SYMPTOMS
========

When you are using an Exchange or Outlook client, and you receive an encrypted
message sent from an Outlook 98 client, the message may be unreadable. Other
messages received with Key Management Server encryption are readable.

CAUSE
=====

Outlook 98 supports S/MIME encryption; Exchange and Outlook client versions
earlier than Outlook 98 do not.

WORKAROUND
==========

Messages sent from an Outlook 98 client to an Exchange or pre-98 Outlook client
should not be encrypted.
