NullReferenceException at Microsoft.Office.Server.Administration.UserProfileApplicationProxy.get_ApplicationProperties()

You get the exception below when browsing to your SharePoint site. In my case this happened on a brand new site that I just created.

Server Error in ‘/’ Application.

Object reference not set to an instance of an object.

Stack Trace:

Searching for this on Google will turn up quite a number of hits. Some people reported that deleting and recreating the User Profile Service Application (UPSA) fixed the issue. However, this isn’t always an option – it certainly wasn’t in my case.

In my case the problem was because the app pool account of the web application did not have permission to the UPSA. I fixed this by:

  • Go to Central Admin, then Manage service applications
  • Click on the row (not the link) of the UPSA to highlight it
  • From the ribbon, click Permissions then grant the app pool account of the web application Full Control (the only option)
  • Do not use the Administrators button on the ribbon. Adding the app pool account to the Administrators list did not fix the issue in my case.
