最近经常发现发Email的时候忘记写邮件标题或遗漏附件，于是在网上搜索相关检查工具。有幸，找到了两个，一个是专门检查“空标题”的，另外一个是检查”遗漏附件“。可是发现无法在outlook 2003中将这两个VB script加进去，于是乎，想到一个办法：为何不能吧这两个检查合并为一个检查呢？

说干就干，先把这两个别人写的VB script抄下来参考（1）和（2），然后将其合并为（3），主要修改的是关于Cancel的赋值和判断，增加了两个布尔变量（cancel_Subject , cancel_Attach）来保存两个弹出窗口的判断值：

1）Blank Subject

Private Sub Application_ItemSend(ByVal Item As Object, Cancel As Boolean)
If TypeName(Item) <> "MailItem" Then Exit Sub

'CHECK FOR BLANK SUBJECT LINE
If Item.Subject = "" Then
Cancel = MsgBox("This message does not have a subject." & vbNewLine & _
"Do you wish to continue sending anyway?", _
vbYesNo + vbExclamation, "No Subject") = vbNo
End If
End Sub

2）Missing Attachment

' VBA program for Outlook, (c) Dan Evans. dan at danevans.co.uk
' Will check if your outgoing email mentions an attachment, but you've
' forgotten to attach it

' v1.03b of 29/7/05 - Modified by Leonard Slingerland (leonard at slingerland.biz) to have array of words rather than just one
' v1.03 of 10/8/04 - Modified to search through subject line as well as message body
' v1.02 of 16/10/02 - No change to code, but tested works with Outlook 2002 as well as Outlook 2000
' v1.01 of 23/9/01 - OK for "Attach" as well as "attach"
' v1.00 of 21/9/01 - Initial working version

Dim intRes As Integer
Dim strMsg As String
Dim strThismsg As String
Dim intOldmsgstart As Integer

' ADDED BY LS >>>
' - Does not search for "Attach", but for all strings in an array that is defined here
Dim sSearchStrings(3) As String
Dim bFoundSearchstring As Boolean
Dim i As Integer ' loop var for FOR-NEXT-loop
bFoundSearchstring = False

sSearchStrings(0) = "attach"
sSearchStrings(1) = "hereby"
sSearchStrings(2) = "bijlage" ' Dutch
sSearchStrings(3) = "hierbij" ' Dutch
' ADDED BY LS <<<

intOldmsgstart = InStr(Item.Body, "-----Original Message-----")
' intOldmsgstart is the location of where old/re/fwd msg starts. Will be 0 if new msg

If intOldmsgstart = 0 Then
strThismsg = Item.Body + " " + Item.Subject
Else
strThismsg = Left(Item.Body, intOldmsgstart) + " " + Item.Subject
End If
' The above if/then/else will set strThismsg to be the text of this message only,
' excluding old/fwd/re msg
' IE if the original included message is mentioning an attachment, ignore that
' Also includes the subject line at the end of the strThismsg string

' ADDED BY LS >>>
For i = LBound(sSearchStrings) To UBound(sSearchStrings)
If InStr(LCase(strThismsg), sSearchStrings(i)) > 0 Then
bFoundSearchstring = True
Exit For
End If
Next i
' ADDED BY LS <<<

If bFoundSearchstring Then
If Item.Attachments.Count = 0 Then
strMsg = "Dan Evans' Attachment Checker:" & Chr(13) & Chr(10) & "Your message mentions an attachment, but doesn't have one." & Chr(13) & Chr(10) & "Send the message anyway?"
intRes = MsgBox(strMsg, vbYesNo + vbDefaultButton2 + vbExclamation, "You forgot the attachment!")
If intRes = vbNo Then
' cancel send
Cancel = True
End If
End If
End If

3）Blank Subject & Missing Attachment

Private Sub Application_ItemSend(ByVal Item As Object, Cancel As Boolean)
If TypeName(Item) <> "MailItem" Then Exit Sub

Dim cancel_Subject As Boolean
Dim cancel_Attach As Boolean


'CHECK FOR BLANK SUBJECT LINE
If Item.Subject = "" Then
cancel_Subject = MsgBox("This message does not have a subject." & vbNewLine & _
"Do you wish to continue sending anyway?", _
vbYesNo + vbExclamation, "No Subject") = vbNo
End If

'CHECK FOR FORGETTING ATTACHMENT
Dim intRes As Integer
Dim strMsg As String
Dim strThismsg As String
Dim intOldmsgstart As Integer

' ADDED BY LS >>>
' - Does not search for "Attach", but for all strings in an array that is defined here
Dim sSearchStrings(1) As String
Dim bFoundSearchstring As Boolean
Dim i As Integer ' loop var for FOR-NEXT-loop
bFoundSearchstring = False

sSearchStrings(0) = "attach"
sSearchStrings(1) = "enclose"

' ADDED BY LS <<<

intOldmsgstart = InStr(Item.Body, "-----Original Message-----")
' intOldmsgstart is the location of where old/re/fwd msg starts. Will be 0 if new msg

If intOldmsgstart = 0 Then
strThismsg = Item.Body + " " + Item.Subject
Else
strThismsg = Left(Item.Body, intOldmsgstart) + " " + Item.Subject
End If
' The above if/then/else will set strThismsg to be the text of this message only,
' excluding old/fwd/re msg
' IE if the original included message is mentioning an attachment, ignore that
' Also includes the subject line at the end of the strThismsg string

' ADDED BY LS >>>
For i = LBound(sSearchStrings) To UBound(sSearchStrings)
If InStr(LCase(strThismsg), sSearchStrings(i)) > 0 Then
bFoundSearchstring = True
Exit For
End If
Next i
' ADDED BY LS <<<

If bFoundSearchstring Then
If Item.Attachments.Count = 0 Then
strMsg = "Attachment Checker:" & Chr(13) & Chr(10) & "Your message mentions an attachment, but doesn't have one." & Chr(13) & Chr(10) & "Send the message anyway?"
intRes = MsgBox(strMsg, vbYesNo + vbDefaultButton2 + vbExclamation, "You forgot the attachment!")
If intRes = vbNo Then
' cancel send
cancel_Attach = True
End If
End If
End If

If (cancel_Subject Or cancel_Attach) = True Then
Cancel = True
End If

End Sub

如何使用它呢，你可以选择（1）或（2）满足自己的需要，或者用（3）来使用两种检查功能。下面来简单介绍怎么用，或者说怎么嵌入到outlook 2003中：
a. 打开outlook
b. 按“Alt + F11” 键来打开VB Script
c. 点击左侧树状目录最下面的“ThisOutlookSession”，看到右边出现空白的编辑窗口
d. 把(1)或（2）或（3）的代码拷贝到编辑窗口，保存，退出VB Script编辑。（不用重启Outlook）

就这么简单，自己写个email测试一下功能看看？能否看到提示窗口？

经过测试，在Outlook 2002/2003上通过。

对于“Missing Attachment”功能，补充两句：这段代码是检查Email正文中的关键词：attach, enclose，来判断是否要求添加附件。根据自己需要，可以添加关键词，比如“附件”等等。代码中有：
Dim sSearchStrings(1) As String
和
sSearchStrings(0) = "attach"
sSearchStrings(1) = "enclose"
如果要增加关键词，就相应增加sSearchStrings(1)中的数字（如果有N个关键词，就为N-1），然后在下面添加相应的关键词，如：
sSearchStrings(2) = "附件"

好了，你也可以自己定制其它功能哦！欢迎讨论！
