通过 Powershell 从 SharePoint 下载文件

Question

我正在尝试通过 PowerShell 从 SharePoint 网站下载文件。此脚本的目的是获取 SharePoint 文件并将其应用于 Outlook 以供员工签名。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）运行此脚本以部署到我的最终用户。该脚本将在机器上本地创建 .htm 文件，但是当打开 .htm 文件时，它会将我带到站点 url，而不是向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 站点下载相应文件的任何想法？或者是否有另一个更简单的选择，我没有考虑过它可以更好地工作？对一些 SharePoint 功能和让 Powershell 与 Sharepoint 通信仍然有点新，所以请多多包涵。感谢您的帮助。

使用此代码帮助构建脚本：https://github.com/marcusburst/scripts/blob/master/Powershell/Exchange/AutomaticOutlookSignature.ps1

进行调整以帮助满足我的需求。

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。
