文档说:

表示响应中可用性视图中的时隙持续时间.默认为 30 分钟，最小值为 5，最大值为 1440.可选.

Represents the duration of a time slot in an availabilityView in the response. The default is 30 minutes, minimum is 5, maximum is 1440. Optional.

这表示availabilityView 中的时隙大小.看一个例子可能会有所帮助.

What this signifies are the size of a time slot in the availabilityView. It's probably helpful to look at an example.

这是来自文档的示例请求:

Here's the sample request from the doc:

{        
    "schedules": ["adelev@contoso.onmicrosoft.com", "meganb@contoso.onmicrosoft.com"],
    "startTime": {
        "dateTime": "2019-03-15T09:00:00",
        "timeZone": "Pacific Standard Time"
    },
    "endTime": {
        "dateTime": "2019-03-15T18:00:00",
        "timeZone": "Pacific Standard Time"
    },
    "availabilityViewInterval": 60
}

availabilityViewInterval 设置为 60，这意味着返回的 availabilityView 中的每个数字代表 60 分钟的时间块.示例响应显示了 Megan 的值 200220010.0 = 空闲，1 = 暂定，2 = 忙碌，我们可以将其解码为:

With availabilityViewInterval set to 60, that means each numeral in the returned availabilityView represents a 60 minute chunk of time. The sample response shows the value 200220010 for Megan. With 0 = free, 1 = tentative, and 2 = busy, we can decode this as:

• 上午 9 点 - 上午 10 点忙
• 上午 10 点 - 上午 11 点免费
• 上午 11 点至下午 12 点免费
• 12PM - 1PM 忙
• 下午 1 点 - 下午 2 点忙
• 下午 2 点 - 下午 3 点免费
• 下午 3 点 - 下午 4 点免费
• 下午 4 点 - 下午 5 点(暂定)
• 下午 5 点 - 下午 6 点免费

如果您在 availabilityViewInterval 设置为 30 的情况下执行相同的请求，您将返回 220000222200001100 的 availabilityView 值，每个数字代表一段 30 分钟的时间.

If you did this same request with availabilityViewInterval set to 30, you'd get back an availabilityView value of 220000222200001100, each digit representing a 30 minute chunk of time.
