使用exchangelib過濾帳戶中所有文件夾中的消息

Question

我正在嘗試使用exchangelib從與特定主題匹配\\開始的帳戶中檢索消息。 這必須包括來自所有文件夾的消息，而不僅僅是“收件箱”文件夾。 我在這里遇到了幾個類似的問題

如何使用exchangelib從所有文件夾中獲取最新電子郵件？

這導致我使用FolderCollection。 但是，我不清楚如何創建所有文件夾的列表並將其傳遞給'folders'參數。

目前，我嘗試了以下方法：

conf = Configuration(server=ex_srv, credentials=cred)
acct = Account(primary_smtp_address=email, 
                            config=conf, 
                            autodiscover=False, 
                            credentials=cred, 
                            access_type=IMPERSONATION
                        )

from exchangelib.folders import Messages, FolderCollection
all_folder_list = acct.folders[Messages]
all_folder_collection = FolderCollection(account=acct, folders=all_folder_list)

all_folder_collection.filter(subject__startswith='test')

我似乎在這里犯了一個愚蠢的錯誤，但無法解決它。

有人可以讓我知道實現此用例的最佳方法嗎？

我看到的錯誤是

問題是您的FolderCollection包含多個共享文件夾。 EWS不允許一次查詢多個共享文件夾。 如果不需要搜索共享文件夾，則必須從搜索中排除它們，或者一次搜索一個共享文件夾。
