Thank you for your response ToanDN. The issue is that revit is saying that I (micphillips) own an element within the architectural model, which I've never opened. My colleague is in the same room as I and notified me that he could not edit his floor plan because I owned it, within his architectural model. Also, when we go to lunch, we all lock out computers so it would not be possible that somebody used my computer to access the model. That being said, a local temp file would have been created for that file, which it has not.
