Outlook 2013
The corrupt PST file sits on the desktop
The PST file has attribute "A1"
The PST file has security permission "everyone"
"everyone" has full control.
"everyone" has effective access.
"everyone" inherits nothing.

The files within the PST are visible but cannot be moved to another PST
The files within the PST can be moved to different folders within the same PST.
The files within the PST can be successfully opened and replied to from the corrupt PST.
The files within the PST can be successfully forwarded or deleted within the corrupt PST.
The PST cannot be exported.
When attempting to move a file from the corrupt PST to a different PST, the error message, Cannot move the items appears.

When attempting to move a folder, a different error message appears suggesting a top-level folder cannot be moved to one of its subfolders.

Appreciate any tips or tricks !
