When a user is invited to a meeting, the user receives a meeting invitation through Office Outlook. In the meeting invitation, there is a link for users to download and install the Office Live Meeting 2007 client. If you have configured the server to support meetings for both internal and external users, there is both an internal link and an external link for users to download and install the meeting client. You can customize the internal client download link. The external client download URL is hosted by Microsoft.

Meeting invitations also include a link to a support page. By default, a support page that contains generic content is hosted by the server that is running the Office Communications Server Web Components, but you can host your own support page on the server that is running the Web Components or on your own Web server.
