Webex Meeting: Setting up a meeting from Webex site
Setting up a meeting from uwmadison.webex.com
You can set up instant and scheduled meetings from a browser by going to uwmadison.webex.com . You can also schedule meetings from Outlook Desktop application. Using your primary email and then you will be prompted for your NetID and password.
These directions show you how to schedule a meeting through the site URL -uwmadison.webex.com using a browser. You can add alternate host and create recurring meetings. The disadvantage of scheduling a meeting through the direct URL is the directory is not tied to Webex, so you will need to input all email addresses.
