Issue/Introduction

Chrome browser users are unable to edit SharePoint documents in Excel.  The document opens, but when the user clicks the button to edit the document in Excel, the expected pop up never appears.  This is not affecting IE users, and is only affecting external users who go through an external reverse proxy.

Environment

Release: MSPSSO99000-12.8-Single Sign-On-for Business Users-MSP
Component:

Cause

The following header, set in the OWA SharePoint farm, was causing the problem:

Content-Security-Policy: default-src https: data: 'unsafe-inline' 'unsafe-eval' 

Resolution

Setting the value of this header to blank (no value) resolved the problem.
