使用PowerShell+EWS Managed API创建Exchange重复会议遇阻求助

错误原因说明 #

1. Microsoft.Exchange.WebServices.Data.Recurrence是抽象基类，无法直接通过New-Object实例化，必须使用其具体子类（如WeeklyPattern、RelativeMonthlyPattern等）。
2. 调用WeeklyPattern构造函数时，需传入完整参数（开始日期、重复周几、间隔周数），参数缺失会导致匹配失败。

前置准备 #

确保已正确加载EWS Managed API DLL并初始化Exchange服务：

# 加载EWS DLL
Add-Type -Path "C:\路径\到\Microsoft.Exchange.WebServices.dll"

# 初始化Exchange服务
$exchangeService = New-Object Microsoft.Exchange.WebServices.Data.ExchangeService([Microsoft.Exchange.WebServices.Data.ExchangeVersion]::Exchange2016)
$exchangeService.Credentials = New-Object Microsoft.Exchange.WebServices.Data.WebCredentials("邮箱账号", "密码")
$exchangeService.Url = New-Object Uri("https://outlook.office365.com/EWS/Exchange.asmx") # 根据Exchange环境调整URL

各类型重复会议代码示例 #

每周重复会议 #

# 创建基础预约对象
$weeklyAppt = New-Object Microsoft.Exchange.WebServices.Data.Appointment($exchangeService)
$weeklyAppt.Subject = "每周团队例会"
$weeklyAppt.Body = "每周三下午14点的同步会议"
$weeklyAppt.Start = [DateTime]"2024-05-22 14:00:00"
$weeklyAppt.End = $weeklyAppt.Start.AddHours(1)
$weeklyAppt.Location = "一号会议室"

# 设置每周重复规则：每周三、每1周重复一次，持续到2024年底
$weeklyRecurrence = New-Object Microsoft.Exchange.WebServices.Data.Recurrence.WeeklyPattern(
    $weeklyAppt.Start.Date,
    [Microsoft.Exchange.WebServices.Data.DayOfTheWeek]::Wednesday,
    1
)
$weeklyRecurrence.EndDate = [DateTime]"2024-12-31"
$weeklyAppt.Recurrence = $weeklyRecurrence

# 保存并发送邀请
$weeklyAppt.Save([Microsoft.Exchange.WebServices.Data.SendInvitationsMode]::SendToAllAndSaveCopy)

每月重复会议（每月第2个周二） #

$monthlyAppt = New-Object Microsoft.Exchange.WebServices.Data.Appointment($exchangeService)
$monthlyAppt.Subject = "月度工作汇报"
$monthlyAppt.Body = "每月第二个周二的进度汇报"
$monthlyAppt.Start = [DateTime]"2024-05-14 10:00:00"
$monthlyAppt.End = $monthlyAppt.Start.AddHours(2)
$monthlyAppt.Location = "二号会议室"

# 设置每月重复规则：每月第2个周二、每1个月重复一次，共10次
$monthlyRecurrence = New-Object Microsoft.Exchange.WebServices.Data.Recurrence.RelativeMonthlyPattern(
    $monthlyAppt.Start.Date,
    2,
    [Microsoft.Exchange.WebServices.Data.DayOfTheWeek]::Tuesday,
    1
)
$monthlyRecurrence.NumberOfOccurrences = 10
$monthlyAppt.Recurrence = $monthlyRecurrence

$monthlyAppt.Save([Microsoft.Exchange.WebServices.Data.SendInvitationsMode]::SendToAllAndSaveCopy)

每年重复会议（每年5月20日） #

$yearlyAppt = New-Object Microsoft.Exchange.WebServices.Data.Appointment($exchangeService)
$yearlyAppt.Subject = "年度客户答谢会"
$yearlyAppt.Body = "每年5月20日的客户答谢活动"
$yearlyAppt.Start = [DateTime]"2024-05-20 15:00:00"
$yearlyAppt.End = $yearlyAppt.Start.AddHours(3)
$yearlyAppt.Location = "宴会厅"

# 设置每年重复规则：每年5月20日、每1年重复一次，永久生效
$yearlyRecurrence = New-Object Microsoft.Exchange.WebServices.Data.Recurrence.AbsoluteYearlyPattern(
    $yearlyAppt.Start.Date,
    5,
    20
)
$yearlyRecurrence.NeverEnds = $true
$yearlyAppt.Recurrence = $yearlyRecurrence

$yearlyAppt.Save([Microsoft.Exchange.WebServices.Data.SendInvitationsMode]::SendToAllAndSaveCopy)
