DOCUMENT:Q187970 07-MAY-1999 [exchange] TITLE :XCON: Unicode Message with TNEF Causes Information Store to Stop PRODUCT :Microsoft Exchange PROD/VER:WINDOWS:5.0,5.5 OPER/SYS: KEYWORDS:exc55sp2fix ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Exchange Server, versions 5.0, 5.5 ------------------------------------------------------------------------------- SYMPTOMS ======== If you send a Unicode message that contains transport-neutral encapsulation format (TNEF) information to a Microsoft Exchange Server computer, the information store may stop unexpectedly.

However, if the message contains TNEF information, non-Unicode text properties may be set on the message. This inconsistency between the message's codepage and text properties causes the information store to stop unexpectedly.
