Call Outlook procedure using VBScript - vba

Question

I have a procedure in Outlook that sends all the saved messages in Drafts folder.
Below is the code:
Public Sub SendMail()
Dim olApp As Outlook.Application
Dim olNS As Outlook.NameSpace
Dim olFolder As Outlook.MAPIFolder
Dim olDraft As Outlook.MAPIFolder
Dim strfoldername As String
Dim i As Integer
Set olApp = Outlook.Application
Set olNS = olApp.GetNamespace("MAPI")
Set olFolder = olNS.GetDefaultFolder(olFolderInbox)
strfoldername = olFolder.Parent
Set olDraft = olNS.Folders(strfoldername).Folders("Drafts")
If olDraft.Items.Count <> 0 Then
For i = olDraft.Items.Count To 1 Step -1
olDraft.Items.Item(i).Send
Next
End If
End Sub
Above code works fine.
Question:
I want to use Task Scheduler to fire this procedure as a specified time.
1. Where will I put the procedure in Outlook, Module or ThisOutlookSession?
2. I am not good in vbscript so I also don't know how to code it to call the Outlook Procedure. I've done calling Excel Procedure but Outlook doesn't support .Run property.
So this doesn't work:
Dim olApp
Set olApp = CreateObject("Outlook.Application")
olApp.Run "ProcedureName"
Set olApp = Nothing
I've also read about the Session.Logon like this:
Dim olApp
Set olApp = CreateObject("Outlook.Application")
olApp.Session.Logon
olApp.ProcedureName
Set olApp = Nothing
But it throws up error saying object ProcedureName is not supported.
Hope somebody can shed some light.
SOLUTION:
Ok, I've figured out 2 work around to Avoid or get pass this pop-up.
1st one: is as KazJaw Pointed out.
Assuming you have another program (eg. Excel, VBScript) which includes sending of mail via Outlook in the procedure.
Instead of using .Send, just .Save the mail.
It will be saved in the Outlook's Draft folder.
Then using below code, send the draft which fires using Outlook Task Reminder.
Option Explicit
Private WithEvents my_reminder As Outlook.Reminders
Private Sub Application_Reminder(ByVal Item As Object)
Dim myitem As TaskItem
If Item.Class = olTask Then 'This works the same as the next line but i prefer it since it automatically provides you the different item classes.
'If TypeName(Item) = "TaskItem" Then
Set my_reminder = Outlook.Reminders
Set myitem = Item
If myitem.Subject = "Send Draft" Then
Call SendMail
End If
End If
End Sub
Private Sub my_reminder_BeforeReminderShow(Cancel As Boolean)
Cancel = True
Set my_reminder = Nothing
End Sub
Above code fires when Task Reminder shows with a subject "Send Draft".
But, we don't want it showing since the whole point is just to call the SendMail procedure.
So we added a procedure that Cancels the display of reminder which is of olTask class or TaskItem Type.
This requires that Outlook is running of course.
You can keep it running 24 hours as i did or, create a VBscript that opens it to be scheduled via Task Scheduler.
2nd one: is to use API to programatically click on Allow button when the security pop-up appears.

Here is the LINK which will help you programmatically click on the Allow button.
Of course you have to tweak it a bit.

Tried & Tested!
Assuming that you have Outlook Application always running (according to comment below your question) you can do what you need in the following steps:
add a new task in Outlook, set subject to: "run macro YourMacroName" and set time (plus cycles) when your macro should start.
go to VBA Editor, open ThisOutlookSession module and add the following code inside (plus see the comments inside the code):
Private Sub Application_Reminder(ByVal Item As Object)
If TypeName(Item) = "TaskItem" Then
Dim myItem As TaskItem
Set myItem = Item
If myItem.Subject = "run macro YourMacroName" Then
Call YourMacroName '...your macro name here
End If
End If
End Sub

Answer 2

Where will I put the procedure in Outlook, Module or ThisOutlookSession?
Neither. Paste the below code in a Text File and save it as a .VBS file. Then call this VBS file from the Task Scheduler as shown HERE
Dim olApp, olNS, olFolder, olDraft, strfoldername, i
Set olApp = GetObject(, "Outlook.Application")
Set olNS = olApp.GetNamespace("MAPI")
Set olFolder = olNS.GetDefaultFolder(6)
strfoldername = olFolder.Parent
Set olDraft = olNS.Folders(strfoldername).Folders("Drafts")
If olDraft.Items.Count <> 0 Then
For i = olDraft.Items.Count To 1 Step -1
olDraft.Items.Item(i).Send
Next
End If

Answer 3

If you are using Outlook 2007 or newer I have found you can easily eliminate the security pop up you mentioned above when running your script by doing the following:
In Outlook 2007 Trust Center, go to Macro Security - Select "No security Check for macros"
In Outlook 2007 Trust Center, go to Programatic Access - Select "Never warn me abous suspicious activity.
Of course that technically leaves you open to the remote possibility for someone to email you some malicious email script or something of that nature I assume. I trust my company has that managed though and this works for me. I can use VBS scripts in Outlook, Access, Excel to send emails with no security pop up.
Another Option:
If you don't want to do that, another option that has worked well for me prior to this is here:

Basically a dll redirect that does not include the popup. It leaves your other default security in place and you write \ call your VBA for it and send mail without the secutity pop-ups.
