Then I would say "Outlook.com" instead of "the entirety of Outlook" because they are very different things.
I personally was not confused because I am aware that Outlook.com is a web based email service and Outlook is a piece of software.
He did say "outlook.com".
Are they different products?
Yes, very. outlook.com (formerly known as Hotmail) is an email provider. Outlook is an email client which can be used with any email provider.
I fucking hate MS branding, every fucking name confused into multiple services (remember Skype vs Skype for business ? That was different tech stack?) I thought he was talking about outlook.office365.com.
Also, outlook.com redirects to outlook.live.com/owa ....
