Microsoft may be planning to add the “Inbox Tabs” feature to the Outlook web. Leaked images posted on Twitter reveal that soon users will be able to use a tabbed UI with “Focused inbox”, social, promotions and newsletter as options.

In fact, one can toggle on and off these tab options for the tabbed UI and accordingly number of tabs can be managed.

Focused inbox will have the most important mails, the social tab will feature all social networking mails, promotions will have mails related to deals and offers and finally, the newsletter will feature mails from the subscribed mailing lists.

While this looks like an interesting new UI change to cut the clutter and manage Outlook web in a better manner, it is not known yet when it will become available publicly.
