我正在尝试编写一个宏,该宏将通过 Outlook 中的一个文件夹,根据一些复杂的标准为某些项目分配保留标记 ( docs )。
我不知道如何在 VBA 中做到这一点。到目前为止,我已经了解到邮件项目具有一些与保留相关的属性(PidTagPolicyTag
(文档)等),但我仍然不知道如何正确处理它们。
与这些一起使用的一些例子是什么?
以下是使用 Outlook VBA 将保留标记应用于邮件的示例:
Option Explicit
Private Sub Application_Startup()
Const retPolicy7Y As String = "C16486BDBB1B384C9BDE0C2479537191" 'Document Retention - 07 Years (7 years)
Const retPeriod As Long = 2555 '7*365 days
Dim mapi As NameSpace, sentItems As Items, cutOffDate As Date
Dim i As Long, pa As PropertyAccessor, p As Variant, isEqual As Boolean, msgDate As Variant
Set mapi = GetNamespace("MAPI")
Set sentItems = mapi.GetDefaultFolder(olFolderSentMail).Items
sentItems.Sort "SentOn", True
cutOffDate = Now - 14
For i = 1 To sentItems.Count
If sentItems(i).SentOn <= cutOffDate Then
Exit For
End If
Set pa = sentItems(i).PropertyAccessor
p = Empty
On Error Resume Next
p = pa.GetProperty("http://schemas.microsoft.com/mapi/proptag/0x30190102") 'Get PR_POLICY_TAG
On Error GoTo 0
If IsEmpty(p) Then
isEqual = False
ElseIf pa.BinaryToString(p) <> retPolicy7Y Then
isEqual = False
Else
isEqual = True
End If
If Not isEqual Then
msgDate = Empty
On Error Resume Next
msgDate = pa.GetProperty("http://schemas.microsoft.com/mapi/proptag/0x0E060040") 'Get PR_MESSAGE_DELIVERY_TIME
On Error GoTo 0
If IsEmpty(msgDate) Then
msgDate = pa.GetProperty("http://schemas.microsoft.com/mapi/proptag/0x30070040") 'Get PR_CREATION_TIME
End If
pa.SetProperty "http://schemas.microsoft.com/mapi/proptag/0x30190102", pa.StringToBinary(retPolicy7Y) 'Set PR_POLICY_TAG
pa.SetProperty "http://schemas.microsoft.com/mapi/proptag/0x301A0003", retPeriod 'Set PR_RETENTION_PERIOD
pa.SetProperty "http://schemas.microsoft.com/mapi/proptag/0x301C0040", msgDate + retPeriod 'Set PR_RETENTION_DATE
sentItems(i).Save
End If
Next i
End Sub
查看使用OutlookSpy(单击 IMessage)或 MFCMAPI设置这些属性的现有邮件。可以使用 MailItem.PropertyAccessor.SetProperty 设置属性。
