Under Microsoft's Information Rights Management (IRM) system, users will be able to set restrictions on email messages to selectively prevent recipients from forwarding, copying or printing content. An email expiration feature also lets users set a deadline after which messages cannot be viewed.
John Barker, an IT specialist at law firm Last Cawthra Feather, warned that the technology could encourage users to become more blasé about the content of emails.
"If people think the rude email they sent would be de-activated, and therefore 'undiscoverable', they might be more inclined to send it in the first place," he said. "However, they are not going to get away with it, as the technology means the email will be recorded on the Exchange Server, or equivalent."
