Microsoft Outlook
Introduced: 1997
Also known as: Microsoft Office Outlook (2003 and 2007 releases)
Email client and personal information manager. Superseded Microsoft Schedule+ calendar program and Microsoft Exchange Client email program.
Outlook Express
Introduced: 1996
Discontinued: 2001
Also known as: Microsoft Internet Mail and News (1996-97)
Email and USENET client bundled with Internet Explorer. Despite the name, it was not a stripped-down version of Microsoft Office's Outlook, but rather a completely unrelated program.
Outlook Web App
Introduced: 1995
Also known as: Exchange Web Connect (1995-97), Outlook Web Access (1997-2010)
Webmail service bundled with Microsoft Exchange Server. Most easily recognized as the webmail service used by Microsoft's Office 365 for Education package that every college in the world seems to be using these days.
Outlook.com
Introduced: 1996 (as Hotmail), 2012 (as Outlook.com)
Also known as: Hotmail (1996-2013)
Rebranding of the long-established Hotmail webmail service. The two brands were briefly used side-by-side, though as of last year the Hotmail brand seems to have been retired. (Obviously, old
@hotmail.com addresses can be kept.)

Not to mention the mess that is MSN Search Windows Live Bing's branding history
Also, apparently OneDrive is seven years old, which is news to me. I only remember it becoming a distinct thing after it dropped the Windows Live name in 2010-11ish.
I assumed it was because Outlook was O, but they didn't have a problem using P for both PowerPoint and Publisher
we'll all be one
think of me, when you see the sun or feel the wind~ o/`
