Microsoft 365 backup gaps

Overview

The first snapshot (27 July 2026) outlines the four ways Microsoft 365 calendars can be shared and notes that the native Microsoft 365 Backup service protects Exchange Online, OneDrive and SharePoint but does not back up Teams chat content. It recommends third‑party backup providers for broader coverage, longer retention and immutable storage.

The second snapshot (29 July 2026) expands on the backup shortfalls, adding that Teams, Planner and Power Platform workloads are also excluded from automatic backup. It details the limited retention for Power Platform environments and the need for sandbox‑based restores. The note further highlights migration‑related data‑loss risks, such as undocumented mailboxes, missing SharePoint sites and synchronization gaps during hybrid moves, urging thorough planning and post‑migration validation.
