When sending an email message, it's a good idea to ask yourself what would happen if its contents were made public. If public disclosure would be harmless, go ahead and click Send. But if it would be embarrassing or bad for business, you might consider taking some protective measures.

One way you can protect yourself against unintentional disclosure of email content is by using Microsoft Outlook's Information Rights Management (IRM) feature.

With Information Rights Management, you can place various restrictions on an outbound message. For example, you can prevent the message from being forwarded or printed. You can even keep someone from copying and pasting the contents of the message into another document.

Before you get too excited though, Information Rights Management isn't foolproof. It only works if recipients are using Outlook 2003. If they happen to be using Outlook 2000, Eudora, Outlook Web Access, or anything other than Outlook 2003, they will not be able to open the email.

The good news is that Microsoft will likely build IRM into future versions of Outlook and Exchange Server. This means that, even though there are a limited number of recipients that recognize IRM permissions today, that number will increase over time as more people upgrade to newer versions of Microsoft Office.

In the meantime, there is an IRM add-on for Internet Explorer that allows recipients who do not have Outlook 2003 to view IRM-protected documents.

Sending a message using Information Rights Management

You will now be able to send the restricted message.

MEMBER FEEDBACK TO THIS MICROSOFT OUTLOOK TIP

When I click on File in a new message in Outlook 2003, there is no Permissions option. Please advise. Thanks.
—Edwin T.

******************************************

It sounds like the underlying service is missing. You can get Microsoft's Rights Management Services here.

******************************************

Does the recipient need to have Information Rights Management (IRM) installed just to view a message sent with restricted permissions? Is there an additional Windows server-side component that needs to be running?

In testing IRM out, I set it up on my Outlook 2003 client using the 10 steps provided in the article.

The recipient of the test message was unable to simply view the message. He got prompted to install IRM on his PC, and even after doing so, was not able to open the message.

Any feedback would be appreciated.
—Dustin F.

******************************************

Yes, the recipient does need to have IRM running. If IRM is not running, the recipient will be prompted to install it and should then be able to view the messages.
