I just called your support line.
They told me I cannot use Office365 because it is not installed on the computer and needs internet access all the time to run.
As a test, I disabled my internet connection and I ran Excel with not problem. I cannot access my files on OneDrive, but I can access files on my computer.
So, the question remains: Why is it not possible to use it with NewViews?
In the near future, many NewViews users will be using Office365.
