通过Powershell从SharePoint下载文件

问题描述

我正在尝试通过PowerShell从SharePoint网站下载文件。该脚本的目的是获取SharePoint文件并将其应用于Outlook以获取员工签名。我们已经创建了所需的员工签名，我们只需要将这些.htm文件部署到员工设备即可。我正在通过Office 365端点管理器（不再是Intune）运行此脚本，以部署到我的最终用户。脚本将在计算机上本地创建.htm文件，但是打开.htm文件时，它将带我到站点URL，没有为我提供实际的电子邮件签名-几乎就像命令仅在复制而不是在实际下载一样。关于如何添加到此脚本以从存储电子邮件签名的SharePoint网站下载相应文件的任何想法？还是我没有想到的另一个更简单的选择会更好？对于某些SharePoint功能还是新的功能，并且使Powershell与Sharepoint进行通信，所以请耐心等待。谢谢您的帮助。

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

进行调整以满足我的需求。

解决方法

我想我前一段时间遇到了这个问题。我认为您的脚本很好，您只需确保Blob存储中有一个有效的令牌即可。
