Mesasge removed from the system

Just want to understand how things work in the background for when a message is deleted.
If I had 30 message in my mailbox, obviously that is taking some space on the server database, now if I removed those message, completed, would that space be restored......or not...
I compare this to the term truncate, in Oracle when a truncate happens the file is deleted as well as the space on the harddisk is able to be used for content again, where as when deleted, yes the file is gone but that "space" is not accessible...
wondering how this works for Exchange 2000

Hi lobos,

The message is removed, but the space on the database isn't. Exchange will use the space, but won't shrink the database size unless you do an offline compression.

So if you delete 30mb of messages from your 45mb exchange database, the database remains 45mb in size on the hard disk, but all your messages will be deleted.

If I had 3000 items (looking in system manager) and I deleted 2000 items, why doesnt that number decrease?

Check that the items have been deleted from the Delete Items folder on the user's mailbox, otherwise the system takes a certain amount of time to update the DB. I haven't checked, but I think it's around 30 minutes before updating.
