Authentication bypass
Use the Authentication Bypass tab of the page to select cloud applications. Requests to selected applications will bypass the authentication process configured in Content Gateway manager. See Content Gateway user authentication for more information.
Check the box next to Office 365 and related applications to bypass authentication for all requests to any Office 365 product.
Important:
Authentication bypass for Office 365 is supported with explicit proxy deployments.
Transparent proxy deployments are supported only if Content Gateway bypass for Office 365 and SSL decryption bypass for "Office - Collaboration" categories are not enabled.
