What version of Outlook do I have?

With so many Outlook apps and services, it can be confusing to know which version you're using. To find out, choose how you access Outlook:

Outlook is a powerful application for managing your email, contacts, and calendar. Follow these steps to find out which version of Outlook is installed on your computer.

  1. In Outlook, choose File.

    This is what the ribbon looks like in Outlook 2016.

  2. Select Office Account.

    If you don't see Office Account, option, choose Help. You'll see the product version on the right side of the page.

  3. You'll find your version and build number under Product Information. For example, the following displays for Microsoft Office 365 ProPlus, which includes Outlook.

    Version and build number under Product Information

  4. If you need to know whether you're using the 32-bit version or the 64-bit version of Outlook, select About Outlook.

    Choose the About Outlook box.

  5. The top of the About Outlook box shows the version number and 32-bit or 64-bit distinction.

    At the top of the box it says 32 or 64 bit.

Some Outlook features are only available as part of Outlook for Office 365 or the Office Insider program.

Select File > Office Account. If you see Office 365 or Office Insider, you're running Outlook for Office 365 Monthly Channel or an Insider build.

See File > Office Account to find your Outlook version.

If you’re using Windows 10, and your Outlook doesn’t match the images here, there are two possible reasons.

  1. You’re using an older, unsupported version of Outlook, such as Outlook 2003. You can often find the Outlook product version by selecting Help > About.

  2. You’re using Windows 10 Mail. Windows 10 Mail is a free program included with all Windows 10 computers. If you’re using Windows 10 Mail, your Inbox will look something like this.
