Right. So, buy allowing PST's a 100 MB mail to 10 people would take 1000MB of disk space on a file server/hard drive somewhere. It only takes 100MB on your server. That's a savings to IT of 900MB of storage.

Fair enough.  But you want the individual mailbox size to be representitive of reality if that mailbox was separated from the store.  The individual mailbox size is not intended to reconcile to store size.  SIS is a storage benefit at the server.
 
If you really wanted, you could check out the SIS ratio perfmon counter and see what the ratio is.  Perhaps it's really high in your company.

This is what happened William: 
 
I was continuing my war on Pst's and touted the value of SIS as one of my weapons.  My boss asked me,"If SIS works like that, why does everyone's mailbox get incremented equally when  one user sends 1 attachment to many recipients?  If you are only putting one 100 Meg object into the store, the size of that object should be distributed amongst the recipient equally."  I didn't have a good answer for him so it got me wondering. 
 
I am in the middle of a holy war regarding pst's and mailbox restrictions.  Users hate both and they are using this principle to fight with me.  Believe me, I didn't want to get into a dissertation about the technical aspects of SIS, put these damn users don't give up!

Based on that, someone's mailbox size could grow 90MB without them sending or receiving additional data.
 
You are hoping to reconcile the mailbox contents to the byte to store size?

Subject: Theoretical question concerning SIS

Happy Friday everyone, came up with a thought this morning and was wondering if anyone knew the answer to the following situation.
 
1.  Exchange 5.5
2.  Outlook 2000 clients
3.  No PST's.
 
User A sends 1 100 Megabyte file to ten users.  Because of SIS only 100 Megs of space was used on the Exchange server, not 1000.  Each user will show that they are using 100 Megs of space, but my understanding is that there is only one 100 Meg file with 10 mailboxes pointing to it.
 
Assuming I am correct with everything that I wrote:
 
Why doesn't Exchange charge, and Outlook display 10 megabytes to each mailbox?  After five people delete the attachment (really the pointer to the SIS 100 Meg object), the remaining five  would each be charged 20 megabytes.  That make any sense?
 
My first instinct is that it would be just to damn complex.  Any thoughts Guru's? 
 
By the way, this came up during an argument about PST's after I explained the benefits of SIS and using reasonable mailbox limits.  Have a great weekend everyone.
