Mailbox Resources Incorrectly Display the "total k" and "total items" Columns for Connector Mailboxes

On the Mailbox Resource tab in the private information store properties, Internet Mail Services may contain a large number in the total K column. However, if you view the Mailbox Resources container under Private Information Store, Internet Mail Services has 0 in the total k column.

When Admin.exe needs to display the mailbox size for the connector's mailbox, a Messaging Application Programming Interface (MAPI) property PR_EMAIL_ADDRESS is used to obtain the mailbox name. This problem can occur if the mailbox is an Internet Mail Service mailbox; Admin.exe ignores the size of the mailbox because the size is a useless number. Unfortunately, the PR_EMAIL_ADDRESS property is not included (by default) when constructing the query property array, so Admin.exe does not realize that the mailbox is a connector mailbox and displays the mailbox's size.

To work around this problem, add the Full mailbox Directory Name column to the display header.

Microsoft has confirmed that this is a problem in Microsoft Exchange Server version 5.5.
