Revoked Change calendar access for a user, but they can still see it?

[Ashley]

Have removed Change calendar role, but the user can still see the calendar.  Why?

[James Ainsworth]

The Change calendar is displayed to users that have the right to view changes.  The Change Calendar role simply has two rights associated with it - View changes, and View releases.  If a user can still see the change calendar this would suggest that they have other roles associated with them that allow them to view changes and releases.  

Hope this helps.
