Parameter Name



To identify the type of calendar user specified by the property.

Format Definition

This property parameter is defined by the following notation:

 cutypeparam        = "CUTYPE" "="
                    ("INDIVIDUAL"   ; An individual
                   / "GROUP"        ; A group of individuals
                   / "RESOURCE"     ; A physical resource
                   / "ROOM"         ; A room resource
                   / "UNKNOWN"      ; Otherwise not known
                   / x-name         ; Experimental type
                   / iana-token)    ; Other IANA-registered
                                    ; type
 ; Default is INDIVIDUAL


This parameter can be specified on properties with a CAL-ADDRESS value type. The parameter identifies the type of calendar user specified by the property. If not specified on a property that allows this parameter, the default is INDIVIDUAL. Applications MUST treat x-name and iana-token values they don't recognize the same way as they would the UNKNOWN value.
