The Microsoft Office 365 Outlook.com Cert Pinned App in Steering configuration…

What is the default (new/recently created tenants) for Custom App Domains?

What is the value in your tenant for Custom App Domains?

Curious if it is best practice and/or common to have this set to *, empty, or specific values.

This question comes as the OOB Microsoft Office 365 Outlook.com contains the process below, that is used throughout additional Microsoft products (such as Teams and the Microsoft 365 Copilot app). If your Custom App Domains is set to * for the  Microsoft Office 365 Outlook.com Cert Pinned App in Steering configuration, then all traffic (regardless of the Microsoft app) will bypass Netskope inspection (including DLP policies).
