I think I have resolved this by other means - it seems to be related to the properties &quot;DeliveredDate&quot; and &quot;PostedDate&quot;. &nbsp;It has to be PostedDate if you are the organizer, or DeliveredDate if not. &nbsp;Screwy.

I maintain an application that creates Notes calendar entries, via the C API. &nbsp;I have a case where I am creating a repeating calendar entry. &nbsp;I do this by creating two documents, a parent and a child. &nbsp;The resulting meeting looks fine, as far as recurrence and other data. &nbsp;The problem I have is that it cannot be modified (rescheduled or deleted). &nbsp;I get the error message &quot;you must select an instance document to perform these actions&quot;. I have read the IBM technote on this error message, but I don't really understand how it would apply to me, with regards to what modifications I need to make to the parent or child documents. &nbsp;As far as I can tell, the entries that I create are identical to those created natively in the Notes client, but I don't have this problem with the native document. &nbsp;Can anybody shed some light on this problem?

You must select and instance document...

Lotus Software produced the Lotus 1-2-3 spreadsheet program, and later developed Lotus Notes, a groupware and email system. Following its acquisition by IBM, the Notes and Domino client/server collaborative platform were expanded to include functions such as email, calendars, to-do lists, contacts management, teamrooms, discussion forums, file sharing, microblogging, instant messaging, blogs, and user directories. IBM also release SmartSuite, a comprehensive office suite, and followed that with Symphony, unrelated to the Lotus suite of the same name.
