    Dim smtpclient As New MailKit.Net.Smtp.SmtpClient  
     Dim mail As New MimeKit.MimeMessage  
     smtpclient.Connect("smtp.office365.com", 587, MailKit.Security.SecureSocketOptions.StartTls)  
     smtpclient.Authenticate("email address removed for privacy reasons", "Aprile22")  
     mail.From.Add(New MimeKit.MailboxAddress("", "email address removed for privacy reasons"))  
      For i = 0 To mailinglist.Count - 1  
     mail.Bcc.Add((New MimeKit.MailboxAddress("",mailinglist(i).ToString)))  
     Next  
     contenutomail.TextBody = ""  
     contenutomail.HtmlBody = "hello world"

Assuming your admin allowed smtp access to shared mailboxes, you add the mailbox name to user login name

Username\mailboxname

The mailbox name must be unquie. If not have admin create a unique alias.
