In Exchange 2000, if the mailboxes are created but never logged into, they're not visible in ESM. How do I delete these mailboxes?

I believe the mailbox isn't actually created until they login, therefore if they haven't logged in there is no mailbox to delete. Are you deleting the user object in AD?

Hi, Please understand that the mailbox is not actually created until someone either sends a message to the email address or a user logs on with Outlook/OWA. So, it's just an AD account without mailbox. Thanks Allen

Yes, Its actually mailbox with non instance in MBX server database. for delete it just send one mail to this object and delete malbox after some time, Once you see Exchane task option when right click on AD account.Anil
