Hi Andrei,

Further to an older post, you mentioned:

When you select an email, the SelectionChange event occurs on the Explorer object representing the Outlook Explorer window in which you select the email. In add-in Express, this email is mapped to the ExplorerSelectionChange event of the Outlook Events component; you need to put it onto the add-in module.

Starting from Outlook 2010, you can manipulate the selection programmatically, see Explorer.AddToSelection(), Explorer.RemoveFromSelection() and Explorer.ClearSelection() methods.

See also http://msdn.microsoft.com/en-us/library/office/ff868732%28v=office.15%29.aspx.


I dont have "Explorer.AddToSelection(), Explorer.RemoveFromSelection() and Explorer.ClearSelection() methods. " availble to me, my addin is outlook 2007 onwards.

Can this be achieved another way?

Regards,

Tom

Hello Tom,

In Outlook 2007 there's no way to use these methods. If your add-in gets loaded in Outlook 2010 and above, you can can these methods using late binding, see System.type.InvokeMeber on MSDN.

Hi Andrei,

Thanks for that, I suppose what I am trying to achieve is which reply, replyall or forward button has been selected ie from Explorer or Inspector.

Is it possible to know?

Regards,

Tom

You can intercept the corresponding Ribbon commands; the Explorer/Inspector where the button is clicked is available using control.Context. See also sections Intercepting Built-in Ribbon Controls and Determining a Ribbon Control's Context in the manual.

Hi Andrei,

I have decided to try (Depending on which is active Explorer or Inspector, I can access the selected email that way.)

Would this be a correct method: 

#Region "Get Selected Mail Item"
    Public Function GetSelectedMailItem() As Outlook.MailItem

        Dim email As Outlook.MailItem = Nothing
        Dim ActiveExplorer As Outlook.Explorer = Nothing
        Dim currentItem As Object = Nothing

        Dim ActiveInspector As Outlook._Inspector = Nothing
        Dim olItem As Object = Nothing


        ActiveInspector = Solution_Outlook.AddinModule.Instance.OutlookHost().ActiveInspector

        If Not ActiveInspector Is Nothing Then

            olItem = ActiveInspector.CurrentItem

            Try
                If TypeOf (olItem) Is Outlook.MailItem Then

                    email = CType(ActiveInspector.CurrentItem, Outlook.MailItem)
                    Return email
                End If
            Finally
                Marshal.ReleaseComObject(email)
            End Try

        Else

            Dim currentExplorer As Outlook._Explorer = DirectCast(AddinModule.Instance.OutlookApp.ActiveExplorer, Outlook.Explorer)

            If currentExplorer IsNot Nothing Then
                Dim selection As Outlook.Selection = currentExplorer.Selection
                Try
                    If selection.Count > 0 Then
                        Dim selectedItem As Outlook.MailItem = TryCast(selection.Item(1), Outlook.MailItem)
                        If selectedItem IsNot Nothing Then
                            Return selectedItem
                        End If
                    End If
                Finally
                    Marshal.ReleaseComObject(selection)
                End Try
            End If
        End If

        Return Nothing
    End Function
#End Region


I dont think its quite right.

Regrds,

Tom

Tom,

1. Inspector-related

a) Marshal.ReleaseComObject(email) release the MailItem this method returns. This means the caller won;t be able to use it.

b)You need to release oItem if it contains any other Outlook type: TaskItem, ContactItem, etc.

2. Explorer-related

a)
Dim currentExplorer As Outlook._Explorer = DirectCast(AddinModule.Instance.OutlookApp.ActiveExplorer, Outlook.Explorer)

This will fail if there's no active explorer. Just remove the DirectCast to avoid this issue.

b)You need to release selection.Item(1) if it contains any other Outlook type: TaskItem, ContactItem, etc.

c)
Dim selection As Outlook.Selection = currentExplorer.Selection

This will fail when are are in certain folders, e.g. RSS Feeds (depends on the Outlook version used). You need to wrap currentExplorer.Selection in a try/catch block and check if the result is not Nothing.
