I have recently installed a new exchange 2007 server on a windows 2008 server. I then migrated the mailboxes from a Windows SBS 2003. After the mail boxes were over the Store.exe would continue to eat memory until it ran out and crash the server. It would happen when the maintenance job would run at 1:Am it would take more memory until about 5AM when it would crash. I have install service pack 2 and updated the network card drivers but still have the issue. Any help would be appreciated.
