The class represents a search folder that is contained in a mailbox.
Assembly: EWS (in EWS.dll)
The class is used for both regular search folders and MicrosoftOfficeOutlook and Outlook Web Access visible search folders. For a search folder to be visible to Outlook and Outlook Web Access, the folder must be created under the SearchFolders distinguished folder.
If you use the calendar:Organizer property to create a search folder that has a restriction, a subsequent GetFolder call will return the restriction with the message:from property instead of the calendar:Organizer property. These two properties map to the same underlying MAPI property.
