DOCUMENT:Q312269 22-JUN-2002 [exchange] TITLE :XADM: Duplicate Calendar Entries w Update Method & Outlook 2002 PRODUCT :Microsoft Exchange PROD/VER::5.5 SP4 OPER/SYS: KEYWORDS:kbExchange550preSP5fix ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Exchange Server, version 5.5 SP4 - Microsoft Outlook 2002 ------------------------------------------------------------------------------- SYMPTOMS ======== After Microsoft Outlook 2002 receives a meeting request in the Inbox, Outlook 2002 may create a duplicate calendar appointment. If a Collaboration Data Objects (CDO) application calls GetAssociatedAppointment and places a meeting in your calendar first, and then you click the meeting request in Outlook 2002 to open it, a duplicate appointment is created. Outlook 2000 does not create duplicate appointments in this scenario. CAUSE ===== This problem can occur if CDO was not updated to reflect the way that Outlook 2002 uses index PR_OWNER_APPT_ID to determine duplicate appointments. RESOLUTION ========== A supported fix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Only apply it to systems that are experiencing this specific problem. This fix may receive additional testing. Therefore, if you are not severely affected by this problem, Microsoft recommends that you wait for the next Microsoft Exchange Server 5.5 service pack that contains this fix. To resolve this problem immediately, contact Microsoft Product Support Services to obtain the fix.
