Public Folders in New Outlook

This is from the Microsoft website: "Public folders are designed for shared access and provide an easy and effective way to collect, organize, and share information with other people in your workgroup or organization.
Public folders organize content in a deep hierarchy that's easy to browse. Users discover interesting and relevant content by browsing through branches of the hierarchy that are relevant to them. Users always see the full hierarchy in their Outlook folder view. Public folders are a great technology for distribution group archiving. A public folder can be mail-enabled and added as a member of the distribution group. Email sent to the distribution group is automatically added to the public folder for later reference. Public folders also provide simple document sharing and don't require SharePoint to be installed in your organization. Finally, end users can use public folders with the following supported Outlook clients: Outlook 2010 or later and Outlook on the web (formerly known as Outlook Web App), but with some limitations."

Clearly Public Folders was intended to be the location to save shared email by team members. It needs to be a high priority to maintain that system or provide an alterate way for team members to collaborate.
