I don't think Exchange 2007 information store is reporting correctly.

OK. i was doing my weely restore. Not sure how to explain this so i'll just try. I have one user (probably more thinking about it) who's entire email isn't showing. Example, basic, is he has 20 folders, but the restore only shows 5. He hasn't had only 5 for 2 years. So I decided to go and re create the job. However when I go to select information store, the database shows a size of 0. I've attached a screen shot.:

I can't dig into the mailbox database to select specific users. So to start I should say my question is: what is going on with this, why can't I drill down? I'm looking online while waiting. TIA.
