Microsoft has finally bitten the bullet and acknowledged the catch-up ball it needs to play in the e-mail space.

Last week, Microsoft announced that it’s unveiling a completely revamped version of its Hotmail free online e-mail service.

Dubbed “Outlook” in a bid to transfer some of the goodwill from Microsoft’s popular Office email application to the free e-mail space, the successor product to Hotmail incorporates functionalities designed to make it more directly competitive with Google Gmail, which has been growing by leaps and bounds in recent times.

You may not realize it from the persistent dearth of industry press coverage about Hotmail, but it’s actually held the rank of the world’s largest online mail service, owning more than a third of the world market share (~325 million users), according to June 2012 reporting from cyber-statistics firm comScore.

But Microsoft’s margin over rivals has shrunk considerably, with Gmail hard on its tail at ~31% market share of users and Yahoo holding a similar percentage (~32%).

It may be surprising to learn that in the ever-changing digital space … but prior to this revamp Microsoft hadn’t updated any of the features or functionality of Hotmail in nearly a decade.

“A lot has changed in the last eight years, and we think it’s time for a fresh look at e-mail,” Chris Jones, a Microsoft exec, stated in a blog post that has to be the understatement of the decade.

Here’s some of what’s in store for users when they switch from Hotmail to Outlook:

• A clean, uncluttered look – just like Gmail.

• Tasteful, unobtrusive advertisements appearing in the right column of the screen – just like Gmail.

• Users can link up with all major social media accounts to view the latest updates from their contacts and friends – just like Gmail.

Is this beginning to sound a bit repetitive?

But there is one feature that may give Outlook a bit of a leg up on its free online competitors: The service will automatically detect mass messages like sales notices, daily deals, newsletters and social updates and place them in separate folders. Users can customize this functionality to sort incoming e-mail any way they wish.

I haven’t used Hotmail in the past … although I might be tempted to consider Outlook now that these newest innovations have been added.

But the long-term success of Outlook – and any free e-mail platform – is going to be how effectively they can connect various online assets together to provide “one-stop convenience” for users.

One thing’s certain: There’s no way Microsoft can let another eight years go by before making more enhancements to its free e-mail service offering, considering the always-aggressive posture of Google and its Olympian competitive spirit.
