Attachment Content Type PRODUCT :Microsoft Exchange PROD/VER:winnt:5.5 SP3 OPER/SYS: KEYWORDS:exc55sp3 kbExchange550preSP4fix kbExchange550sp4Fix kbgraphxlinkcritical ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Exchange Server, version 5.5 SP3, on platform(s): - the hardware: DEC Alpha - the hardware: Intel x86 ------------------------------------------------------------------------------- SYMPTOMS ======== Netscape Internet Message Access Protocol (IMAP) clients may be unable to determine the content type of attachments. The Netscape client cannot determine which application to start to open a particular attachment. In some situations, the file names of the attachments are not rendered in the e-mail client correctly. This occurs in Netscape Internet Message Access Protocol, Version 4rev1 (IMAP4) clients on computers that are running either UNIX or Microsoft Windows, and that are downloading e-mail from an Exchange Server 5.5 Service Pack 3 computer. This does not occur in the Microsoft Outlook Express IMAP client. RESOLUTION ========== To resolve this problem, obtain the latest service pack for Exchange Server 5.5.
