vba – How can I supress the Outlook warning while sending mail using macro in excel

Posted by: admin March 9, 2020 Leave a comment

Questions:

I am trying to send an email using macro in excel.

But when I run this code my mail client i.e. MS Outlook shows a pop up warning similar to
Someone is tying to send mail on behalf of you. select yes or no

Is there any way using to suppress that warning so the email should be sent without any problem?

How to&Answers:

The best way I know is to create an outlook application item, create the message, display the message and use sendkeys to send the message (equivelent of typing alt s).

The drawback is that the sendkeys method can be a bit buggy. To make it more robust I get the inspector for the mail item i.e. the window it is in and activate it immediately prior to the call to sendkeys. The code is shown below:

Dim olApp As outlook.Application
Dim objNS As Outlook.Namespace
Dim objMail As Outlook.MailItem
Dim objSentItems As Outlook.MAPIFolder
Dim myInspector As Outlook.Inspector

'Check whether outlook is open, if it is use get object, if not use create object
On Error Resume Next
Set olApp = GetObject(, "Outlook.Application")
On Error GoTo 0
If olApp Is Nothing Then
    Set olApp = CreateObject("Outlook.Application")
End If

Set objNS = olApp.GetNamespace("MAPI")
objNS.Logon

'Prepare the mail object    
Set objMail = olApp.CreateItem(olMailItem)

With objMail
.To = <insert recipients name as string>
.Subject = <insert subject as string>
.Body = <insert message as string>
.Display   
End With

'Give outlook some time to display the message    
Application.Wait (Now + TimeValue("0:00:05"))

'Get a reference the inspector obj (the window the mail item is displayed in)
Set myInspector = objMail.GetInspector

'Activate the window that the mail item is in and use sendkeys to send the message
myInspector.Activate
SendKeys "%s", True

I normally then have code to check that the number of items in the sent folder has increased and if not I get the application wait again and repeat the last 2 lines of code and recheck that the number of messages in the sent folder has increased. The code does this upto 5 times. After the 5th time a message box comes up warning that the message may not have been sent.

I have never found this method to fail in sending a message from excel though I once saw the warning message when our system was particularly slow, on investigation it turned out that the message had been sent.

Answer:

You need use a Redemption DLL to disable this warning…

Answer:

the window is popping up to begin with because the macro is not signed by a Trusted Publisher. This list in your Outlook settings. You must sign the macro and input the signer into your trusted publishers list. Or allow unsigned macros globally.

I found the code below somewhere on the internet a couple of years ago. It automatically answers ‘Yes’ for you.

Private Declare Function RegisterWindowMessage _

Answer:

A few options:

  1. Use up-to-date antivirus software (Outlook will not display a prompt then)
  2. Extended MAPI (C++ or Delphi only, does not apply in case of VB script or .Net languages). You can however use a wrapper like Redemption that uses Extended MAPI but is accessible from any language including VBS.
  3. A product like ClickYes.

See http://www.outlookcode.com/article.aspx?id=52 for a discussion and a list of available options.

Answer:

This Outlook VBA will load an excel file with emails stored as records and send all of them.

Option Explicit

 Private Const xlUp As Long = -4162

Sub SendEmailsFromExcel()

    Dim xlApp As Object

    Dim isEmailTo As String    ' Col A
    Dim isSubject As String    ' Col B
    Dim isMessage As String    ' Col C

    Dim i As Integer
    Dim objMsg As MailItem
    Set objMsg = Application.CreateItem(olMailItem)

    Dim emailsMatrix As Variant

    Dim objWB As Object
    Dim objWs As Object
    Dim FileStr As String

    FileStr = "C:\Users\...\Documents\EmailsInExcel.xlsx"

    Set xlApp = CreateObject("excel.application")

    With xlApp
        .EnableEvents = False
        .DisplayAlerts = False
    End With

    Set objWB = xlApp.Workbooks.Open(FileStr)
    Set objWs = objWB.Sheets(1)

    ' Matrix load:  A - Email Address, B - Subject, C - Body
    emailsMatrix = objWs.Range("A1:C" & xlApp.Cells(objWs.Rows.Count, "A").End(xlUp).Row)

    objWB.Close

    Set objWB = Nothing
    xlApp.Quit
    Set xlApp = Nothing

'   Done getting Excel emails file.

    For i = 1 To UBound(emailsMatrix)
        isEmailTo = emailsMatrix(i, 1)
        isSubject = emailsMatrix(i, 2)
        isMessage = emailsMatrix(i, 3)


        objMsg.Recipients.Add isEmailTo
        objMsg.Subject = isSubject
        objMsg.Body = isMessage
        objMsg.Send
    Next i

End Sub
