Launch Outlook from form in Access

I'm trying to launch Outlook from a form within Access, can can't get the VBA code right.
Also, I'm trying to open the calendar and tasks in new windows.

Here is some sample code I was invoking from a button control on an Access form, but I'm getting an "could not complete the operation. One or more parameter values are not valid" error.

Any help you could provide would be greatly appreciated.

Set myOlApp = CreateObject("Outlook.Application")
Set myNameSpace = myOlApp.GetNameSpace("MAPI")
Set myFolder = myNameSpace.GetDefaultFolder(olFolderInbox)
myFolder.DisplayStart Free Trial
