What goes to the partner and what is communicated directly to customers? Partners own the billing relationship with the customer and are responsible for communicating to their customers on their subscription, transaction, and status. Microsoft sends direct communications to customers as it relates to operating the service, such as providing important service incident information or how to get the most out of the capabilities provided by the service. In-product communications/notifications, such as in Message Center and service health information, will continue to appear within the customer’s own Microsoft Office 365 admin center.
