Recurring Meeting: Forward - Send this occurrence

From the calendar, go to intended date, double-click desired meeting, select
"Open this occurrence" of a recurring meeting. Select Forward from the
Actions pulldown menu, select "Send this occurrence" and OK. Type in the
name(s) you wish to send the single meeting instance to [note: it should be
a blank TO: field by default, if not, replace any existing names with the
desired single instance recipients], perform a Check Names, then select Send.

Recipient receives invites, accepts, and sends response. Acceptance
response received by Organizer. Organizer opens response (seems to be
required in order for the tracking information to get updated).

Go back to the same instance of the recurring meeting used to send the
occurrence, open meeting by selecting "Open this occurrence." Invitees name
will appear in Distribution names for that instance. Close meeting and
reopen same or other occurrence by selecting "Open the series" -- Invitees
name(s) who were intended to receive only an occurrence are listed in the
series distribution names -- UNDESIRABLE, as it makes them part of any
updates made to the recurring meeting series. However, invitee received only
the one occurrence and only the one instance is present on their calendar --
DESIRABLE. << This appears to be a bug, in my opinion, and not just a
"feature". >>

Now, a workaround to the "intended" process is to open the occurrence of the
only meeting instance you wish the invitees to attend (and not end up as part
of the series distribution), add any names in the TO: field you want to send
just the occurrence to and perform a Check Names, select Save and Close, then
select "Send updates only to added or deleted attendees" and OK.

Go back to the same instance of the recurring meeting used to send the
occurrence, open meeting by selecting "Open this occurrence." Invitees name
will appear in Distribution names for that instance. Close meeting and
reopen same or other occurrence by selecting "Open the series" -- Invitees
name(s) who were intended to receive only an occurrence are NOT listed in the
series distribution names -- DESIRABLE.

I have not been able to locate any articles or posts that detail this
behavior. Please advise.
