Most invitations to a web conference arrive through email. This is to say that in most corporate environments invites to web conferences are part of an Exchange meeting invite. It appears as a web link inside the meeting invite, as shown in Figure 23.9.
Clicking the web link results in the default web browser launching. If pop-up blockers are turned on, the Lync Server warns the user. He can opt to disable the pop-up blocker for this site and refresh, or he can click a link to Join with Pop-up Blocker Turned On, although that might interfere with screen sharing. It is recommended to disable the pop-up blocker and refresh the connection.
