Application Impersonation RBAC Retirement

 The Application Impersonation role in Exchange Online will be deprecated in 📅 February 2025. 

➡️ Take immediate action to transition applications to alternatives to avoid disruptions:

⭐ Transition to Microsoft Graph: Migrate to Microsoft Graph as EWS is being phased out.

⭐ Implement App-only Authentication: Update EWS applications to use App-only access (EWS.AccessAsApp OAuth Application permission) and RBAC for Applications.
