Can anyone help me please?
I use the calendar to send out training invites for in-house courses we run
and receive hundreds of responses.
I have noticed that when I mark responses as read they still do not update
the acceptance/decline in the meeting request. I have to manually open or
preview pane each response for the calendar to update.

Is there an easier way??
Shouldnt it automatically update the calendar once the response is received
- whether it has been read or not?????

I dont see why the calendar does not automatically update if you mark the
item as read!!
Its sooo time consuming.
