Office 365 subscribers always have the latest version of Microsoft Office — currently Office 2016. They also get more frequent software updates than those who have purchased Office 2016 without a subscription, which means subscribers have access to the latest features, security patches and bug fixes. But it can be hard to keep track of the changes in each update and know when they’re available. We’re doing for you, so you don’t have to.

Following are key updates to Office 365 for Windows since Office 2016 was released in September 2015 — all the 2017 updates and the most important ones from 2016 and late 2015, with the latest releases shown first. We’ll add info about new updates as they’re rolled out.

Note: This story covers updates released to regular Office 365 for Windows subscribers. If you’re a member of Microsoft’s Office Insider preview program or want to get a sneak peek at upcoming features, see the company’s “What’s new for Office Insiders” page.

Also new in PowerPoint is that slides that have been modified by others are highlighted in a color, to make it easier to see at a glance which have been changed.

Other Office applications get a variety of minor additions, such as data connectors in Access now being able to import data from or link to data stored in Microsoft Dynamics or Salesforce. In Word, you can now create and edit equations using LaTeX syntax.

What IT needs to know: This update includes several security fixes for Outlook. Because of the security fixes, the update should be applied soon. Over the next few days, check for reports about problematic issues, and if all seems well, apply the update.

Version 1706 (Build 8229.2086)

Release date: July 13, 2017

The overall Office hole is a remote code execution vulnerability, which would also allow attackers to take control of the system if the current user is logged on with administrative user rights.

Version 1509 (Build 4229.1024)

Release date: September 22, 2015

This was the Office 2016 release. Here’s a summary of what was new:

  • Delve and Office 365 Planner were introduced for business versions of Office 365. Delve lets you see in-depth information about people with whom you work. Office 365 Planner makes it easier to plan and projects with others, using a central Planner Hub.
  • Outlook took on email overload with the introduction of a “Clutter” folder, where Outlook sends mail it determines to be non-essential. (It learns, over time, what is essential and what isn’t.) A Groups folder was introduced to business versions of Outlook, making it easier to track communications in the group, including conversation threads, meeting requests and videos.
  • TellMe was introduced, which makes it easier to find out how to accomplish tasks in Excel, Word and PowerPoint: Just type what you want to do in a “Tell me what you want to do” text box at the top of the screen.
  • Smart Lookup was introduced, which makes it easier to do research or fact-checking by doing a Bing search on a word or group of words. It’s available in Word, PowerPoint or Excel.
  • The Ribbon was given a solid color rather than white, with each Office application given its own identifying color.
  • Excel added six new charts, including Treemap, Sunburst, Waterfall, Histogram, Pareto and Box & Whisper.
  • Backstage (get there by clicking File on the Ribbon) shows you the email addresses of cloud-based services you've connected to your account, including SharePoint and OneDrive.

For a full review of Office 2016, see “Review: In Office 2016 for Windows, collaboration takes center stage.”

What IT needs to know:

  • Data loss protection (DLP) features were added to Word, PowerPoint and Excel. Previously, DLP was available only in communications-oriented tools, including Exchange, SharePoint, Outlook and OneDrive for Business.
  • System requirements for running Office 2016 were changed, including requiring 2MB of RAM.
  • Outlook received under-the-hood improvements, including some designed to improve Outlook's stability on unreliable networks and others designed to reduce the download time of email. Outlook’s speed of search was also improved.
  • An updated MAPI-HTTP protocol that Microsoft claims is more internet-friendly was released for Outlook.
  • Users were given the ability to reduce the amount of storage space Outlook uses by choosing to keep one, three, seven, 14 or 30 days of email on their devices.
  • A new service, Background Intelligence Transfer Service (BITS), was introduced; it prevents network congestion during Office updates.
  • Office was better integrated with System Center Configuration Manager (SCCM) so administrators can more efficiently distribute monthly updates as well as control the number and pace of feature updates and bug fixes.
