REASON

This script error will appear when you use the function Date.now().

SOLUTION

In order to fix this, you have to change the way of setting the Date field that will work on both CRM Application and Outlook App as follows.

var today = new Date();
today.setDate(today.getDate());
formContext.getAttribute("kiwi_datereceptionappeloffre").setValue(today);

Bonus Tips:

• The function Date.now() does not work on the online version and you must use the new Date() approach
• The function Date.now() is still working on the on-premises version v9 but not on the App for Outlook if it is used

Hope This Helps!
