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.
