Bing isn't the service that Microsoft announced would receive a healthy dose of AI today. At an event focused on AI today, Microsoft also took the wraps off of a number of AI enhancements it is bringing to Office 365 and Cortana.

For Office 365 users, Microsoft is launching a preview of Insights in Excel, which can automatically seek out and highlight patterns that it detects. Insights uses machine learning to help "identify trends, outliers, and other useful visualizations," Microsoft says.

Another AI feature hitting Office 365 is a new tool called Acronyms in Microsoft Word. Leaning on machine learning, Acronyms will help people understand shorthand used in their workplace by searching for definitions and terms found in emails and documents. Acronyms will start rolling out to Word Online for Office 365 commercial Insiders in 2018. Meanwhile, Tap, another feature in the works for Word, will let Office 365 users quickly search for relevant documents, spreadsheets, and presentations within your organization without leaving what you're working on.

Outlook on mobile is also getting some love, integrating with Cortana to help surface notifications for when it's time to leave for an appointment. Outlook will helpfully surface driving and transit directions, along with an ETA based on your current location.
