This policy setting controls whether 2007 Office applications notify users about unsafe hyperlinks.
Links that 2007 Office considers unsafe include links to executable files, TIFF files, and Microsoft Document Imaging (MDI) files. Other unsafe links are those that use protocols considered to be unsafe, including msn, nntp, mms, outlook, and stssync.
If you enable this policy setting, unsafe hyperlink warnings are suppressed for all users.
If you disable this policy setting, hyperlink warnings cannot be suppressed by any means. 2007 Office users will be notified that links are unsafe, and must enable them manually to use them.
If you do not configure this policy setting, 2007 Office applications notify users about unsafe hyperlinks and disable them until users enable them.
