Microsoft 365 native experiences
When you enable Microsoft 365 storage in a vault, M-Files saves all document files in SharePoint Embedded (SPE) containers. M-Files continues to manage metadata and object structure. This lets you use Microsoft features natively with M-Files-managed content. Microsoft 365 storage is enabled separately for each vault as part of a phased rollout.
