Everything to know about Microsoft Outlook, Microsoft's email and productivity platform that replaced MSN and Hotmail

• Microsoft Outlook is an email platform with productivity features like calendar and file-sharing.
• Microsoft discontinued its old email platforms, MSN and Hotmail, and folded them into Outlook.
• Outlook is free for personal accounts, but paid subscriptions offer greater storage and security.

In case you hadn't noticed, Microsoft has a released a lot of software over the past five decades. From its groundbreaking Windows operating system to its search engine Bing to stalwart programs like Word and Excel, now a part of the subscription-based Microsoft 365 suite, the company is a juggernaut of the software industry.

And when a company has released a plethora of programs, it's no surprise that the company has cancelled, merged, or rebranded many programs, too.

What is Microsoft Outlook?

Microsoft Outlook is, first and foremost, an email platform, but it goes well beyond just sending and receiving electronic mail. It also features a calendar, an easy way to store and manage contact information, file sharing of data saved in the cloud, and schedule and task tracking.

Microsoft Outlook is free to use for personal email and calendars, but there are some limitations. For example, a free Outlook account can only store up to 15 GB of mail, and that cap can be surprisingly easy to reach. Also, advanced security features are only available with a paid subscription.

Using Outlook is a great way to streamline your work and home life, keeping yourself up-to-date and aware of appointments, assignments, travel, deadlines, and more. You can set it up such that flight or hotel reservations are automatically added to your calendar, so that it will remind you of scheduled events, and you can set it to flag important messages for you — and to screen out the unimportant, too.

What happened to Hotmail and MSN?

Both Hotmail and MSN, also known as MSN Messenger, have been discontinued for a number of years, folded into other products. Chat messaging platform MSN was first released in 1999 and was rebranded as Windows Live Messenger in 2005.

Though it was used by hundreds of millions of people each month, following the acquisition of Skype in 2011, Microsoft found its own messaging platform redundant. The company shut the messenger service once known as MSN down for good in 2013. MSN email addresses still work, but they are managed via Outlook

Interestingly enough, the year 2013 also tolled the death knell for Hotmail. The mail platform was founded in 1996 and acquired by Microsoft the following year, and would enjoy nearly 17-year run until it was folded into Microsoft Outlook. You can still get an email address using @hotmail.com, but you'll need to sign up for it via Microsoft Outlook.

Is Microsoft discontinuing Outlook?

There are no plans for Microsoft to discontinue its Outlook platform. In fact, the company announced that as of the end of 2024, its Mail and Calendar applications would no longer be supported and that their functions would be rolled into Outlook, so Microsoft is putting even more of the proverbial eggs in the Outlook basket.

Outlook vs. Gmail

From contact management to calendar services to, of course, email, Microsoft Outlook and the Google Workspace, which includes Gmail, Google Meet, Google Drive, and Google Docs, have a lot of crossovers.

Google's professional suite is great for collaborative teams, offering more storage space and easy ways to connect, work on shared documents, and to swap files. Alternatively, people wanting advanced email features and numerous optional automations might prefer Outlook.

Both are superb workflow suites; it's truly a personal call.
