。我正在通过Office 365 Endpoint Manager(不再是Intune(运行此脚本，以便部署到我的最终用户。脚本将在机器上本地创建.htm文件，但当打开.htm文件时，它会将我带到网站url，而不会为我提供实际的电子邮件签名——几乎就像该命令只是复制而不是实际下载一样。关于如何添加到此脚本以从存储电子邮件签名的SharePoint网站下载相应的文件，有什么想法吗？或者还有另一个我没有想过的更简单的选择可以更好地发挥作用吗？对一些SharePoint功能和Powershell与SharePoint的通信还是有点陌生，所以请耐心等待。谢谢你的帮助。

使用以下代码来帮助构建脚本：https://github.com/marcusburst/scripts/blob/master/Powershell/Exchange/AutomaticOutlookSignature.ps1

做出了调整以满足我的需求。

我想我不久前遇到了这个问题。我认为你的脚本很好，你只需要确保你的blob存储中有一个有效的令牌。
