If i recall of the top of my head:
Edit or create WebApp.ini within the Enterprise Vault directory
and set "ViewMessage_Format"
values
- WEB (default). Display the item in a browser window.
- MSG. Use Outlook to display the item. (Not available on Mac clients.)
- ASK. Prompt the user for the format to use. (Not available on Mac clients.
Just remember this affects the following:
- Links in universal shortcuts
- Items that are opened in Archive Explorer
So I guess you want to add ViewMessage_Format=MSG to WebApp.ini
