Answer 1

If you are using multiple POP3/SMTP accounts, set the MailItem.SendUsingAccount property to one of the accounts from the Namespace.Accounts collection.

If you are using Exchange, set the MailItem.SentOnBehalfOfName property - you must have an explicit permission to send on behalf of that user.

Answer 2

Try this

With OutMail
        .SentOnBehalfOfName = "YourEmailAccount@Email.com"
        .to = Range("AF" & ActiveCell.Row)
        .CC = "something@something.com"
        .BCC = ""
        .Subject = "New Supplier Request - Update"
        .Body = strbody
        'You can add a file like this
        '.Attachments.Add ("C:\test.txt")
        .Send   'or use .Display
    End With
