Service updates


This topic does not apply to Office 365 operated by 21Vianet. To learn about service updates, see Get technical, billing, and subscription support for Office 365 operated by 21Vianet.

To find out about features that have just released, or are about to be released, check out the Microsoft 365 Roadmap.


Updates and upgrades are rolled out to customers based on many factors, such as geography, language, data center, and subscription. This means that not all updates are available immediately to existing customers.

Targeted release

With Targeted release, your organization or a set of your users receive a select set of service updates approximately one week before we begin our standard release process. To learn more, see Microsoft release options.

Update notifications

Microsoft strives to notify customers in advance of any change that requires the administrator to take action to keep the service functioning normally. Unless otherwise noted, Microsoft will provide a minimum of 30 days advanced notification via Message Center when an update may require admin action.

Most service updates are bug fixes, performance improvements, and security updates that require zero action on behalf of the customer. New and improved features are found on the Microsoft 365 for business roadmap.

Please note that Microsoft follows the Online Lifecycle Policy.
