Symptoms
We need to define an user who needs to be able to manage "Out of office" status for other users. In K2 Portal SharePoint 2010 site, a normal user gets "Access denied" if he tries to access the page about "out of office" users.
What are the permissions required for an user to enable him to manage "out of office" status of other users ?
