Fortunately, not much damage was done - just their Internet service provider cut them off.
More fortunately, I didn't install that Exchange Server so they couldn't blame me. It was a hassle to fix.
Later their Exchange Server bombed and had to be re-installed. Unfortunately, they didn't remember their company code, which means none of their email could be accessed.
After some study, I found a severe security flaw in Exchange Server that allowed me to extract the company code. I published that on the Internet and got a few emails of thanks for all the time I'd saved for administrators.
