  LPSPropValue pprop


[in] Pointer to an IMAPIProp interface on which the property value is to be set or changed.


[in] Pointer to the SPropValue structure defining the value to be set on the pmp property.

Unlike the IMAPIProp::SetProps method, the HrSetOneProp function never returns any warnings. Because it sets only one property, it simply either succeeds or fails. For setting or changing multiple properties, SetProps is faster.

You can retrieve a single property with the HrGetOneProp function.
