I used to work on one of the internal IT helpdesks at Vodafone UK.
They use a product called KVS Vault which uses separate servers to act as like a secondary storage area for people who've gone over their Exchange mailbox limit.
I got an e-mail from one of the sheep asking for a KVS Fault, referenced MULTIPLE times throughout the e-mail, in the subject line and the body text, so it COULDN'T have been a spelling mistake!
Far be it from me to argue with our "valued customers", I sent the following IM over to a colleague:
"Dave, do me a favour mate? Ask one of the techies in Newbury to go and kick the KVS boxes a few times, will you?"
He appeared at my desk some 5 minutes later looking rather confused.
