No. I had one attendee confirmed and then I added a person on my Microsoft
Exchange server and the confirmed attendee received a cancellation notice.
This has happened several times before and the company that i was visiting
had had the same problem but had found a fix.
It is a real hardship to set up a big meeting and send an update adding
maybe an address and some of the attendees get this cancellation notice! I
would appreciate any help you can give!
