In my company, they are going the other way. I can only imagine they are giving in too much to IT.
In a company of about 10,000, they are insisting that everyone cuts back to 500 MB (1 GB for managers) for their e-mail accounts. There were zero limits in place before (which was a mistake on their part).
Oh, and they gave people two months (when the company is being restructured) to clean up their accounts. Many people have 10+ GB of e-mail. This is an electrical utility with lots of engineers. Some of the information should probably be stored elsewhere, but sometimes, it is just damn convenient to look up the answer to a question you've been posed before.
And, if you've got a few thousand engineering types... how much money do you save on IT vs. how much is spent managing that cap number? They never did release the projected savings... probably so people couldn't question them vs. the increased cost to every other part of the organization.
