I tried following approach and it worked.
rename .twb file to .xml
(if your tableau file is twbx then rename this file to .zip . get .twb file from this zip file. )
Open in notepad
search for following text:

At outlook go to file –> options –> Add-ins –> Manage – COM Add-ins GO –> At add-ins available uncheck skype related items.
