Keep getting invites to a calendar we are not a part of (set up as Exchange mailbox)

Question

Hello,
I am hoping someone here can shed some light on an irritating problem that we are having with Exchange.
We were asked to setup a mailbox for a group, essentially just to give them a calendar.
The calendar was created successfully, but now 3 of the systems people get invitations every time someone sends out a calendar invite.  I have added the calendar to my shared calendars and looked at the permissions.  We are not on there, but we
are still getting invites.  I was asked to remove someone from the calendar, but they are also getting invites even though they are not even a part of the company anymore.  I went into their account in Exchange and hid them, and they are still listed
on the invite.  Where do we look to figure out how we are getting added to these e-mails.  I don't get it.  We are not listed anywhere in the permissions, but we still get constant invites.
Thanks,

Answer 1

You would not necessarily need permissions to a calendar to receive invitations.
Sometimes this happens when delegates are set to receive meeting invitations. In this case, I don't see why the systems people would have been added as recipients but that would be one thing to check.
