Synchronization of Distribution List is not populating with Public Folders as members
If a mail enabled public folder belongs to a Distribution List, the Directory Synchronization cannot synchronize the membership of Public Folders within these groups.
Obtain a copy of the PFsyncX utility to synchronize the Mail enabled Public Folder's "Member of" attribute to the target.
NOTE: To obtain a copy of the Utility, you must contact your Professional Services or Account Manager. Support is not able to provide a copy of the Wizard or support for the Wizard.
