SYMPTOMS
Outlook can sometimes produce a duplicate appointment for a meeting request if you send the meeting request as one of the occurrences of a recurring appointment that was not made as meeting item. This behavior can occur when you are using Outllib.dll version 8.5.6119 or later.



CAUSE
Outllib.dll version 8.5.6119 or later uses a PR_OWNER_APPT_ID property in restriction when searching an associated appointment item. However, after the recurrence item is not made as meeting item, the item does not have the PR_OWNER_APPT_ID property. If you use Outllib.dll version 8.5.6119 or later causes Outlook not to search the associated appointment item with the PR_OWNER_APPT_ID property. As the result, the meeting request is recognized as a different meeting from the original appointment item, and the meeting is duplicated. This behavior is corrected by Outllib.dll version 8.5.8028.0.
