What if that smtp server is not an exchange one? For example a linux postfix smtp server. Send as behalf permission is nothing to do with such a platform :)

Great question! The server does not have to be a Microsoft Exchange Server. Any SMTP server will work providing you can grant the \RTCComponentService account to relay e-mail on behalf of any enterprise user. The SMTP server would have to be able to a credential mechanism that would recognize the RTCComponentService account and allow it to relay. If that isn't an option then you might need to allow the IP address of the server Web Scheduler is running on to relay mail on behalf of all users on your SMTP server.

Hello, thanks a lot for your article

I have the same issue explained here http://social.microsoft.com/Forums/en-US/ucconferencingscheduling/thread/4fd75f78-2b7e-4a91-abfe-378aaf7a7f11

When I try to send invitations via email using OCS Web Scheduler to external users i got the message updated meeting invitations could not be sent to one or more invitees

What do I have to do in order to enable such invitations? I already gave RTCComponentService account 'Send as' permission for every domain user. Also applied latest hotfix to Web Scheduler
Thanks a lot
