Public Folders provide an easy and convenient way to share content with multiple users and user groups in an organization. All users have access to Microsoft Outlook to work with their emails and mailboxes, so adding Public Folders as an additional feature to the product they know very well is convenient and efficient.
Deployment and management of Public Folders are also simple and clear for Exchange Administrators since they don’t need to use regular mailboxes for that purpose and configure sophisticated permissions to give control of those mailboxes to multiple users.
