OL98: Incorrect Start Dates for Shared Recurring Appointments

ID: Q187933

The information in this article applies to:

Microsoft Outlook 98

SYMPTOMS

You programmatically retrieve recurring appointments from someone else's calendar using Microsoft Visual Basic for Applications or Visual Basic Scripting Edition (VBScript), and the start dates for all of the recurring appointments are the same.

CAUSE

The other person did not give you full access to their shared folder.

WORKAROUND

Use one of the following workarounds:

Make sure you are given full permissions to the other person's shared folder.

Instead of using the Restrict method once to retrieve appointments for a specified date range, use multiple Restrict methods to retrieve the appointments one day at a time. This way each time you use the Restrict method, you inherently know the start date of the appointments.

Use the RecurrencePattern of the recurring appointment to manually calculate the start dates of the recurring appointments. This is not a trivial programming task.

IMPORTANT: If you use the updated files from the patch above, you must use early binding in order for the Restrict method to work correctly. For more information on early vs. late binding, please see the following article in the Microsoft Knowledge Base:

Q182642 OL98: (CW) How to Open Someone Else's Calendar or Other Folder

Steps to Reproduce the Problem

IMPORTANT: This code will reproduce the symptoms in the SYMPTOMS section of this article. The code does NOT create a solution.

Create a new recurring appointment in someone else's calendar. Do not use a second account on the Exchange server that you may have. The other calendar must be on a computer with completely different Microsoft Exchange or Microsoft Windows NT logons.

Set the Subject of the appointment to "test recur" (without quotation marks).

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 Outlook 98 Type Library:


      Sub TestRecur()
         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.
