In the course of a Public Folder migration, MigrationWiz was not able to locate a Public Folder mailbox on the destination.
Cause of Error
There are several reasons that a Public Folder mailbox is not found on the Destination. For example, failing to create a root level folder can cause this error, as can failing to properly configure the administrator account on the Destination.
Review your configuration of the migration Destination, as well as reviewing the credentials provided on the Destination Endpoint. Be sure there is a Public Folder mailbox configured for the Public Folders.
