You need to be assigned permissions before you can run this cmdlet.

Parameter Required Type Description




The Anr parameter specifies a string on which to perform an ambiguous name resolution (ANR) search. You can specify a partial string and search for objects with an attribute that matches that string. The default attributes searched are:

  • CommonName (CN)

  • DisplayName

  • FirstName

  • LastName

  • Alias




The Filter parameter uses OPATH filter syntax to filter the results by the specified properties and values. The search criteria uses the syntax {<Property> -<Comparison operator> '<Value>'}.

  • <Property> is a filterable property.

  • -<Comparison Operator> is an OPATH comparison operator. For example -eq for equals and -like for string comparison. For more information about comparison operators, see about_Comparison_Operators.

  • <Value> is the property value. Values that aren't integers need to be enclosed in quotation marks ('Value').

You can chain multiple search criteria together using the logical operators -and and -or. For example, {<Criteria1>) -and <Criteria2>} or {(<Criteria1> -and <Criteria2>) -or <Criteria3>}.




The Identity parameter specifies the linked user that you want to view. You can use any value that uniquely identifies the linked user.

For example:

  • Name

  • Display name

  • Distinguished name (DN)

  • Canonical DN

  • GUID




This parameter is reserved for internal Microsoft use.




The ResultSize parameter specifies the maximum number of results to return. If you want to return all requests that match the query, use unlimited for the value of this parameter. The default value is 1000.




The SortBy parameter specifies the property to sort the results by. You can sort by only one property at a time. The results are sorted in ascending order.

If the default view doesn't include the property you're sorting by, you can append the command with | Format-Table -Auto <Property1>,<Property2>... to create a new view that contains all of the properties that you want to see. Wildcards (*) in the property names are supported.

You can sort by the following properties:

  • Name

  • DisplayName

  • City

  • FirstName

  • LastName

  • Office
