Outlook View Control Vulnerability
My vacation last month was interrupted by news of yet another
HTML-related vulnerability in Microsoft Outlook, this one tied to
the Outlook View Control (OVC). The OVC, which is integrated into
Outlook 2002 and can be added to Outlook 2000, is an ActiveX control
to display any Outlook folder. The vulnerability makes it possible
for allow malicious code to do almost anything with your Outlook
data, including deleting items and harvesting e-mail addresses from
messages. A patch is expected shortly.
Whether or not you need to worry about this depends in part on
your version of Outlook. The security features in Outlook 2002
protect against malicious code exploiting the Outlook View Control
in an HTML-format mail message. However, Outlook 2002 users still
are vulnerable to the use of the control in a web page. Therefore,
for safety's sake, you should disable the ability of ActiveX
controls to run in pages in the Internet zone in Microsoft Internet
Explorer by following the instructions in the article "OL2002: The
Outlook View Control Exposes Unsafe Functionality" at
http://support.microsoft.com/support/kb/articles/Q303/8/35.asp.
Outlook 2000 does not include the Outlook View Control as an
integrated feature, but many organizations have deployed Team
Folders or digital dashboards that include the OVC. If the file
Outlctlx.dll is present on your system, then you are vulnerable. For
protection, you should adjust the security zone settings for Outlook
as described at
http://www.slipstick.com/outlook/antivirus.htm#zones, unless you
have already installed the Outlook E-mail Security Update or Office
2000 Service Pack 2 (which adjust the zones settings automatically).
You should also disable the ability of ActiveX controls to run in
pages in the Internet zone by following the instructions in the
article "OL2000: The Outlook View Control Exposes Unsafe
Functionality" at
http://support.microsoft.com/support/kb/articles/Q303/8/33.asp.
Managing extra mailboxes in Exchange
From time to time, I want to highlight solutions developers who
really seem to understand what people want from Outlook. One such
developer is Victor Ivanidze, whom I met while I was living in
Moscow and whose web site at
http://victori.hypermart.net/ features COM add-ins for Outlook
2000 and 2002, sample forms to add header fields to Internet
messages, and various other tips.
Lately, Victor has focused on one of the stickier issues in
Outlook in an Exchange environment -- working with a secondary
mailbox. As you probably know, with proper permissions, you can open
another mailbox and see all its folders, respond to messages in its
Inbox, etc. A typical example is a Support mailbox that help desk
staffers access in addition to their own mailboxes.
The hard part comes when you want to ensure that messages sent
from the other mailbox have the right From address and are stored in
the other mailbox's Sent Items folder. I wrote an article a few
years ago (http://www.windowsitpro.com/Articles/Index.cfm?ArticleID=4855)
on various ways to meet those goals and concluded that it was easier
to abandon the shared group mailbox approach and use a public folder
instead.
Victor has breathed new life into the group mailbox approach,
however, by offering two COM add-ins that together make it possible
to handle a secondary mailbox's messages seamlessly. RightFrom is a
utility that automatically fills in the correct From address when
you reply to or forward a message in the other mailbox. The second
utility, UniSent, ensures that those replies and forwards are stored
in the Sent Items folder of the other mailbox, not in your own
mailbox. It also puts items that you delete from the group mailbox
into the group mailbox's Deleted Items folder.
Remember that, if you're implementing a group mailbox, there are
two different ways to set permissions to allow other users to send
on behalf of the mailbox. If the Exchange administrator grants Send
on Behalf Of permission to the Support mailbox, outgoing messages
will show both the actual sender and the Support mailbox. If you
want to hide the actual sender's name and address, you need to grant
Send As permission to the user's Windows account.
MEC Awards 2001
Once again, Microsoft is seeking the best applications for
Exchange and best solutions that leverage Exchange features. You can
nominate your company or your favorite tool in any of 10 categories
at
http://www.microsoft.com/corpevents/mec2001/awards.asp. Winners
will be announced at MEC in Orlando in October.
MEC registration open
Registration is now open for MEC 2001 in Orlando, Florida, Sept.
30 - Oct. 4. Exhibits open Sept. 30, with conference sessions
beginning Oct. 1. Microsoft is now billing MEC as the "premier
Exchange, Windows, and .NET Enterprise Servers event." Register at
http://www.microsoft.com/MSCorp/corpevents/mec2001/reg.asp
by August 24 to get a discount.
MEC Europe will take place in Nice, France, Nov. 6-9. The web
site at
http://www.microsoft.com/europe/mec/ is expected to
have registration details at the end of June.
MEC Japan will be in Tokyo, Oct. 29-30 (a change from the August
date that Microsoft gave earlier). No registration site yet.
Office Developer Connections Conference
I will be speaking on Outlook development at the Office Developer
Connections conference Oct. 4-5 in Scottsdale, Arizona -- covering
Outlook security, Outlook reports, and what's new for developers in
Outlook 2002. One of the sample applications that I'll be showing
adds "merge to HTML e-mail" capability to Office XP, without raising
the Outlook security prompts.
