Just curious as we have a compliance need to provide Encrypted email. We are hoping to use this also to get an Exchange 2007 upgrade out of the way. I've been told there is a way using a cert from a trusted root authority that you can encrypt email? Is this just internal? Can it be external and what might be the problem with this as I've for some reason never heard of it before now? If this isn't an option what seems to work best for you?
