I have a User Profile synchronization service that seems to be working well. The User Profile pages of new staff members are populating correctly, including changed data from AD and our BDC. Users who have left the organization and no longer have active AD accounts no longer have User Profile pages with "User not found". Great. I assume my synchronization is working.
However, when I look at my hidden User Information List I still see users who have left. The UIL is updating correctly for active and new users. It seems just removes aren't working. Any idea what is going on here?
