What version of Outlook do I have?

With so many Outlook apps and services you can use to access your email messages, appointments, and contacts, 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. To find out which version of Outlook is installed on your computer, do the following:

  1. In Outlook, click File.

  2. Click Office Account.

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

  3. You'll find the version and build number under Product Information. For example, the following picture shows I have Microsoft Office 365 ProPlus installed. Outlook is part of that suite.

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

    Choose the About Outlook box.

  5. The top of the About Outlook box shows the version number and whether you're using 32-bit or 64-bit.

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

If you’re using Windows 10, and your Outlook doesn’t match the images shown, 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.
