Nivedipa-MSFT​ Thanks for confirming the polling approach using the delta API.

Could you also share if there are any defined or recommended rate limits for /messages/delta and /replies APIs? Since we may need to poll across a large number of channels, any guidance on safe polling intervals or throughput (per app/tenant) would be really helpful to avoid throttling.
Thanks!

Hello Yash-ClearFeed,

Teams message APIs (/messages/delta, /replies) share a limit of 60 requests/min per app per tenant.

  • Under 60 channels: Polling every 60s is feasible
  • 60+ channels: Use Graph change notifications (webhooks) as the primary method, with delta queries as periodic catch-up
  • Always handle HTTP 429 with Retry-After and exponential backoff
