Exchange 12 will ship only on DVD
KC Lemson wrote on the Exchange Team blog that Exchange 12 would only ship on DVD. I think this is a good move. In most environments in which I have worked, we copy the entire Exchange CD-ROM on to a shared folder anyway.
Microsoft's easoning behind the DVD-only media is that the "text to speech" engines each take up a couple hundred megabytes of disk space. Exchange 12 will use these text-to-speech engines to allow users to dial-in via phone to their e-mail server and have their e-mail read to them. Exchange 12 will not be release for at least 12 to 18 months. For the full text, see Exchange 12 will ship on DVD.
