SQL Query to find archived messages & archive item size per mailbox user

Hi Guys,

I have a request to find a way to get information out of EV 10 about all the users archived and the items archived bases on size pr mail.
Advanced search does not give me what I need because EV Admin account does not have access to all archives.
So I belive only way to get what I need is thru SQL query.

I need to be able to get infomation on all mail archived pr user, and the size.
More spesific mail larger than 25MB.
And a way to export that information to a spreed sheet.

Anyone have an ide on how to create script like that

Thank  you :)
