Microsoft 365 开发：如何通过脚本更换SharePoint Online网站集的管理员

我们都知道如果更换某个SharePoint Online Site Collection的Admin，可以通过在管理中心页面上更换，如下所示：

但如果将现有网站集管理员替换为租户中所有网站集的新管理员？那么如果你订阅中有数百个Site Collection的话，通过SharePoint Center Admin更改网站集管理员将是一项耗时且繁琐的任务。

今天给大家分享一下通过Power Shell来替换网站集管理员。

Import-Module Microsoft.Online.Sharepoint.PowerShell -DisableNameChecking
$TenantAdminURL = "https://MVPtrainingcn-admin.sharepoint.com"
$RemoveAccount="Byronliu@MVPtrainingcn.onmicrosoft.com"
$AddAccount = "Daniel@MVPtrainingcn.onmicrosoft.com"
Try {
    Connect-SPOService -url $TenantAdminURL -credential (Get-Credential)
    $Sites = Get-SPOSite -Limit ALL
    Foreach ($Site in $Sites)
    {
        Write-host "Scanning site Collection:"$Site.Url -f Cyan
        Try {
            $Admin = Get-SPOUser -Site $Site.Url -Limit All | Where {$_.IsSiteAdmin -eq $true} | Where {$_.LoginName -eq $RemoveAccount }
            If($Admin -ne $Null)
            {           
                Write-host "Add SC Admin to:"$Site.URL -f Yellow -NoNewline
                Set-SPOUser -site $Site -LoginName $AddAccount -IsSiteCollectionAdmin $True| Out-Null
                Write-host " Finished!" -f Green
                Write-host "Remove SC Admin from:"$Site.URL -f Yellow  -NoNewline
                Set-SPOUser -site $Site -LoginName $RemoveAccount -IsSiteCollectionAdmin $False | Out-Null
                Write-host "Finished" -f Green      
            }
        }
        Catch {
            write-host -f Red "Replace SC Admin!" $_.Exception.Message
        }
    }
}
Catch {
    write-host -f Red "Error:" $_.Exception.Message
}

注意：确保运行这些PowerShell脚本的帐户具有Tenant中所有网站集的网站集管理员权限，否则，您可能会遇到问题：
