hebrew font not showing in outlook 2010 Calendar

Hi

I just imported the calendar csv file into Outlook 2010 running on Win 10 pro. I have done this in the past running on Win 7 and I select English and Hebrew in the calendar creation options, and the Hebrew displayed in Hebrew in the Calendar.

Now I am getting x's, etc... I have several Hebrew fonts installed, including "Alef" from this website....

Help? Suggestions? Fixes?
