OneDrive vs. SharePoint

OneDrive and SharePoint are both Microsoft 365 storage, but they answer different ownership questions. OneDrive is an individual's personal work storage; SharePoint is shared, team- or organization-owned storage. (The Google equivalents are My Drive for the individual and Shared Drives for the team.)

The distinction that matters: is a given file owned by a person or by the organization? Even personal work storage sits under the corporate umbrella, but a file in someone's OneDrive is structured around that individual — which becomes a problem when they leave and they were the only one who could manage it.

The guidance is to keep as much as possible in the shared context — SharePoint or Shared Drives — because turnover is inevitable and you don't want critical data trapped behind a departed employee's personal ownership. Put team data where the team, not an individual, owns it.
