With so many Outlook apps and services, it can be confusing to know which version you're using.

To find out which version of Outlook you're using, select a tab below.

There are now two versions of Outlook for Windows: new Outlook for Windows and classic Outlook for Windows.

To find out whether your Outlook for Windows is the new or classic version, look for the Settings   Settings in the top right corner. If you have the Settings button, you have the new Outlook. If the Settings button is missing, you're using classic Outlook.

My Outlook doesn't look like this, but I'm using a Windows 10 or Windows 11 PC

If you're using Windows 10 or Windows 11, and your Outlook doesn't match the images here, there are two possible reasons.

  1. You're using an older, unsupported version of Outlook, you can often find the Outlook product version by selecting Help > About.

  2. You're using Windows 10 or Windows 11 Mail. Windows 10 or Windows 11 Mail is a free program included with all Windows 10 or older Windows 11 computers. If you're using Windows 10 Mail, your Inbox will look something like this.
