Hi Blake,

To do that you will need to catch the exception that is thrown, so instead of using TryStart or TryExtend you need to use Start and Extend methods.

You can find below example code for start, but the extend should be similar.
var conflictResources = new List<Guid>();

try
{
booking = this.bookingManager.Start(Engine, booking, false);
}
catch (Exception e)
{
if (e is ResourceManagerTraceDataException exception)
{
var errorData = exception.TraceData.ErrorData.Cast<ResourceManagerErrorData>();

foreach (var error in errorData)
{
if (error.ErrorReason == ResourceManagerErrorData.Reason.ReservationUpdateCausedReservationsToGoToQuarantine)
{
foreach (var item in error.MustBeMovedToQuarantine.SelectMany(x => x.QuarantinedUsages))
{
conflictResources.Add(item.QuarantinedResourceUsage.GUID);
}
}
}
}
}

foreach (var item in conflictResources)
{
engine.GenerateInformation($"Resource in conflict: {item}");
}
