Calendar and contacts integrations are background processes that synchronize your Microsoft Exchange calendar and contacts with your Pega Sales Automation™. If the calendar or contact synchronization process fails, Pega Sales Automation sends an email notification message to the recipients that you specified when you configured the settings for your calendar or contact integration.
