>So we have just learned in paragraph 1 that the current system is dated and full of security holes and missing features. In paragraph 2 we have learned that the current system's infrastructure is "solid" and "working fine".
This confused me too, until I realized that he probably meant that his company set up the hardware infrastructure ("reputable IP classes, redundant datacenters"), but doesn't manage the software. Otherwise, why shred your own credibility from the first sentence by crapping on the "ancient," "insecure," and "ineffective" Exchange server?
>How can the price be both "reasonable" and "absurd?"
Agreed, this part makes no sense.
