MAPI common

This property can also specify the categorization level of a row in a contents table or the hierarchy depth in a hierarchy table. The depth is zero-based, where zero represents the leftmost category. In all cases, the property value represents a relative value rather than an absolute value. In the hierarchy table, for example, the depth value is relative to the container from which the hierarchy table was retrieved. The depth does not represent an absolute depth from the root container.
