An Outlook calendar appointment is not visible in the Day, Week, or Month view when you create the appointment by using WebDAV in Exchange 2000

When you create an appointment by using Web Distributed Authoring and Versioning (WebDAV), in the context of a delegate user, another delegate user may experience all the following symptoms when that delegate user views the mailbox owner's calendar:
  • The appointment does not appear when Microsoft Outlook is in the Day, Week, or Month view.
  • The appointment appears correctly when the appointments are sorted by category.
  • The appointment appears correctly when the delegate user views the appointment by using Microsoft Outlook Web Access (OWA).
This issue occurs if you do not explicitly set the dispidRecurring MAPI property in your program. When a schema name in your program is not specified, Outlook makes assumptions about the schema properties. Therefore, appointments that you create programmatically may not appear consistently when they are viewed in Outlook.
To resolve this issue, specify the dispidRecurring property in your program. The following code excerpt illustrates how to set this MAPI property.

Note You must include the data type namespace:
"xmlns:dt=""urn:uuid:c2f41010-65b3-11d1-a29f-00aa00c14882/""" & _

In this code excerpt, the following item specifies the dispidRecurring property:
"<mapi:0x00008223 dt:dt=""boolean"">1</mapi:0x00008223>" & _
This excerpt sets the MAPI property to 1 (TRUE) to create a recurring appointment. To create a non-recurring appointment, set this property to 0 (FALSE).
