Returns an Integer (int in C#) value indicating the number of members in a distribution list. Read-only.
Assembly: Microsoft.Office.Interop.Outlook (in Microsoft.Office.Interop.Outlook.dll)
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.
