I see between 50% and 100% overhead at most of my medium-to-large clients; 
depending on whether they use PFs or SharePoint for shared calendars or they 
use resource mailboxes.

Making that kind of change (and what it would cost to change) is a typical 
piece of the in-source vs. out-source discussion.

Subject: Normal, or out of whack?

We employ about 350 people and have a few dozen contractors. Auditing Exchange 
for outsourcing, we have 475 mailboxes and 190 service account/resource 
mailboxes. 350 employees but shelling out for 650+ mailboxes just seems wrong.

Those numbers seem out of control to me - what kind of numbers/ratios do you 
guys se at your org's?
