Exchange 2007 was the first release of Exchange to include Unified Messaging (UM) and this was the first time many of our customers started considering replacing their existing voice mail systems with UM. As with any new technology, many have sent in questions or concerns regarding the legal implications of UM, and how to control the voice mail messages once they're inside Exchange. If you aren't familiar with Exchange UM and the benefits it provides to both end-users and IT professions, please check out more information here: http://www.microsoft.com/exchange/evaluation/unifiedmessaging/default.mspx . However, some companies have been hesitant to store voice mail and e-mail in the same system, fearing that it will create increased legal risk by making voice mails more "discoverable" or somehow less manageable. We got this initial feedback during our TAP and beta trials of Exchange, so we worked with the law firm of Covington & Burling LLP. They studied this problem and created a white paper to summarize their findings. If you read through the white paper, you'll notice two things. First, the white paper concludes ".that no aspect of Exchange alters, by increasing or decreasing, the record retention obligations of these organizations in the U.S. or E.U. ." That is, if a company is obligated to retain voice mail messages, it doesn't matter if they're stored in Exchange 2007 UM or somewhere else - they still need to be retained. Likewise, if voice mail messages have been deleted in the normal course of business prior to an obligation to retain them, the fact they were in Exchange 2007 UM doesn't create a new obligation to retain where no obligation existed before. Secondly, the white paper notes that Exchange 2007 Unified Messaging offers significant advantages for a company that may need to retain and produce voice mails. Features that were considered especially helpful included being able to visit a single system to access, query, and produce both voice mail and e-mail; and having a single repository (rather than multiple repositories) to apply retention policies.
