The account you are going to use will need to be given a mailbox, so that you can grant permissions to it in Outlook. Once you have created the account, you can use something like setperm to change the permissions on the mailboxes to allow this account access to the calendar folder.

How do I give one particular user - not a domain administrator just a normal user account, access to all users mailboxes, especially their calendars to insert and delete appointments. This user does not have a mailbox. This account is used by an HR application to update their calendars with leave information.
