Hi everyone,
An Add-in i built creates meetings and sends each to many recipients.
After the meeting was sent i need to sent a meeting cancellation to several
of the recipients and an update to other recipients.

Illustration:
(meeting creation)
1. create appointment
2. add recipients
3. send meeting

(here is where i need your help)
Now after the meeting was sent i need to send a cancellation to some of the
recipients list and an update to the rest of the list.

I'm using Demitry's redemption to handle the outlook object model.

I would realy appreciate any help.
Code samples are prefered.

Thanks in advance,
Asaf
