Microsoft Word Rate Limits

Microsoft Word programmatic surfaces — the Word JavaScript API (Office.js Add-ins) executing in-app, and the Microsoft Graph Word / OneDrive endpoints — inherit Microsoft Graph's per-tenant / per-app throttling. Graph throttling is dynamic (based on resource consumption) rather than a single published per-second number; OneDrive enforces a documented per-user-per-app limit. 429 responses carry Retry-After.

Microsoft Word Rate Limits is the machine-readable rate-limit profile for Microsoft Word on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 4 rate-limit definitions, measuring varies.

The profile also includes 4 backoff/retry policies defined and response codes documented for throttled and serviceUnavailable.

Tagged areas include Rate Limiting, Productivity, Documents, and Microsoft.

Policies

Honor Retry-After
Microsoft Graph and OneDrive return 429 / 503 with Retry-After. Pause for that many seconds, then retry with exponential backoff and jitter.
Decorate user-agent
Use a meaningful User-Agent / x-anchorMailbox header per Graph guidance to reduce throttling impact.
Use ChangeNotifications, not polling
Subscribe to OneDrive change notifications instead of polling /drive/root/delta to avoid hitting per-minute caps.
Batch with $batch
Use Microsoft Graph $batch endpoints (up to 20 requests) to reduce per-call overhead.
