Public Folders have long been the neglected, unloved Exchange Server feature many IT professionals wish would go away. They’ve stayed around for longer than many have expected because they work well from an end user’s perspective.
If an organization is moving to Exchange Server 2013, some back-end issues, such as Public Folder replication, become history. Modern Public Folders allow Public Folders to be stored within Mailbox Databases and inside Public Folder mailboxes.
Migrating Public Folders to Exchange 2013 is a tough task. Before cracking open the champagne, admins need to be aware of the limitations of migrating Public Folders that could make them wait a while longer before a migration, reorganize their Public Folder infrastructure before attempting to migrate it — or leave Public Folders behind for good. Take each of these issues into account before considering a migration.
