Manage your maintenance window

Microsoft regularly performs updates and maintenance on customer engagement apps (Dynamics 365 Sales, Dynamics 365 Customer Service, Dynamics 365 Field Service, Dynamics 365 Marketing, and Dynamics 365 Project Service Automation) to ensure security, performance, availability, and to provide new features and functionality. This update process delivers security and minor service improvements on a weekly basis, with each update rolling out region-by-region according to a safe deployment schedule, arranged in Stations. For information about your default maintenance window for environments, see Policies and Communications for service incidents.
