Important: Rules to follow when deleting from aduser:

• If AdUser has 2 different CustomerId, keep the record which has highest value for ADUserId.
• If CustomerId is same, check for ADUserid in Mailbox table, keep record which is in mailbox table.
  • If no enterprise service enable on ADUser, keep latest record.
