I have several conference rooms with resource accounts and shared calendars for users to book rooms for meetings. Recently, all these calendars started declining entire recurring meetings if there is a single conflict. Example, a user adds Conference Room A as the location for a recurring meeting every Monday at 9:30 am. There is already a single meeting scheduled for that room in two weeks at that time. Instead of declining just that single day, it declines ALL and gives a single day as the reason. I'm just not seeing any settings for this.
