UPDATED: Microsoft has extended the promo until June 30 2017.

Outlook.com Premium is now out of beta and is being offered at the super affordable price of $US19.95 until March 2017. If you need a custom domain, you can buy one directly from Microsoft for $US10 per year. After the promo, the price will rise to $US49.99

So what do you get?

• Custom domain for five users - You can create personalized email addresses (Outlook premium) for up to 5 people.
• Information sharing - Outlook Premium automatically configures information sharing between all of your user accounts (up to 5) for calendar, contacts and documents. Unlike other services, Microsoft Outlook Premium automatically configures the sharing so it is super simple. We don't know the shared space allocation yet (via OneDrive) but regardless, its a good deal.
• Ad-free inbox - You get a clean ad-free outlook.com experience. This means no graphical ads in outlook.com or onedrive.com.

This offer will expire March 31 2017 so jump on it now. Did I mention you will be renewed at lower rate in the future also? Get the offer here.

The same services on Google's GMAIL would cost $5 per user per month ($60 per year). If you activate all 5 users, it would cost you $300 on GMAIL ($19.99 on Outlook Premium).
