You will have recently started receiving the Cortana daily briefing emails.
The Briefing email helps you stay in control of your calendar and be intentional about your day. Within two hours of your workday (as set up in Outlook), you'll get an email about any relevant items to help you better prepare for the day ahead, including:
- Outstanding commitments, requests, and follow-ups to and from other collaborators in email that might have fallen through the cracks.
- Documents related to today’s meetings that you might want to review beforehand.
- Suggested focus time you can schedule to help get independent work done.
If you don't want to receive these, you can unsubscribe by following the link in the email you received.
If you want to know more about it, then follow this link for a little more information on the daily briefing emails.
