我正在尝试使用exchangelib从与特定主题开头\匹配的帐户中检索消息。这必须包括来自所有文件夹的消息,而不仅仅是“收件箱”文件夹。我在这里遇到了几个类似的问题
How can I get the latest emails from all folders with exchangelib?
这导致我使用FolderCollection。但是,我不清楚如何创建所有文件夹的列表并将其传递给'folders'参数。
目前我尝试了以下方法:
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')
我似乎在这里犯了一个愚蠢的错误,但无法绕过它。
有人可以让我知道实现此用例的最佳方法吗?

我看到的错误是

答案 0 :(得分:0)
问题是您的FolderCollection包含多个共享文件夹。 EWS不允许一次查询多个共享文件夹。如果您不需要搜索共享文件夹,则必须从搜索中排除它们,或者一次搜索一个共享文件夹。
