Is there a way to have a user's mailbox calendar shared and linked to an intranet portal?Jason

Depends on what is hosting the intranet portal. If you are using one of the popular portal products then they usually have pluginsto outlook.

Hi Jason, Maybe you can follow this thread to have a user’s mailbox calendar shared: Share public calendar via a web link for anonymous users http://social.technet.microsoft.com/Forums/en-US/exchange2010/thread/8156969c-8eb1-4538-bb26-9a935ed9ccd6/ If you want calendar linked to an intranet portal, maybe you can use SharePoint to achieve the goal.

Evan, Thank you for the post but I am currently running Exchange 2007. Will this solution work in my scenario? "Depends on what is hosting the intranet portal." We are just using a basica IIS server for a portal hosting at this time.Jason
