I agree it's not written in the clearest way, nor verifiable (though Stefano Marinelli does seem to be a semi-public figure in the online IT community, so it's not some anonymous blog).
>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.
The price was reasonable given the average quotes received by similar entities and the prices on the market, but it was absurd when considering the service provided. Perhaps I didn't make that point clear, and I'll likely modify it slightly. The concept is that the price, which was initially acceptable to them, was in fact absurd when viewed in terms of what was being provided.
