Answer 1

If you want specifically want an outlook message and you want more options on what to send (body text, attachments, BCC, etc.):

Dim Outl As Object
Outl = CreateObject("Outlook.Application")
If Outl IsNot Nothing Then
    Dim omsg As Object
    omsg = Outl.CreateItem(0) '=Outlook.OlItemType.olMailItem'
    'set message properties here...'
    omsg.Display(True) 'will display message to user
End If

Answer 2

Dim Outl As Object
Outl = CreateObject("Outlook.Application")
If Outl IsNot Nothing Then
    Dim omsg As Object
    omsg = Outl.CreateItem(0)
    omsg.To = "yusuf@hotmail.com"
    omsg.bcc = "yusuf@gmail.com"
    omsg.subject = "Hello"
    omsg.body = "godmorning"
    omsg.Attachments.Add("c:\HP\opcserver.txt")
    'set message properties here...'
    omsg.Display(True) 'will display message to user

Imports System.Diagnostics

Process.Start(String.Format("mailto:{0}", address))

' set all possible parameters: '

Process.Start(String.Format("mailto:{0}?subject={1}&cc={2}&bcc={3}&body={4}", address, subject, cc, bcc, body))

' also escape spaces: '

Process.Start(String.Format("mailto:{0}?subject=\"{1}\"&cc={2}&bcc={3}&body=\"{4}\"", address, subject, cc, bcc, body))

Use next to include new line breaks:

body = body.Replace(Environment.NewLine ,"%0A")

will open default email client with new message composition dialog.

If Outlook is set as default client, it will be opened.

Anyway, never open explicitly non-default client (email, browser, etc) - that breaks clients' will and makes them hate you.
