I have a excel file like that;

 displayname             legacyexchangedn
 Joe Black        /o=OU/ou=Exchange Administrative Group(FY3BO5312PDLT )/cn=Recipients/cn=joeblack233445 

I want to use this excel records and adding exchange users x500 email address as legacyexchange dn. When i run the powershell script it will find user Joe Black with displayname and add legacyexchangedn value as x500 secondar mail address. Thanks
