I am planning an upgrade to the latest version from 17 and need to know if the basic feature was added so a user can create a contact group and send email to that group?  I know SM has contact categories, but no way to send an email to a category in the past, has this changed?

Now that MAPI is here I would like to confirm users can create contact groups in outlook and they sync to the server?  When I migrate users to smartermail they typically have many contact groups in outlook which never synced befor so I wanted to see if this will work now?
