Over the last 3 years the number of email users at the organizations I serve (Ministry Health Care and Affinity Health System) has increased 17%. In 2008 we had 15,900 mailboxes. Today we have 18,578 mailboxes.
Over that same period our total email storage has increased from 1.5 Terabytes to 5.6 Terabytes. That is a 273% increase.
Interestingly, the top 7% of the mailboxes (1,300) account for 55% of the total storage. My mailbox is the 88th largest (5.3 Gb), this includes deleted and sent items, which I cling to.
