SYMPTOMS
You programmatically retrieve recurring appointments from someone else's calendar using the Outlook object model, and the start dates for all of the recurring appointments are the same.



CAUSE
The person did not give you full permissions to their Calendar folder

-and-

In your code, you used early binding on the AppointmentItem object variable.

NOTE: The properties that are read may also effect results, see the note at the end of the "More Information" section.



RESOLUTION
Late bind the AppointmentItem object variable. An example is provided after the "Steps to Reproduce Problem" section.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.



MORE INFORMATION
The problem does not occur in Visual Basic Scripting Edition (VBScript) since all variables are inherently late-bound. However, this problem can occur if you use Outlook Visual Basic for Applications or automate Outlook from another application that supports early binding.

This problem did not occur in Microsoft Outlook 97 and was introduced in Outlook 98 (8.5). The problem was fixed in later versions of Outlook 98, but for the correct start times to be returned, you must use early binding of the AppointmentItem object variable.

With respect to this problem, no changes have been made to Outlook 2000, which still requires the AppointmentItem variable to be late-bound.

 Create a new recurring appointment in someone else's calendar. Do not use a second account you may have on the Microsoft Exchange Server. The other calendar must be on a computer with completely different Exchange or Microsoft Windows NT logon. Set the Subject of the appointment to test recur. Right-click the Calendar folder, and then click Properties. Click the Permissions tab, and give yourself Reviewer permissions.  On your computer, run the following Visual Basic or Visual Basic for Applications automation code after setting a reference to the Microsoft Outlook 9.0 Object Library: Sub TestRecur Dim Recip As Outlook.Recipient Dim fldr As Outlook.MAPIFolder Dim CalItems As Outlook.Items Dim ResItems As Outlook.Items Dim Appt As Outlook.AppointmentItem Set ol = New Outlook.Application Set olns = ol.GetNamespace("MAPI") ' Change "emailname" to the other person's e-mail name. Set Recip = olns.CreateRecipient("emailname") Set fldr = olns.GetSharedDefaultFolder(Recip, olFolderCalendar) Set CalItems = fldr.Items CalItems.Sort "[Start]" CalItems.IncludeRecurrences = True Set ResItems = CalItems.Restrict("[Subject] = 'test recur'") For Each Appt In ResItems Debug.Print Appt.Start Next End Sub  Display the Immediate Window in the Visual Basic editor.</li></ol>

To have the above code return the correct start times for recurring appointments, change the following line of code

Dim Appt As Outlook.AppointmentItem

to

Dim Appt As Object so that the Appt variable is late-bound.

NOTE: You may also experience the problem when you refer to the properties of the parent series (such as AllDayEvent) rather than to the properties of each occurrence (Subject, Start, End).

In this situation and if you need to refer to parent series properties, do the following: After you access the occurrence properties, set a separate early-bound object variable to the late-bound object in the code sample above. Refer to series properties from the second early-bound object variable.
