MemberCount Property

Microsoft Outlook Visual Basic

Returns a Long indicating the number of members in a distribution list. Read-only.

expression.MemberCount

expression    Required. An expression that returns a DistListItem object.

Remarks

The value returned represents all members of the distribution list, including member distribution lists. Each member distribution list is counted as a single member. That is, MemberCount is not an aggregate sum of the recipients in the distribution list plus recipients in member distribution lists. For example, if a distribution list contains 10 recipients plus one distribution list containing 15 recipients, MemberCount returns 11.

Example

This Microsoft Visual Basic/Visual Basic for Applications example steps through the default Contacts folder, and if it finds a distribution list with more than 20 members it displays the item.

Sub CheckDLs()
	Dim myOlApp As New Outlook.Application
	Dim myOlFolder As Outlook.MAPIFolder
	Dim myOlItems As Outlook.Items
	Dim myOlDistList As Outlook.DistListItem
	Dim x as Integer
	Set myOlFolder = myOlApp.GetNamespace("MAPI").GetDefaultFolder(olFolderContacts)
	Set myOlItems = myOlFolder.Items
	For x = 1 To myOlItems.Count
		If TypeName(myOlItems.Item(x)) = "DistListItem" Then
			Set myOlDistList = myOlItems.Item(x)
			If myOlDistList.MemberCount > 20 Then
				MsgBox myOlDistList.DLName & " has more than 20 members."
				myOlDistList.Display
			End If
		End If
	Next x
End Sub
		

If you use VBScript, you do not create the Application object, and you cannot use named constants. This example shows how to perform the same task using VBScript.

Set myOlFolder = _
    Application.GetNamespace("MAPI").GetDefaultFolder(10)
Set myOlItems = myOlFolder.Items
For x = 1 To myOlItems.Count
    If TypeName(myOlItems.Item(x)) = "DistListItem" Then
        Set myOlDistList = myOlItems.Item(x)
        If myOlDistList.MemberCount > 20 Then
            MsgBox myOlDistList.DLName & _
                " has more than 20 members."
            myOlDistList.Display
        End If
    End If
Next
