Using Outlook 2013 with Office 365, and cannot share any Contacts Group.
The menu options are there: "Copy/Paste, or Share, or Drag/Drop, Send As vCard, Send as Outlook Contact... but none of them work on the other end... can't get a Distribution List to save at all.
Copying/pasting and dragging/dropping from an email just saves the sender's Contact information, not the list itself.
And we can't share an entire Contacts folder. Have tried to create new Contacts folder, but can't get this Distribution List (Contact Group) into it either.
Have gone at this twice, and have yet to get the right way to manage a List in Outlook 2013 so as to share it.
