Granular Exchange 2007 Restore and BE 15

Hi all.

We have a issue here, we can make backups without problems, our Exchange 2007 server has 3 databases and there's no problem do make backups. But, we can not make granular restores, when we start a new task to restore a user mailbox or other item BE doesn't show nothing, no users, folders or items.

We appreciate if someone help us.

Thanks.
