Throttling in OneDrive

We have a registered AAD application marked as multi-tenant. We are using this App ID to generate a Token for Microsoft Graph.

  • The first user is a Global Admin in the Tenant where the app is registered.
  • The second user is part of another Tenant.

When the second user tried to use Microsoft Graph to get information from OneDrive, we sometimes get an HTTP 429 activityLimitReached error.

We read the guide about throttling and it says to repeat the request after the Retry-After value from the response header. But in our case there is no Retry-After field in the response.

We received this error by executing one request per day. Also, after receiving the 429, we can retry and get a successful result (after several attempts). This error appears only in the OneDrive, the other services are OK.

What can we do to avoid 429 error? How can we check the current limit or increase it?

GET https://graph.microsoft.com/v1.0/users/:userId/drives

What can we do to avoid 429 error? How can we check the current limit or increase it?

To avoid the 429 error, we must control our request, don't do too many request within limited time. The limit issue is known issue we canot increase it now.

Setting and publishing exact throttling limits sounds very straightforward, but in fact, it's not the best way to go. We continually monitor resource usage on SharePoint Online. Depending on usage, we fine-tune thresholds so users can consume the maximum number of resources without degrading the reliability and performance of SharePoint Online.

Above reference is from MS documentation about throttling and OneDrive for Business/SharePoint: https://docs.microsoft.com/en-us/sharepoint/dev/general-development/how-to-avoid-getting-throttled-or-blocked-in-sharepoint-online

I would suggest going to UserVoice for Graph and suggest an improvement (or upvote an existing one). The feedback helps Product Group prioritize future work based on the interest in those suggested improvements. But based on the above official docs, the best solution is still to contorl our request but not the feature request.

I do not have much experience with the onedrive-api but I have certainly experienced throttling when using the onenote-api.

This post on how onenote throttles may be more useful than the generic microsoft graph link in your question.
In particular, long calls against the api will result in throttling occurring much sooner than more targetted calls (and you need to let calls finish before issuing new calls, be very careful with queueing multiple curl requests).

Once you have been throttled trying the same call over and over will likely increase the length of time throttling occurs (I haven't seen as full day but I have seen several hours before).

I presume (but am not sure) that all microsoftgraph-api calls will internally count towards resource limits, but if you direct onedrive calls against the onedrive-api this will not count against the microsoft-graph limits and may allow the requests you need without throttling.
I would definitely recommend getting a second access token for the direct onedrive api (you can use the same refresh token) and try this approach.

If it is one user in particular that has issues maybe they have exceeded their tenant resources?
