We have a CSV list of Lync SIP logins (ex. email@example.com), but need to match this list with their Active Directory usernames and/or employeeID. GET-CSuser will not return the necessary AD variable. Anyone have any ideas? Thanks.
Sorry for the confusion...What we need from the list of sip addresses is to query AD for the actual AD usernames (specifically employeeid attribute) of the user. Some of the users do not have an email address (most do) that would match their sip address.
