从系列中删除异常

Question

我在 Outlook 中有一个系列，但有一些例外。我想做的是删除本系列中的所有例外。有谁知道是否有办法做到这一点？由于例外列表是只读的，我尝试清除重复模式并重新应用所有没有例外列表的值，如下所示：

Dim tRType As OlRecurrenceType
Dim tRPSD As Date
Dim tRPED As Date
Dim tST As Date
Dim tET As Date
Dim tOcc As Integer
Dim tInterval As Integer

tRType = oAppointmentItem.GetRecurrencePattern.RecurrenceType
tRPSD = oAppointmentItem.GetRecurrencePattern.PatternStartDate
tRPED = oAppointmentItem.GetRecurrencePattern.PatternEndDate
tST = oAppointmentItem.GetRecurrencePattern.startTime
tET = oAppointmentItem.GetRecurrencePattern.endTime
tOcc = oAppointmentItem.GetRecurrencePattern.Occurrences
tInterval = oAppointmentItem.GetRecurrencePattern.Interval

oAppointmentItem.ClearRecurrencePattern
' This save throws an error. 
'oAppointmentItem.Save

' Make this call to flip to reccurring...
oAppointmentItem.GetRecurrencePattern
oAppointmentItem.GetRecurrencePattern.RecurrenceType = tRType
oAppointmentItem.GetRecurrencePattern.PatternStartDate = tRPSD
oAppointmentItem.GetRecurrencePattern.PatternEndDate = tRPED
oAppointmentItem.GetRecurrencePattern.startTime = tST
oAppointmentItem.GetRecurrencePattern.endTime = tET
oAppointmentItem.GetRecurrencePattern.Occurrences = tOcc
oAppointmentItem.GetRecurrencePattern.Interval = tInterval

到目前为止，我对这种方法没有什么运气。一旦调用 ClearRecurrencePattern，所有数据都无法更新（或者无论如何都不会持久），这就是我尝试保存但它不起作用的原因。一定有更好的方法，但我只是想念它。

我还考虑过制作约会项目的完整副本，然后删除/重新添加，但是，如果可能的话，我想避免这种情况。

我找到了答案并将其发布在这里以防有人需要。您可以修改模式结束时间（我假设开始时间）以使其清除异常列表。下面的代码会导致从系列中删除所有异常。

Dim tEndDate As Date
Dim currentEndDate As Date
Dim dateInterval As Double
currentEndDate = oAppointmentItem.GetRecurrencePattern.PatternEndDate
tEndDate = oAppointmentItem.GetRecurrencePattern.PatternEndDate
' Add a year to the end date so we can force the exceptions to remove.
DateAdd "yyyy", 1, tEndDate
oAppointmentItem.GetRecurrencePattern.PatternEndDate = tEndDate
oAppointmentItem.GetRecurrencePattern.PatternEndDate = currentEndDate
