This enumeration has a FlagsAttribute attribute that allows a bitwise combination of its member values.

Namespace:  ExchangeWebServices
Assembly:  EWS (in EWS.dll)

public enum FreeBusyViewType

Member nameDescription
NoneThis value is not valid for requests. This value is valid for responses.
MergedOnlyRepresents an aggregated free/busy stream. In cross-forest scenarios in which the target user in one forest does not have an Availability service configured, the Availability service of the requestor retrieves the target user’s free/busy information from the free/busy public folder. Because public folders only store free/busy information in merged form, MergedOnly is the only available information.
FreeBusyRepresents the legacy status information (free, busy, tentative, and OOF). This also includes the start times and the end times of the appointments. This view is richer than the legacy free/busy view because individual meeting start and end times are provided instead of an aggregated free/busy stream.
FreeBusyMergedRepresents all the properties in FreeBusy with a stream of merged free/busy availability information.
DetailedRepresents the following:
  • The legacy status information (free, busy, tentative, and OOF)

  • The start times and the end times of the appointments

  • Various properties of the appointment such as subject, location, and importance

This requested view will return the maximum amount of information that the requesting user has permission to access. If merged free/busy information only is available, as when you are requesting information for users in a Microsoft Exchange Server 2003 forest, MergedOnly will be returned. Otherwise, FreeBusy or Detailed will be returned.

DetailedMergedRepresents all the properties in Detailed with a stream of merged free/busy availability information. If merged free/busy information only is available, for example if the mailbox exists on a computer that is running Exchange 2003, MergedOnly will be returned. Otherwise, FreeBusyMerged or DetailedMerged will be returned.

This enumeration is used by the RequestedView property of the FreeBusyViewOptionsType object in the request to indicate the type of free/busy information to return in the response. This enumeration is also used by the FreeBusyViewType property of the FreeBusyView object to indicate the type of free/busy information that is returned in the response.

The following table lists the properties for the different view types and the corresponding MAPI property. Each view type builds upon the former view type.
