NOTE: One day is interpreted as being 24 hours after a specific user profile was most recently accessed. This problem occurs because of an error in the User Profile Service. The Group Policy setting uses the time at which the profile was created rather than the time at which the profile was last used as the basis for determining when to delete the profile. Therefore, even if the user profile is still being used, it is deleted after the specified number of days have elapsed since the time at which created the profile.
