organization browser inside my site in sharepoint not working and it displays "WebPage Not Found" what may be the reason?
Has this already functioned?
If not, you'll need to verify that User Profile Synchronization service is active in Central Administration. Once its started go to your service applications and select User Profile Service application and click Manage on the ribbon. Once you do that under the profile synchronization connections create a new connection. Wait until the profile synchronization is over and then go to the organization browser and you will see the the results.
