SharePoint Online：使用 PowerShell 禁用警报

要求：在 SharePoint Online 中禁用警报！

如何在 SharePoint Online 中禁用警报？

曾经想要暂时禁用 SharePoint Online 列表或库的警报吗？尤其是那些部署了工作流程或事件接收器的项目 - 因为添加项目可能会触发警报电子邮件？嗯，无法从 SharePoint Online 用户界面禁用警报。 （但是，您可以删除警报！）。但有个好消息：您可以使用 PowerShell 禁用警报！这篇博文将向您展示如何使用 PowerShell 在 SharePoint Online 中禁用警报。

PowerShell 禁用用户的所有警报：

SharePoint Online 允许用户在列表、库和其他对象上设置警报，以便在更新时接收通知。但是，有时您可能需要禁用特定列表、库或站点的警报。在本文中，我们来看看如何在 SharePoint Online 中禁用警报。

让我们禁用给定 Web 中特定用户的所有警报 - SharePoint 警报的范围为 Web 对象！

#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"
   
#Config Parameters
$SiteURL= "https://crescent.sharepoint.com"
$UserID="[email protected]"

#Setup Credentials to connect
$Cred = Get-Credential
$Cred = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($Cred.UserName,$Cred.Password)
 
Try {
    #Setup the context
    $Ctx = New-Object Microsoft.SharePoint.Client.ClientContext($SiteURL)
    $Ctx.Credentials = $Cred
   
    #Get All Alerts of the User
    $User = $Ctx.Web.EnsureUser($UserID)
    $Ctx.Load($User)
    $Ctx.Load($User.Alerts)
    $Ctx.ExecuteQuery()

    #Loop through each alert
    Write-host "Total Alerts Found:"$User.Alerts.Count
    ForEach($Alert in $User.Alerts)
    {
        #Check the Alert Status
        If($Alert.Status -ne "Off")
        {
            #Disable the Alert
            $Alert.Status="Off"
            $Alert.UpdateAlert()
            $Ctx.ExecuteQuery()
            Write-host -f Green "Alert '$($Alert.Title)' is disabled on $($Alert.AlertType)"
        }
        Else
        {
            Write-host -f Yellow "Alert '$($Alert.Title)' is already disabled on $($Alert.AlertType)!"
        }
    }
}
Catch {
    write-host -f Red "Error Disabling User Alerts!" $_.Exception.Message
}

要重新打开警报，请使用以下命令：

 ForEach($Alert in $User.Alerts)
    {
        #Check the Alert Status
        If($Alert.Status -eq "Off")
        {
            #Enable the Alert
            $Alert.Status="On"
            $Alert.UpdateAlert()
            $Ctx.ExecuteQuery()
            Write-host -f Green "Alert '$($Alert.Title)' is Enabled on $($Alert.AlertType)"
        }
        Else
        {
            Write-host -f Yellow "Alert '$($Alert.Title)' is already Enabled on $($Alert.AlertType)!"
        }
    }

    $Ctx.Credentials = $Cred
   
    #Get All Alerts from the Web

    $Ctx.Load($List)
    $Ctx.ExecuteQuery()

    #Loop through each alert of the web and get List alerts

    {
        #Get the List and User of the Alert
        $Ctx.Load($Alert.User)
        $Ctx.Load($Alert.List)
        $Ctx.ExecuteQuery()
        $AlertUser = $Alert.user.Title
        
        #Filter the specific List Alerts from web alerts
        If($Alert.List.ID -eq $List.ID)
        {
            #Check the Alert Status
            If ($Alert.Status -ne "Off")
