Microsoft 365, formerly Office 365, is a line of subscription services offered by Microsoft which adds to and includes the Microsoft Office product line. The brand was launched on July 10, 2017, for a superset of Office 365 with Windows 10 Enterprise licenses and other cloud-based security and device management products. On April 21, 2020, the consumer and small business plans of Office 365 were renamed Microsoft 365 to emphasize their current inclusion of products and services beyond the core Microsoft Office software family. Most products that were called Office 365 were renamed as Microsoft 365 on the same day. Microsoft 365 encompasses subscription plans that allow use of the Microsoft Office software suite over the life of the subscription, as well as cloud-based software-as-a-service products for business environments, such as hosted Exchange Server, Skype for Business Server, and SharePoint, among others.

## How to interpret this page

Estimated down reports are based on US Google Trends problem-intent searches. Values are relative activity from 0 to 100, not counts of submitted reports. The HTML chart averages samples into ten-minute intervals. Partial samples are excluded and missing samples are not invented.

Recorded outage reports and estimated activity are separate signals. Neither confirms that every user is affected. Missing or stale data does not establish that a service is working.
