Microsoft 365 - What version of Microsoft Office/Outlook am I using?

This document describes how you can determine the version of Office you have installed on your computer. These instructions assume you already have an Outlook profile/account configured. If you do not have Outlook configured, you can substitute Outlook with any of the other Office applications in the steps below.

Important:

  • To get the latest features/updates, it is recommended that you install the Microsoft Office 365 ProPlus/Subscription/enterprise version of Office/Outlook. The Professional Plus/2016/2019/Volume License version is only receiving security updates.
  • Preview and Beta Software in M365 - The Preview channel for Microsoft 365 apps and any pre-release clients are considered use at your own risk. At this time UW-Madison Microsoft 365 Service Team is unable to offer support for unreleased versions of client software. If you wish to use pre-release software and contact the DoIT Help Desk for support, you will be asked to reinstall the current version of the software before any troubleshooting and assistance can be provided. Please contact Microsoft directly by using the feedback feature inside of the client if you wish to provide feedback directly.
