I get this error when I try to share the users folder in exchange.
I found a document on this
You receive an error message when you try to open another user's folder even if you have owner permission in Outlook 2003

For a Microsoft Outlook 2002 version of this article, see 280945.
If you have the required permissions for another user's mailbox, and you try to access that mailbox in Outlook 2003, you may receive an error message that is similar to the following:
Unable to display the folder, cannot open the mailbox for this user because the user does not have a server mailbox.
This problem may occur when the two user accounts do not reside on the same Microsoft Exchange Server organization.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
I am on the same Microsoft Exchange Server organization.
We only have one organization.
Can some one please shed some light on this.
