The information in this article applies to:

- Microsoft Exchange Server, version 4.0 
- Microsoft Mail Windows 3.x Client 
- Microsoft Schedule+, version 1.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

Assume that a user on a Microsoft Mail postoffice (PO1) sends a Schedule+
meeting request to a user on Microsoft Mail PO2 and another user on Microsoft
Mail PO3. When printing the meeting request, the user on Microsoft Mail PO2's
WHEN field is printed, but the user on Microsoft Mail PO3 does not see a WHEN
field when printing the meeting request.

This problem occurs when you are using the following messaging architecture (the
important link being that Microsoft Exchange Server is the backbone for the
Microsoft Mail environment):

  MSMail PO1 <-->
  Exchange Server1 <--> Exchange Server2 <--> MSMail PO3>
  MSMail PO2 <-->

CAUSE
=====

A property of the Schedule+ message is not properly converted during the
conversion from FIPS to MDBEF, and this property is dropped.

The message going from PO1 to PO2 does not have to traverse the Microsoft Mail
Connector Interchange (MSMI), and therefore does not experience this problem.

The message going from PO1 to P03 must traverse the MSMI, and is therefore
converted once it is on its way into Microsoft Exchange Server, and once again
on its way out of Microsoft Exchange Server and back to Microsoft Mail.

When a message from Microsoft Mail is sent, it uses a FIPS message format.
Microsoft Exchange Server uses a message format called MDBEF, and all messages
coming from Microsoft Mail must be converted from FIPS to MDBEF by the MSMI.
When a message is sent from Microsoft Exchange Server to Microsoft Mail, it is
converted from DBEF format to FIPS format.

The property is not properly saved or converted from FIPS to MDBEF when coming
into Microsoft Exchange Server through the MSMI; therefore, when it is converted
back to FIPS when it leaves Microsoft Exchange Server through the MSMI, the
property is not retained.
