I have an exchange 2003 service pack 2 on a windows server 2003. My problem is with the Background Cleanup. Best practice analyzer says that background cleanup isn't running. I checked the registry and the correct registry values are set. There are some mailboxes where the size increases even though the messages are moved to personal folders. My best guess is that the background cleanup isn't actually running. Is there a way to reinstall the background cleanup? Also there are several private-<GUID> values in the registry and there is only one Mailbox store. Is it possible that there isn't a registry value for my private mailbox store? Anyway to find out what the GUID is so this can be checked to make sure it exists in the registry.
Thanks for any help
