Cannot send email to contact groups using current version of Live mail as downloaded from the Microsoft website on a new computer installed with Windows 10 and Outlook 2016

Contacts show up in contact list but send email is greyed out.

I can select the group from the to line in new email but am unable to send.  Error message indicates no recipients. 

Live mail works fine on another computer that was upgraded from Windows 7 and does not have Outlook installed.
