Outputting from Access to Outlook Shared Calendar

The following code puts Job details into MY outlook calendar (and obviously into the Calendar of any users who create the record).

What I need is for the Calendar entry to go into my colleague Dan's shared calendar, regardless who creates the entry.

We are using Access 2010, Outlook 2010 and Exchange server 2003.

Hope you can help.
