What Version of Microsoft Office Do I Have?

If you’ve ever needed tech support, installed a new add-on, or opened a file that wouldn’t cooperate, you’ve probably asked yourself: What version of Microsoft Office am I using?

It’s a common question—and knowing the answer can save you time and headaches. Here’s how to find out quickly and accurately.

Why It Matters

Different versions of Microsoft Office have different features, file compatibility, and update policies. Whether you’re using Office 2016, Office 2019, Office 2021, or a Microsoft 365 subscription, it affects what your software can (and can’t) do.

How to Check Your Microsoft Office Version

The exact steps vary slightly depending on which app you’re using—Word, Excel, Outlook, etc.—but the general process is the same.

For Windows Users:

1. Open any Office application (like Word or Excel).
2. Click “File” in the top-left corner.
3. Select “Account” or “Office Account” from the sidebar.
4. Look under the “Product Information” section.
   • You’ll see something like “Microsoft 365”, “Office 2019”, or “Office 2016”.
5. For more detail, click “About Word” (or Excel, etc.).
   • A window will pop up with the full version number and build info.

For Mac Users:

1. Open any Office app.
2. Click the app name in the top menu bar (e.g., “Word” or “Excel”).
3. Select “About [App Name]”.
   • You’ll see the full version and license type (like Office 365 or Office 2019).

Office Version vs. Office Build

The version tells you what product you’re using (e.g., Office 2019), while the build number refers to the specific update version. Microsoft 365 apps, for example, update regularly and show a much longer build string like 16.0.12345.20200.

If you’re troubleshooting an issue, both can be important. Tech support might ask for them specifically.

Can I Still Use Older Versions?

Yes, but with limits. Microsoft has ended support for Office 2013 and older, meaning no security updates or bug fixes. Office 2016 and 2019 are still functional but lack many cloud-based features of Microsoft 365.

TL;DR

• Open Word, Excel, or another Office app.
• Go to File > Account (Windows) or About [App Name] (Mac).
• Check the version info under Product Information.
• Knowing your version helps with compatibility, updates, and support.
