SharePoint Online：PowerShell 更改所有网站的访问请求电子邮件

要求：在 SharePoint Online 中更改访问请求电子邮件。

PowerShell 在 SharePoint Online 中更改网站集的访问请求电子邮件：

访问请求允许用户请求访问 SharePoint 网站或网站集的权限。默认情况下，访问请求会发送到网站所有者的电子邮件地址。但是，您可能希望将此电子邮件地址更改为其他电子邮件地址或组。本文将指导您完成在 SharePoint Online 中更改访问请求电子邮件的步骤。

让我们使用 PowerShell 设置 SharePoint Online 网站集的访问请求电子邮件：

#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"

Function Set-SPOAccessRequestEmail([String]$SiteURL, [String]$AccessReqEmail)
{  
    Try{
        #Setup the context
        $Ctx = New-Object Microsoft.SharePoint.Client.ClientContext($SiteURL)
        $Ctx.Credentials = $Credentials

        #Get the Web and Sub Sites
        $Web = $Ctx.Web
        $Ctx.Load($Web)
        $Ctx.Load($web.AllProperties)
        $Ctx.Load($Web.Webs)
        $Ctx.ExecuteQuery()
 
        #Check if the web has unique permissions
        $Web.Retrieve("HasUniqueRoleAssignments")
        $Ctx.ExecuteQuery()

        If($Web.HasUniqueRoleAssignments -eq $true)
        {
            #Set Access request Email
            $Web.RequestAccessEmail = $AccessReqEmail
            $Web.Update()
            $Ctx.ExecuteQuery()
            Write-Host -f Green "Access Request Email Updated for the Site:" $($SiteURL)
        }
        Else
        {
            Write-Host -f Yellow "Site '$($SiteURL)' is inhering Permissions from the Parent"
        }

        #Iterate through each subsite of the current web
        ForEach ($Subweb in $Ctx.Web.Webs)
        {
            #Call the function recursively 
            Set-SPOAccessRequestEmail -SiteURL $Subweb.url -AccessReqEmail $AccessReqEmail
        }
    }
    Catch {
        write-host -f Red "Error Updating Access Request Email!" $_.Exception.Message
    }
}
