How can I tell who am a delegate for in Outlook 2010?

[twixthecat]

A user, not on the invite list, is receiving calendar invitations for large team meetings being sent out. This user is in a remote office and just wants to stop receiving these unwanted invite notices.

It seems like the user may have been set as a delegate for one of the invitees in error. Without having to check with everyone on the (long) invite list, is there a way the user can check if they have been set as a delegate for someone?

Thanks
