Charge them
I know this is a little late, but i just joined. I run a network of 5 departments, 3 companies and 400 people. Although everything is owned by one person, every department has a budget and IT charges each department based on their usuage.
I put it to them this way. Everything has a cost associated with it. You want more storage space, then it's going to cost your department more money. When i explained it this way to the owner and the VP's, they all understood and agreed with it.
For the general users: 20mb box limit and 5mb send/receive.
For the VP's and traveling sales people: 50mb box limit and 10mb send/receive.
Although i still get the occasional gripes, it's worked out very well. But then again, i do have upper management's support. Hope this helps.
