Update access is denied to current user

I am using GroupWise 7, and want to update an appointment using the 
GroupWise COM objects.

I am finding that when I try to sent a property - such as the appointment 
date - I am getting the error:

Update access is denied to current user.

However the appointment is in the local user's calendar and they can go into 
GroupWise and change details of the appointment through the normal client.

Why am I getting the access denied message? 

Here is some more information

I am creating a groupwise session

Set gw = CreateObject("NovellGroupWareSession")

and logging in with

gw.Login

To login as the current user. If you access the gw.RootAccount.Owner it will 
show you the current user, who you are logged in as.

Now you can sent emails, create appointments etc as this user etc

My problem is that I can't update existing appointments - what else do I 
need to do to achieve this?

Example code:

Dim gwApp As GroupwareTypeLibrary.Appointment7
Dim m As GroupwareTypeLibrary.Message3
Dim ml As GroupwareTypeLibrary.MessageList
Dim searchStr As String

   searchStr = "(START_DATE >= TODAY -5)"
   Set ml= gGw.RootAccount.Calendar.Messages.Find(searchStr)

    For Each m In ml
        If m.MessageID = msgId Then
            If m.className = "GW.MESSAGE.APPOINTMENT" Then
                Set gwApp = m
            End If
        End If
    Next m

   if not gwApp is nothing then
       gwApp.startDate = CDate(strDateTime)

At this point I get the "Update access is denied to current user"

Thanks for any help anyone can give
