Thank you for your reply @Juan Carlos González Martín 


From a functionality point of view, we're ready to accept that features might change, or even drop.

The document that is causing some questions at our end is 


"The Whiteboard apps for Windows 10 and iOS meet Tier C, which means that they conform to global standards including SOC 1, SOC 2, ISO 27001, HIPAA, and EU Model Clauses. When the Whiteboard Web App (currently in Preview) is made generally available, it will meet the same level of compliance standards"




Can we trust preview apps to comply with the basic security assurances that we get from other parts of M365? If we save a whiteboard with commercially sensitive IP, is it secured with the same level of assurance that we get from other O365 services?

Anything I can share with our security team to help alleviate concerns about preview features in general, or with the whiteboard preview in particular would be greatly appreciated
