Used vs. limit

Record what is used—not just what is available.

The OneDrive usage report provides storage used and file counts per account. Keep deleted or inactive accounts separately labeled.

Historical coverage

Storage size does not equal record age.

Trend windows cover 7, 30, 90, or 180 days, while current file and storage totals describe retained state.

Troubleshooting
