Microsoft Outlook.com to be replaced by Office 365

If you’ve gotten used to Outlook.com as an email client, hold on to your hat. It is going to be replaced by Office 365.
This year, Microsoft will start migrating all Outlook.com users to the Office 365 platform, according to an article on The Verge. This includes both the platform and the interface.
The reason behind the migration is to have Microsoft Outlook, Exchange (the server side of Microsoft email) and Office 365 platforms aligned. Because of this, the interface of Outlook.com will change in a few ways. Here’s an example of what it could look like:

 
Microsoft moved its webmail service from the Hotmail brand name to Outlook.com back in 2012. In the recent past, Outlook.com hasn’t seen many updates, while Gmail has been finetuning its interface and released a new email client called Inbox by Gmail last year. In terms of finetuning, Gmail recently dropped the Grid View in the Promotions tab,
Microsoft Outlook.com to be replaced by Office 365 is a big change, and changes to its web interface will mean users need to get used to it again, after the switch from Hotmail to Outlook.com.
It is expected that the interface of Outlook.com will also get some of the looks of Outlook Web App of Office 365, which already looks a bit like Outlook.com. The switch for the users will not be that big, in this case.
Time will tell how Outlook.com will look and work, and of course, how it will render emails, which is one of the main concerns for the email marketing industry and email designers.
