用excel计算电子邮件VBA

Question

第一次发布 - 希望我已经清楚了。

我没有用excel VBA查看过，但已经设法通过这些论坛查找和更改（在我的IT区域的帮助下）一些代码，这些代码根据单元格中的日期统计Outlook文件夹中的电子邮件数量。在一个文件夹中计算电子邮件时，代码工作正常。我需要的代码是将多个文件夹中的电子邮件（其中的列表存储在工作簿的工作表中）计数并将计数输出到单独的列中。 （！希望能发布图片作为一个例子，但我需要更高的REP）

这里是我的代码至今：

Sub CountingEmails() 
' Set Variables 
Dim objOutlook As Object, objnSpace As Object, objFolder As Object 
Dim EmailCount As Integer, DateCount As Integer, iCount As Integer 
Dim myDate As Date 
Dim myCell As Object 

Dim dictEmailDates As New Scripting.Dictionary 

Dim folder1 As String, folder2 As String, folder3 As String 
folder1 = Sheets("Sheet1").Cells.Cells(2, 5) 
folder2 = Sheets("Sheet1").Cells.Cells(2, 6) 
folder3 = Sheets("Sheet1").Cells.Cells(2, 7) 

' Get Outlook Object 
Set objOutlook = CreateObject("Outlook.Application") 
Set objnSpace = objOutlook.GetNamespace("MAPI") 

' Get Folder Object 
On Error Resume Next 
Set objFolder = objnSpace.Folders(folder1) 

If Not IsEmpty(folder2) Then 
    Set objFolder = objFolder.Folders(folder2) 
End If 
If Not IsEmpty(folder3) Then 
    Set objFolder = objFolder.Folders(folder3) 
End If 

If Err.Number <> 0 Then 
    Err.Clear 
    MsgBox "Folder doesn't exist. Please ensure you have input the correct folder details." 
    Set objFolder = Nothing 
    Set objnSpace = Nothing 
    Set objOutlook = Nothing 
    Exit Sub 
End If 

EmailCount = objFolder.Items.Count 
FolderCount = objFolder.Folders.Count 

' Put ReceivedTimes in array 
CountEmails objFolder, dictEmailDates 

' Clear Outlook objects 
Set objFolder = Nothing 
Set objnSpace = Nothing 
Set objOutlook = Nothing 

' Count the emails dates equal to active cell 
Sheets("Sheet1").Range("A2").Select 
Do Until IsEmpty(ActiveCell) 

    DateCount = 0 
    myDate = ActiveCell.Value 

    If dictEmailDates.Exists(myDate) Then 
     DateCount = dictEmailDates(myDate) 
    End If 

    Selection.Offset(0, 1).Activate 
    ActiveCell.Value = DateCount 
    Selection.Offset(1, -1).Activate 
Loop 
MsgBox "Count Complete", vbInformation, "Count of Emails." 
End Sub 

Sub CountEmails(objFolder, dictEmailDates) 
EmailCount = objFolder.Items.Count 
FolderCount = objFolder.Folders.Count 

' Put ReceivedTimes in array 
EmailCount = objFolder.Items.Count 
For iCount = 1 To EmailCount 
    With objFolder.Items(iCount) 
     dateKey = DateSerial(Year(.ReceivedTime), Month(.ReceivedTime), Day(.ReceivedTime)) 
     If dictEmailDates.Exists(dateKey) Then 
      dictEmailDates(dateKey) = dictEmailDates(dateKey) + 1 
     Else 
      dictEmailDates.Add dateKey, 1 
     End If 
    End With 
Next iCount 

For iCount = 1 To FolderCount 
    CountEmails objFolder.Folders(iCount), dictEmailDates 
Next iCount 
End Sub 

希望有人能帮助？如果有什么额外的，或者我需要更多的解释，请让我知道！

干杯，阿德里安

如果我以下，这个问题是，folder1（或2或3）是被计数的唯一文件夹。这个问题似乎是，你只有一个文件夹加载到你的字典中（根据我认为它是folder3的代码）。我会通过重构代码来解决这个问题（我还添加了一些性能改进，并删除了一堆看起来什么都不做的东西）：

Sub CountingEmails() 
' Set Variables 
Dim objOutlook As Object, objnSpace As Object, objFolder As Object 
Dim myDate As Date 
Dim dictEmailDates As New Scripting.Dictionary 
Dim i As Integer 
Dim dcell As Range 'refering to range saves you having to keep retyping range to use, 
'reducing likelihood of typo 
Dim ws As Worksheet 
Set ws = ThisWorkbook.Worksheets("Sheet1") 'refering to ws saves having to type out 
'Sheet1 each time, and also makes it easier to update code if sheet name ever changes 

'Turn off screen updates for faster run 
Application.ScreenUpdating = False 

'Get the Outlook items setup 
Set objOutlook = CreateObject("Outlook.Application") 
Set objnSpace = objOutlook.GetNamespace("MAPI") 

'Start looping through the folders 
i = 0 
Do Until IsEmpty(ws.Cells.Cells(2, 5 + i)) 
    ' Get Folder Object 
    On Error Resume Next 
    Set objFolder = objnSpace.Folders(ws.Cells.Cells(2, 5 + i)) 

    'Get count of items and put in array based on ReceivedTimes 
    CountEmails objFolder, dictEmailDates 
Loop 

'Notice I completely removed Date and Folder count from this sub, they were only ever 
'set here, not used. Looked like legacy code from attempting to perform the count in 
'this sub rather than the self-referencing sub you created. 

' Clear Outlook objects 
Set objFolder = Nothing 
Set objnSpace = Nothing 
Set objOutlook = Nothing 

' Count the emails dates equal to current cell 
i = 2 
Set dcell = ws.Range("A" & i) 
Do Until IsEmpty(dcell) 

    DateCount = 0 
    myDate = dcell.Value 

    If dictEmailDates.Exists(myDate) Then 
     DateCount = dictEmailDates(myDate) 
    End If 

    dcell.Offset(0, 1).Value = DateCount 
    i = i + 1 
    Set dcell = ws.Range("A" & i) 
Loop 

Application.ScreenUpdating = True 
MsgBox "Count Complete", vbInformation, "Count of Emails." 
End Sub 

Sub CountEmails(objFolder, dictEmailDates) 
EmailCount = objFolder.Items.Count 
FolderCount = objFolder.Folders.Count 

' Put ReceivedTimes in array 
For iCount = 1 To EmailCount 
    With objFolder.Items(iCount) 
     dateKey = DateSerial(Year(.ReceivedTime), Month(.ReceivedTime), Day(.ReceivedTime)) 
     If dictEmailDates.Exists(dateKey) Then 
      dictEmailDates(dateKey) = dictEmailDates(dateKey) + 1 
     Else 
      dictEmailDates.Add dateKey, 1 
     End If 
    End With 
Next iCount 

For iCount = 1 To FolderCount 
    CountEmails objFolder.Folders(iCount), dictEmailDates 
Next iCount 
End Sub
