Microsoft shared even more details of the Windows Phone Mango update at the
TechEd 2011 conference being held in Atlanta this week. A couple of the new
productivity features are things I have been hoping for and again serve to
convince me to stick with Windows Phone as my primary platform.

The upcoming features announced today include:

• Pinnable e-mail 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 e-mail: E-mails 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.
• 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 for Windows Phone will provide business
  Instant Messaging and presence so you can stay connected to your colleagues
  while on the go. The Lync app will be a free download from Windows Phone
  Marketplace with access to Lync services that are enabled by your
  organization.
• Complex password: Additional corporate compliance
  capabilities with support for alphanumeric passwords
• Information Rights Management: Support for protecting
  e-mails and Office documents
• Support for Hidden SSID: With support for access to hidden
  corporate Wi-Fi networks, IT organization can stay on top of their game
  providing access to information while meeting corporate
  requirements.
