The Exchange Server URL is used for connections for individuals or service accounts which need to connect Exchange services to Cirrus Insight. These products currently include Calendar Scheduling and Sync, but not the Sidebar sidebar. When needed, the Exchange URL should be configured by the Cirrus Insight admin and will apply for the entire company. When using Office 365, the server address is generally https://outlook.office365.com/ews/exchange.asmx. When using on premise Exchange, the exchange administrator must provide the server URL. Please refer your Exchange admin to this article for additional information. Cirrus Insight is not able to provide you with this information.
