I have setup a user on exchange 2003 with two email addresses (email@example.com and firstname.lastname@example.org). We want to share this users calendar and give read permissions to everyone but create permissions to two organisers. They can then send invites out and recieve responses. However - some meeting requests need to go from email@example.com and some from firstname.lastname@example.org. In outlook the delegate user can send normal email by using the from field but I can't find a from field in the meeting request? Am I going about this the wrong way or does anyone know how to use the from functionality in a meeting request please?
