Newest Office Update 16.0.10730.20088 cause problems with Outlook CRM Adddin.
CRM Footer on messages, appointment etc and also CRM Fields became blank.
Resolution:
Outlook > File > Options
then in General Tab > Mark 'Optimize for compatibility'
Restart Outlook (twice : ) )
For me one restart was not enough, after next restart everything start to work properly.
Enjoy.
