删除网站“Site-URL”时出现问题。无法删除具有子网站或某些应用程序的网站。请删除所有子网站并删除应用程序后重试。

问题：如果您尝试删除其中包含子网站的 SharePoint Online 网站，SharePoint 会抛出一条错误消息，提示
“出现问题删除网站“”。无法删除具有子网站或某些应用程序的网站。请删除所有子网站并删除应用程序后重试。“

解决方案：

基本上，SharePoint Online 告诉我们：您必须先删除所有子网站才能删除其父网站。只需点击几下即可删除子网站：

1. 导航到子网站>>转到网站设置>>单击网站操作组下的“删除此网站”链接。

2. 确认一次提示。

   

但是，当您有大量子网站（例如：50 个！）时，使用浏览器界面删除每个子网站既麻烦又耗时。所以，解决方案就是PowerShell！

使用 PowerShell 删除 SharePoint Online 中的子网站：

#Load SharePoint CSOM Assemblies
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\ISAPI\Microsoft.SharePoint.Client.dll"
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\ISAPI\Microsoft.SharePoint.Client.Runtime.dll"

#Set Parameters
$SiteURL="https://crescent.sharepoint.com/sites/Ops/us/2017"

#Get Credentials to connect
$Cred= Get-Credential
$Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($Cred.Username, $Cred.Password)

#Setup the context
$Ctx = New-Object Microsoft.SharePoint.Client.ClientContext($SiteURL)
$Ctx.Credentials = $Credentials
         
$Ctx.web.DeleteObject()
$Ctx.ExecuteQuery()
write-host -f Green "Subsite Deleted Successfully "$SiteURL

此 PowerShell 脚本删除给定站点，该站点下面没有子站点。让我们添加一些错误处理代码并将其包装在可重用函数中。以下 PowerShell 脚本递归删除站点及其所有子站点。

    }
}

#Set Parameters
