Question

Create Exchange Calendar Appointments with MAPI

Asked by: MDauphinais1

I am trying to create a VBScript that will create calendar appointments on calendars for which I have been identified as a delegate. I have the code attached working fine for my own calendar, but I can't figure out how to specify another user's calendar, while still using my login credentials? This script is meant to be run on a web server or application server without Outlook so it has to use CDO/MAPI only and cannot have any user prompts for login info.

I already know that I will have to run the file as the user with the rights on the other calendars because the password parameter is ignored in Win32 systems so that doesn't work. And if I specify a specific profile/server to use it causes a login prompt to appear.

Dim objCalendar, objAppointments, objAppt, objFolder, strUserName, strPassword
Dim blAllDay, blreminder, Status, olBusy
 
Set objCalendar = CreateObject("MAPI.Session")
objCalendar.Logon "myexchangealias", "", False, True, 0, True
 
olBusy = 2
blAllDay = False
blreminder = True
Status = "busy"   
 
        Set objFolder = _
          objCalendar.GetDefaultFolder(CdoDefaultFolderCalendar)
        If Not objFolder Is Nothing Then
       Set objAppointments = objFolder.Messages
       Set objAppt = objAppointments.Add
            If Not objAppt Is Nothing Then
                With objAppt
                    .Subject = "test55"
                    .Location = "the place"
                    .StartTime = #9/11/2009 7:00 PM#
                    .EndTime = #9/11/2009 8:00 PM#
                    .Text = "Test event."
                    .AllDayEvent = False
                    .BusyStatus = olBusy
                    .ReminderSet = True
                    If blAllDay = True Then
                    .AllDayEvent = True
                    End If
                    If blreminder = True Then
                    .ReminderSet = True
                    Else
                    .ReminderSet = False
                    End If
                    If Status = "busy" Then
                    .BusyStatus = olBusy
                    End If
                    If Status = "ooo" Then
                    .BusyStatus = olOutOfOffice
                    End If
                    If Status = "free" Then
                    .BusyStatus = olFree
                    End If
                    .Update
                End With
            End If
        End If
 
    Set objFolder = Nothing
    Set objAppointments = Nothing
    Set objAppt = Nothing
 
objCalendar.Logoff
set objCalendar=Nothing

<pre id="codeSnippet408292" class="prettyprint">objCalendar.GetDefaultFolder(CdoDefaultFolderCalendar)
is part of the problem.  It gets the Calendar folder for your mailbox only.

I believe you will need to open the other persons mailbox and iterate through the toplevel folders to find the calendar folder.
But thats not something I have tried. Most of my needs have been with PublicFolders.

Hi,

I don't use CDO any more but I use Redemption RDO regularly - as it has a much better feature set. I'm not sure whether getshareddefaultfolder is a CDO method as well as an RDO method.

The code to get the shared Calendar of another user using RDO would be:

set Session =              CreateObject("Redemption.RDOSession")
            Session.MAPIOBJECT = Application.Session.MAPIOBJECT
            set Folder = Session.GetSharedDefaultFolder("dmitry", olFolderCalendar)

The element showing "dmitry" is Name Or Address Or Object              - can be a string representing the Exchange mailbox name or address or              an RDOAddressEntry or an             RDORecipient object.

My exerience of using this tells me that you need to have permissions to see items in that folder to do what you are trying to do.

DavidT543, thank you. That worked perfectly. I've never heard of RDO before but that's pretty nice. I'm a little disappointed that CDO doesn't support this though. Hopefully my server admins won't have an issue with installing redemption on a server that will run this VBScript file.

 

by: MDauphinais1Posted on 2009-09-14 at 15:30:42ID: 25329918

DavidT543, would you know how to update a specific calendar appointment by it's GlobalAppointmentID (or entryID - I think that's the same thing) using this RDO? I can't figure it out...

Disregard, I figured it out.
