"Synchronize message" with a Large folder with Outlook REST API

Question

I am using the beta endpoint Office365 Outlook REST API to synchronize a large Office365 Outlook folder, see doc here.

The response is paginated... and after many calls to the first synchronization of this big folder, I received this error:

{"error":{"code":"LocalTime","message":"This operation exceeds the throttling budget for policy part 'LocalTime', policy value '0',  Budget type: 'Ews'.  Suggested backoff time 299499 ms."}}

Looks like I have requested too much the API. What is the best way to handle it? Should I implement some kind of retry policy?

Answer 1

Yes, this is our current throttling mechanism, which is a temporary measure while our "real" throttling implementation is being deployed. To handle this, you'll need to do a retry after about 5 minutes.
