- Microsoft Exchange Server, version 4.0

SYMPTOMS
========

When you use the Microsoft Exchange client to open a Public Folder (PF) that has
a special custom view that categorizes the folder content, the open attempt
might return the following:

  Error: Unable to display folder

CAUSE
=====

When a categorized view is added to a PF, the required columns are added to the
folder table in the Microsoft Exchange Information Store (IS) to support this
view. When we re-use this folder table, we assumed that all the columns needed
are already present in the IS. However, if this same folder table is used but
the sort criteria is different, the QueryRows call will not check to make sure
the columns needed for the new sort criteria are present. It only checks that
the columns needed for the categorization are present. So when QueryRows tries
to create an index to the sorting columns, the IS database (JET) returns a
JET_errColumnNotFound (this is translated as MAPI_E_CALL_FAILED).

STATUS
======

Microsoft has confirmed this to be a problem in Microsoft Exchange Server
version 4.0. This problem has been corrected in the latest U.S. Service Pack for
Microsoft Exchange Server version 4.0. For information on obtaining the Service
Pack, query on the following word in the Microsoft Knowledge Base (without the
