Another Exchange question here...
I am trying to get my user base to cleanup their outlook mailboxes and using the command Get-Mailbox Statistics in the Exchange Management Shell to pull their mailbox sizes into a .csv so I can then pull it into Excel.
However, I know that Exchange 2007 has Single Instance Storage so that it doesn't store the same message twice in the same database. So, when exchange tells me that Bob has a 2GB mailbox and Bill has a 1GB mailbox, is it possible that some of their. "shared" emails are contributing to the reported size of one mailbox, but not the other?
And if they are being reported under Bob's mailbox, and bob deletes the message, would it them inflate Bill's mailbox?
I have a couple of user's whose mailboxes have increased dramatically since we started this process and this is my only explanation.
Or maybe it would attribute the shared message to both mailboxes and it's not an issue?
