I wanted to set up a meeting. So I invited some works. The meeting was going to be from 4:00 PM to 5:00 PM. One person I invited modified his working time from 7:00 AM to 3:00 PM. When I select plan a meeting and invite him, it tells me he is "free". Actually he stopped working at 3:00 PM, but it doesn't tell me that. Any help>>
