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

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.
