Subscription Grouping limits RRS feed

  • Question

  • With Exchange EWS Streaming Subscriptions we group subscriptions using the X-PreserveServerAffinity header.  The documentation says that the maximum number of SubscriptionId values permitted in a request is 200, so we should limit group size to 200.

    Has this changed recently as I seem to be able to groups of several thousand users?
