Hyperlinks in a published presentation do not navigate to the URL specified.
The Macromedia Breeze Plug-in for PowerPoint currently only supports hyperlinks that were created in Microsoft PowerPoint.
When adding hyperlinks to a presentation, use the Insert > Hyperlink command to associate text with a hyperlink. By using this function in PowerPoint, the Macromedia Breeze Plug-in for PowerPoint will convert the hyperlinks correctly during publishing.
For more details, please refer to Email address is not clickable after publishing a presentation (TechNote tn_18695).
