Microsoft has enabled a new feature in our Office 365 environment called Daily Briefings. These daily email messages are designed to help you remember meetings, to-do items, reply to correspondences.

According to Microsoft:

Briefing emails are personal and private and are only sent to you directly in your mailbox, which cannot be accessed by anybody else in your organization, including your IT admin or your manager. Briefing email data uses Exchange Online email and calendar data and processes and stores any insights or actions inside your Exchange Online mailbox, so data security is built in and enforced by Exchange.

Briefing emails do not include any new personally identifiable information about anybody else in your organization. Your Briefing emails are based on information that you already have access to but can’t quickly aggregate without help. For example, if you want to determine what commitments you made to others, you could manually review each email in your mailbox. The Briefing email helps you avoid this time-consuming process.

The Briefing email looks for actionable tasks in Outlook and includes the top results in the email. If these tasks are related to any upcoming meetings, they’ll be listed in context with the meeting. Meetings will also have links to any attached or potentially related documents.

The Adaptive version of the Briefing email also includes any last-minute options to schedule time to focus on deep work or to make progress on any of the tasks included in the email. Any existing focus time that’s already scheduled is also referenced in this section.
