Using Outlook 2000 I have client who sends meeting invitations to various
members of the Global Address List and her contacts folder. If the organiser
then changes the meeting and sends an update, some members do not receive the
update and the organiser gets the following message: "This message will not
be sent to A and B" (where A and B are original recipients of the
invitation). Also, after sending the update,she gets another error:.
"inavlid parameters".

Does anyone have any explanation as to why this would happen? Does using
Distribution Lists affect anything? Does being a delegate cause these types
of problems? Or, is Outlook just sometimes "flakey"?

All help is greatly appreciated.
