This script allows you to clear one or more locations where recipient information is cached, as this could influence end user experience with certain migration scenarios. You have the option to clear the AutoComplete stream (Name Cache) for Outlook and OWA, the Suggested Contacts or the Recipient Cache (Exchange 2013 only).
Script requires Microsoft Exchange Web Services (EWS) Managed API 1.2 or up, and Exchange 2010 or up or Exchange Online.
