So yet more Windows Phone 7 Mango updates have been revealed, after the unofficial leaks last week, this one comes in the form of an official post on the Windows Phone Blog by Paul Bryan leaving us wondering if there will be anything left to announce at the event on May 24th.

While there are a wide range of new features in Mango that you’ll hear more about in the coming weeks and months, at TechEd we’re highlighting a number of new capabilities designed to help you stay productive on the go.

  • Pinnable email folders: Pin a folder to the start screen for quick access. This could be an email folder for a specific project, from a specific group or person (like your boss), or an RSS feed you’ve set up in Outlook.
  • Conversation view in email: Emails in your inbox are organized by conversation, bringing replies to a thread into a consolidated view so it’s faster and easier to stay on top of the conversation.

Threaded email, coming in the next version of Windows Phone, makes it even easeir to keep track of who said what.By popular request, the next version of Windows Phone also makes it possible to read rights-managed emails.

  • Server search: Search your email server (e.g. Exchange Server) for older emails no longer stored on your phone, giving you ready access to all of your mail.
  • Lync: Lync Mobile brings the Lync experience to Windows Phone customers by delivering Unified Communications capabilities, including instant messaging and the ability to see the presence of your co-workers. The Lync app will be a free download from Windows Phone Marketplace and will be enabled with support from your business organization.

Lync Mobile brings Microsoft Lync to your phone so it's easy to keep in touch with co-workers.

In addition to helping you stay productive, Mango also includes new capabilities for IT. With new features such as complex (alpha-numeric) password support, Information Rights Management support for protecting e-mails and Office documents, and support for access to hidden corporate Wi-Fi networks, your IT organization can stay on top of its game—providing you access to information you need while meeting corporate requirements.
