I am tasked to find the average mailbox size of a general Exchange end-user in a mid-size company that is equivalent to one that I work for: 700 to 800 employees with approx. 550 to 600 email accounts.
We are trying to come up with a policy to ?encourage? people start cleaning out and deleting unimportant items and archiving the important ones from their inbox and sent items box. Since implementing Exchange 2000 (which was migrated from Groupwise), our storage has grown exponentially in the last two years! We have people that have not cleaned out their inbox in the last five years, and others that are using it for project management / document storage. So, you can imagine all of the same CAD files, pictures, movies, songs, jokes, etc. that are stored in multiple mailboxes throughout our company! We have some users that have a 10-15 GB mailbox size, so we must get a handle on this!
So, if I can get an idea what the average mailbox size of a ?normal? end-user using Outlook / Exchange for a company our size, it will help us develop a strategy to manage our Exchange 2000 server more efficiently.
PS: Moving to Exchange 2003 to help manage our end-users' mailboxes is not an option. We JUST migrated to a pure Windows 2000 server environment from Novell in the last 6 months, and that was a 2.5 year project! More-then-likely, our next Exchange server will be Exchange 2008 using Windows 2008, or something like that.
