SYMPTOMS
========

Users cannot log on to their Exchange 2000 mailbox with Outlook 2000 for the
first time. Actually, Outlook starts without error, and users can see default
folders, but when they attempt to open one of the folders, they receive the
following error message:

  Unable to expand the folder. The set of folders could not be opened. The
  attempt to log on to the Microsoft Exchange Server computer has failed.

In the Application event log, there are events which suggest a successful logon,
but there is also the following event:

  Event ID: 9562
  Source: MSExchangeIS
  Description: Failed to read attribute msExchUSRAccountControl from active
  directory for /o=Org/ou=Administrative Group/cn=Recipient
  Container/cn=Mailbox.

CAUSE
=====

The schema for Exchange 2000 was not properly extended when you upgraded from
Release Candidate 2 (RC2) to the Release to Manufacturing (RTM) version.
Specifically, you did not re-run forestprep with the RTM version of Exchange
2000 Setup. As a result, the msExchUSRAccountControl attribute was not added to
the schema. This is a required attribute that was added post-RC2.

RESOLUTION
==========

After you run /forestprep, which forces replication to the child domain, run
/domainprep in the child domain, and rebuild the Recipient Update Service
objects. Then you can log on to your mailboxes.
