The Property property returns the name or tag of the property rendered in this column. Read-only.
objColumn.Property
Variant (Long or String)
The Property property is a long integer if the column property was specified by property tag. If it was specified by name, the Property property is a string. Predefined MAPI properties are always specified by property tag. Custom named properties can be specified either by tag or by name. The manner of specification depends on the setting of the varProperty parameter of the Columns collection's Add method. For example, if the column property being added is represented by a Field object, varProperty can be set to the field's ID property to specify by tag, or to the field's Name property to specify by name.
If the column property was specified by name, the property name in the string can optionally be prefixed with a GUID string identifying its property set. In this case, the GUID should be enclosed in braces. For more information and examples, see Using Named Properties.
