Every AV scanning on ISA server scans just some things.
In another words traffic or data objects which are recognized by AV.
Show me any AV for ISA and I will show you how to bypass it with any
virus.
Of course they, ISA AV products, usually don't tell you what is not
scanned to keep you happy.
In case of OWA I would rely more on scanning on native email format
scanning on Mail server then scanning it on not native transport
protocol for these objects.
In Another words more not standard encapsulation == more probability AV
will not check some levels of message encapsulation.

Hi Jim,
But can't the AV access it during the bridging? The HTTP Security Filter
has access at the point.
Thanks!

Since OWA should be operating over SSL, this makes the virus scanning
nearly irrelevant.
You should investigate a virus tool for the Exch server instead.
GFI rocks, period.
This mail was checked for viruses by GFI MailSecurity.
