GetUserAvailabilityRequestType Class

The GetUserAvailabilityRequestType class represents an operation to get the availability information for a user.

System.Object
  ExchangeWebServices.BaseRequestType
    ExchangeWebServices.GetUserAvailabilityRequestType

Namespace:  ExchangeWebServices
Assembly:  EWS (in EWS.dll)
No code example is currently available or this language may not be supported.

The order in which mailboxes are added to the request represents the order in which mailbox information is received in the response.

The following code example shows you a GetUserAvailability query that includes the following elements:

  1. A time window for free/busy data that includes today and tomorrow.

  2. A request for detailed and merged free/busy information about the calendar events for each mailbox. This example shows a request for detailed information. However, the actual information that is returned can vary based on the caller's rights to view the calendar information for other mailboxes.

  3. A defined interval for which the merged free/busy data is to be returned; in this case, 30 minutes. This is ignored if merged free/busy data is not requested.

  4. A threshold definition that states that any suggested meeting time where 75% of the attendees are free is considered a Good meeting time.

  5. A window of suggested meeting times that includes today and tomorrow.

  6. A defined maximum number of nonworking hours as suggested meeting times per day; in this case, two.

  7. A maximum number of suggested meeting times per day; in this case, 10.

  8. A time span for suggested meeting times of 30 minutes.

  9. A minimum meeting quality time of Good.

  10. Four mailboxes to query for both free/busy information and suggested meeting times.

  11. A client application that has a locale in the Pacific Standard Time (PST) time zone and that observes daylight saving time.

The code example returns the free/busy information for each mailbox to the point that the caller has permission to view that data. It also returns a set of suggested meeting times that are organized by day and indicates the availability of the identified mailbox accounts.
