There
are 2 levels of file attachments for
Outlook Web Access. Level1 attachments
have file extensions that are prohibited
from accessing by OWA. Level2
attachments have file extensions that
can be accessed, but only if saved to
the client's file system first.
OWA is
installed with a default set of file
extensions for the two levels as shown
in the following registry keys:
