Assigning Sensitivity to an outlook email

[RZoig]

Hello

I've created (after some search) a set of VBA code that use Outlook (this is mandatory) to send mails according to a list in Excel
Everything is working fine except one (critical) thing.

My organization as set 'Internal use' as a default setting for every new emails in Microsoft Outlook.
I've inserted a line to change Sensitivity to 'normal'
Nothing changes!
Emails keep being sent with 'internal' sensitivity and can't be read outside my organization!

This is part of the code:

' create email​

Set objEMAIL = ObjOutlook.CreateItem(olMailItem)​

With objEMAIL​

.Display​

'who​

.SendUsingAccount = ObjOutlook.Session.Accounts(1)​

.SentOnBehalfOfName = "xxxx@xxx.xx"​

' define sensitivity (NOT WORKING)​

.Sensitivity = olNormal​

'Subjet​

.Subject = "Test"​

'Body​

.HTMLBody = "hello.<br/><br/><b/>Test "​

' Email​

.To = Email​

'Check​

If Anexo <> "" Then​

.Attachments.Add Anx​

'Sent​

.Send​

The macro works smoothly, emails are being sent but sensitivity doesn't change.

This line:
.Sensitivity = olNormal
Should it be different in order to emails are sent with Outlook 'Public' sensitivity??

Thank You!
