Paul Bryan, Microsoft’s senior director of business experiences product management for Windows Phone, has written a blog post that details Windows Phone Mango’s business productivity features. The update, which will be discussed in deeper detail during a press conference in New York City on May 24th, will include pinnable email folders for quick access from the homescreen, conversation view in email, server search, and a new Lync application for business chat users. Bryan also said there will be added capabilities for IT departments, including complex password support, information rights management support, and the ability to access hidden corporate Wi-Fi networks. “This week, we expect to exceed 16,000 apps available in the Windows Phone Marketplace,” Bryan added. We’ll be reporting live from Microsoft’s press conference on the 24th.
