Delegates appear as invited when they were not
 

I hope someone can help me. When I send a meeting invitation to a group of
executives naturally their delegates receive a copy of it. The problem is
that if the delegate accepts the invitation, the meeting invite then shows
their name as being invited to the meeting. I never invited them! My boss
sometimes sees theis and asks why I've invited them. How can I prevent them
from showing up as invited.

Please understand this is not a case of them showing as accepting for X
person...the meeting is actually showing them as invited and accepted.

Please help.
