During a Public Folder gathering you may receive this error: An error occurred in the enumeration of Organization Public Folders.
Error Code: 8004010F, Message: Unable to traverse subfolders. Failed to open the entry ID for "Folder Name". Not found. This is an unknown MAPI error (0x8004010f).
Open Outlook and select properties on the folders where this error is occurring. Under Administration, the folder maybe set to "Owners only". Changing the setting on "This folder is available" to "All users with access permission" resolved this error.
