可能的原因：
- 设置IncludeRecurrences后进行排序。
这是我在两个日期之间检索Outlook项目的PowerShell模块的代码。
还有一个小程序，用于检查更改并发送包含议程更新的电子邮件，当您无法通过移动设备访问Exchange时，该小程序将很方便。

Function Get-OutlookCalendar

<#
.Synopsis
This function returns appointment items from default Outlook profile
.Description
This function returns appointment items from the default Outlook profile. It uses the Outlook interop assembly to use the olFolderCalendar enumeration.
It creates a custom object consisting of Subject, Start, Duration, Location
for each appointment item.
.Example
Get-OutlookCalendar |
where-object { $_.start -gt [datetime]"5/10/2011" -AND $_.start -lt `
[datetime]"5/17/2011" } | sort-object Duration
Displays subject, start, duration and location for all appointments that
occur between 5/10/11 and 5/17/11 and sorts by duration of the appointment.
The sort is the shortest appointment on top.

这是在模块中调用PowerShell函数的代码：
路径：Documents \ WindowsPowerShell \ mono.ps1
Import-Module -Name Outlook\expcal.psm1 -Force
$i=0
#infinite loop for calling connect function
while(1)
{
$i = $i +1
Write-Output "Running task Get-OutlookCalendar ($i)"
Get-OutlookCalendar
start-sleep -seconds 300
}
要运行PowerShell脚本，请使用powershell.exe。要在启动时运行此程序，请在“％APPDATA％\ Microsoft \ Windows \ Start Menu \ Programs \ Startup \”上运行一个快捷方式：
