Outlook.com is a personal information manager web app from Microsoft consisting of webmail, calendaring, contacts, and tasks services. Founded in 1996 by Sabeer Bhatia and Jack Smith as Hotmail, it was acquired by Microsoft in 1997 for an estimated $400 million and relaunched as MSN Hotmail, later rebranded to Windows Live Hotmail as part of the Windows Live suite of products. Microsoft phased out Hotmail in October 2011, relaunching the service as Outlook.com in 2012.

## 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.
