iCloud contacts sync with Outlook 2016 but don't appear when creating email
I'm running Outlook 2016, iCloud for Windows, and iCloud Outlook. My iCloud contacts appear when I click the people icon; so far so good. When I click "new email" and then click the "To" button, none of the iCloud contacts appear in the "Select Names: Contacts" dialog box. What do I need to do to get the iCloud contacts appearing in the dialog box?
