Outlook / OWA attachments

[Guest]

When you open an email attachment, that document gets cached in a folder on
the local PC. Is there a way in OWA / Exchange 2003 to prevent attachment
caching?

We don't like the idea of leaving behind a cached attachment - especially on
a PC used in someone ele's office on the road.

I think there is a way to block attachments, but that will make OWA useless
-- at least for our needs.

I've seen plenty of references to a program called Attachview, which can
handle this issue. But I thought I would ask if anyone knows of a way to deal
with caching within Exchange / OWA 2003.

Thanks!

OWA doesn't work that way. It does not use the Outlook Secure Temp Folder.
It does, however, use the Temporary Internet Files folder because OWA is
just a web view of the Exchange mailbox. Once you're done, clear the
Internet Explorer temporary files.

Brian,

Thanks for the information. I cannot, however, rely on users to remember
that they should clear Temporary Internet Files. In fact, I can't rely on
them remembering HOW to clear them.

That's why I don't want the attachment cached in the first place. The
responsibility cannot be placed on their shoulders.

If there is no way to do it natively, I'll likely need the third-party
program I mentioned previously.

It's not the "attachment", per se that is being cached, it's all the web
pages the browser displays and it has nothing to do with Outlook Web Access
or Exchange. It's how web browsers work. Unless you have control over the
PC they're using, you can't change the browser settings.

If there is no way to do it natively, I'll likely need the third-party
program I mentioned previously.

If they're on the road, they should be connecting via a VPN that supports a
cache cleaner. Removing sensitive data fro the client PC will then be
automatic.
