For the first, I'm bit surprise, because when you are using Webex productivity tool, a Plug-In is installed on all MS Office application include MOC, it means you can start an ad-hoc webconference from any of this application, as I understood, it's not possible the the CUPC except if you have webex onsite (you means Webex Node for MCS) ? Please can you confirm ?
Regarding my second question, to be more precise:
When you want to add a new "budy/contact" in the MOC, you fill in the name in the "search" and MOC make a lookup either in the Corporate Directory and in the Private contact, see my the exemple, in the image.
I made a example: I'm looking for Mr. Hauert (I have this contact in my Outlook contact list), when I lunch the search, MOC is searching in the corporate directory AND in my Outlook Private Contact.
What the advantage: You have one data base where you have all your private contact information with all details (Phone Number, Email, Adresses, etc..) and you need only to maintain one DB.
If Personnal Communicator can not do that natively, I think it's a Missing feature, can you confirm ?
