OneDrive for Business is each employee's personal work cloud: drafts, notebooks, and files they own in Microsoft 365. It is not a substitute for team libraries, that is SharePoint, but it is where much daily work starts.
OneDrive vs your old "My Documents"
| Aspect | OneDrive for Business |
|---|---|
| Ownership | Tied to the user account |
| Sharing | Links with permission levels you control |
| Sync | Optional desktop sync via OneDrive client |
| Admin | IT can set sharing defaults and retention |
Files here follow HR offboarding processes, when someone leaves, their manager should claim important content before the account is disabled.
Good uses
- Works-in-progress before publishing to a team site
- Personal meeting notes and scratch spreadsheets
- Known Folder Move redirecting Desktop/Documents to cloud backup
Poor uses
- The only copy of company-critical data with no backup owner
- Company-wide policy manuals everyone needs after the author leaves
- Large video archives better suited to SharePoint streaming policies
Sharing discipline
Default to specific people links inside the organization. Anyone links should be rare and monitored, many firms disable them tenant-wide.
Storage and versioning
Plans include per-user quotas (often 1 TB on business tiers). Version history helps recover from accidental overwrites; it is not a full backup product for ransomware, pair with Defender and admin alerts.
