Exchange Online App Access Policies are replaced by RBAC for Applications
Hi All,
A few Months ago i saw, that the recommendation for New-ApplicationAccessPolicy has changed.
App Access Policies are replaced by Role Based Access Control for Applications. To learn more, see Role Based Access Control for Exchange Applications. Don’t create new App Access Policies as these policies will eventually require migration to Role Based Access Control for Applications.
In Github you can see that the Change has been Published in August
