【问题描述】：

我们使用的是 Exchange Server 2010。我可以使用 search-mailbox cmdlet 从用户邮箱中删除会议，如下所述

search-mailbox -searchquery "kind:meetings from:$recipient" -targetmailbox $mailid -targetfolder "REPORT" -deletecontent -force

我的问题是从组织者邮箱中删除会议后如何向与会者发送取消邮件？

问候，

【解决方案1】：

你不能。搜索邮箱是一个服务器端/管理功能。取消会议是客户端/用户功能。如果要发送取消通知，则需要使用 EWS 进行普通用户会议取消。

这是一个示例，如何使用 Outlook 作为 com 对象从今天开始取消会议。

    $outlookApplication = New-Object -ComObject 'Outlook.Application'
    $namespace  = $outlookApplication.GetNamespace("MAPI")
    print("Define Start/End time for filtering existing meetings..")
    $Start = (Get-Date).AddDays(-1).ToShortDateString() + " 11:59 PM"
    $End = (Get-Date).AddDays(+1).ToShortDateString() + " 12:01 AM"
    print("Start time: " + $Start)
    print("End time: " + $End)
    print("Create meeting filter..")
    $Filter = "[MessageClass]='IPM.Appointment' AND [Start] > '$Start' AND [End] < '$End'  
    AND     [IsRecurring] = '$False'"
    print("Extract all meetings...")
    $olFolderCalendar = 9
    $Appointments = $namespace.GetDefaultFolder($olFolderCalendar).Items
    $Appointments.Sort("[Start]")
    $Appointments.IncludeRecurrences = $false
    print("Process all meeting from today..")
    foreach ($Appointment in $Appointments.Restrict($Filter) ) {
        print("Process meeeting.. Subject: " + $Appointment.Subject)
        print("Required resources: " + $Appointment.Resources)
        print("Meeting start time: " + $Appointment.Start)
        print("Meeting end time: " + $Appointment.End)
        print("Cancell meeting..")
        $Appointment.meetingstatus = 5
        # olMeeting 1   The meeting has been scheduled.
        # olMeetingCanceled 5   The scheduled meeting has been cancelled.
        # olMeetingReceived 3   The meeting request has been received.
        # olMeetingReceivedAndCanceled  7   The scheduled meeting has been cancelled but 
         still appears on the user's calendar.
        # olNonMeeting  0   An Appointment item without attendees has been scheduled. This 
         status can be used to set up holidays on a calendar.
        $Appointment.Send()
        print("Delete meeting..")
        $Appointment.Delete()
    }
