The WeightedRank element<2> specifies the rank of this contact entry in the recipient information cache. It is defined as an element in the Contacts namespace.
The value of this element is an integer data type, as specified in [MS-ASDTYPE] section 2.5.
Clients can use the WeightedRank element to determine which entries in a recipient information cache list are displayed first in an auto-completion field. Higher values of the WeightedRank element identify the most relevant entries.
The WeightedRank element is only returned in a recipient information cache response. For more details about the interaction with the recipient information cache, see [MS-ASCMD] section 126.96.36.199.3.
