Description

PushSubscriptionRequest

Represents a subscription to a push-based event notification subscription.

A text value that represents an integer is required if this element is used. The possible values for this element are 1 to 1440, inclusive. This element is optional. The default value is 30 minutes.

The StatusFrequency value is used by the server to retry a push notification when it does not receive a response to a push notification or status ping from the client. If the server does not receive a response, it retries sending the notification several times before it stops sending the notification. In EWS, the default retry interval is 30 seconds and subsequent retries are always double the time of the last retry interval. Retry times are not exact as they can be delayed due to other loads on the server. The following table shows how the retry intervals occur in the 30 minutes allotted by the default StatusFrequency value (assuming the server did not encounter any delays).

If the client does not receive notification messages from the server for a period of time that exceeds twice the time specified by StatusFrequency, the client should take an action such as recreating the subscription.
