DistListItem.MemberCount Property (Outlook)

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

expression .MemberCount

expression A variable that represents a DistListItem object.

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.

This Microsoft 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.

 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." 
 End If
