I am running Exchange Server 5.5 on an SBS server. When I look at the total of my Mailbox Resouces and then the size of my priv.edb file, they are not even close. My priv.edb file about 20 times bigger than the collective total of my mailbox resources. Even when I clean up my mailboxes, run the on-line defragmentor, and garbage collection, the priv.edb file will not decrese or change in size. Can someone tell me what is happening and what I can do to fix it?? Thanks.
