Do you know how much big is your Exchange Server Offline Address Book (OAB)?

Recently Microsoft Exchange Team published a blog article on MET blog describing the insights about OAB network bandwidth sizing and utilization, this is a great resource with respect to both initial planning and solution sizing days, and as well as routine performance monitoring and enhancement, where an Exchange Administrator can look at his growing OAB size and see the appropriate network bandwidth required for his clients to download the OAB over slow network links.

Cheers!
