Microsoft is planning its own unified mailbox feature named Linked Inbox.
The software giant revealed the feature in a press image sent to media outlets in New Zealand according to Neowin. Linked Inbox is expected to eclipse current unified mailbox features on rival platforms. It’s rumored that Linked Inbox will allow Windows Phone 7.5 owners to group specific email accounts into a single Inbox but also allow users to filter out others. The new virtual Inbox can then be pinned to the home screen of Windows Phone 7.5.
Microsoft is also making a minor change to the People Hub UI to include large and small picture support on its live tile. The company is making a number of large number of improvements for its “Mango” release and plans to unveil more at a VIP event on May 24.
Microsoft is currently hard at work on “Mango”, its next major release of Windows Phone. Microsoft has promised to ship “Mango” later in the year. “Mango” is currently in the early beta stages at Microsoft, built as 7.1 currently. The company revealed a number of new features in February that will ship as part of its Windows Phone point release later this year. Nokia is also reportedly waiting for the next release of Windows Phone before it unveils its first Windows Phone device.
