如何獲取Outlook用戶列表的空閒/忙碌狀態（以及如何獲取用戶列表）？

Question

我在MS Outlook 2010上試圖讓HR的生活更輕鬆。

鑑於用戶列表（所有用戶顯然都擁有Outlook帳戶），我希望在未來的某個日期加載其空閒/忙碌狀態。

如果我可以得到一個用戶列表，那也是有用的，但不是必需的。

一旦我處理了數據，我想以編程方式發送預約請求。

由於我在Outlook 2010中，顯然我不能使用最新服務器中提供的REST接口（據我所知）。我很想通過sql訪問這些信息，但我不認爲sql服務器允許這樣做。

我想避免VB。我可以做C＃，但寧願Python。我已安裝「win32com.client」，但無法找到獲取用戶列表或獲取給定用戶列表的空閒/忙碌時間的示例。

想了解任何建議。

Answer 1

前段時間，我編寫了一些代碼來在特定時間獲取某人的忙/閒狀態。我想你可以使用這段代碼作爲獲取你需要的起點。請享用！
