The underlying server infrastructure was solid, but the VM with Exchange was now old. The entire setup would have needed to be redone. The second paragraph, on the other hand, says that the quote was "acceptable" for them, knowing the average costs for that service. But it was also very high, even in the opinion of the IT manager.

This isn't AI slop. These are real-life experiences. The goal is to raise awareness that open source doesn't always and necessarily mean freedom: lock-in exists.
