 ### -ConfiguredAttributes
 The ConfiguredAttributes parameter specifies the recipient MAPI properties that are available in the OAB. This parameter uses the syntax: "\<Name1\>,\<Type1\>","\<Name2\>,\<Type2\>"... where \<Name\> is the name of the MAPI property (for example, MobileTelephoneNumber), and \<Type\> is the value ANR (ambiguous name resolution), Value, or Indicator.
 
-To enter multiple values and overwrite any existing entries, use the following syntax: \<value1\>,\<value2\>,...\<valueN\>. If the values contain spaces or otherwise require quotation marks, you need to use the following syntax: "\<value1\>","\<value2\>",..."\<valueN\>".
-
-To add or remove one or more values without affecting any existing entries, use the following syntax: @{Add="\<value1\>","\<value2\>"...; Remove="\<value1\>","\<value2\>"...}.
-
 To reset this parameter back to the default values, use the UseDefaultAttributes switch.
