Microsoft office not working after Sierra OS upgrade

Hi all,

Recently I upgraded the operating system of my Mac Book Pro to Sierra and since that time my Microsoft Office is not opening at all. I have tried to open word, powerpoint and excel and it gets stuck trying to open (sometimes it says updating fonts and gets stuck at 8%). I have left it for up to 30 mins but nothing. I tried uninstalling and reinstalling Office but the same problem occurred.

Any ideas why this may be happening and how to fix it?
