2.What is Storage Optimizer?
The purpose of the Storage Optimizer application is to help identify the areas where storage usage could be optimized by archiving unused documents and cleaning up the document versions.
The application is implemented as a desktop application using .NET8. By default, .NET 8 and WebView2 are supposed to be installed on the client’s machines. If they are missing or if an update is required, the installation package will download and install both components in the background before installing the application.
The application requires Microsoft 365 account credentials to connect to Microsoft 365. During this process, it will register an application in the Entra ID (formerly called Azure Active Directory) with the necessary permissions. This account must have permission to enroll applications in the Entra ID.
