IMailbox::Rootfolder does not work and returns error code 80040e19 if there is no proxy address for the user in the following format
where name is the value in the user's mailNickname attribute and domain is derived from the value in the user's homeMDB attribute.

The error message for error code 80040e19 is:
No key matching the described characteristics could be found within the current range


Rootfolder builds the URL based on information it reads from the user's mailNickname attribute in Active Directory. Before Rootfolder returns the URL, Rootfolder tries to bind to the URL to validate it. The Bind operation validates a URL by searching for users who have matching proxy addresses. Because the information contained in the mailNickname attribute is not guaranteed to match a user's proxy address, this search may not work. If this search does not work, Rootfolder returns error 80040e19.


To resolve this problem, obtain the latest service pack for Microsoft Exchange 2000 Server. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

NOTE: Because of file dependencies, this update requires Microsoft Exchange 2000 Server Service Pack 2.


Add a proxy address to the user for which Rootfolder fails that matches the name in the mailNickname attribute.


Microsoft has confirmed that this is a problem in Microsoft Exchange 2000 Server. This problem was first corrected in Microsoft Exchange 2000 Server Service Pack 3.
