Hello. Looking for help with constructing a powershell script that will do the following
1. csv file contains list of users (upn)
2. PowerShell script reads all users from csv file (step1.) does a compare or hash table against users in three specific OU's in AD using (upn). The three specific OU's contain all of our vendor accounts
3. If a match is found, extend account expiration + 90 days
4. if a match is not found write the non matched accounts to a separate .csv file
Thank you very much in advance for any help
