安装

您可以从pypi安装此软件包：

pip install exchangelib

默认安装不支持kerberos。要获得其他kerberos支持，请安装 使用额外的kerberos依赖项：

pip install exchangelib[kerberos]

要安装最新的代码，请直接从github安装：

pip install git+https://github.com/ecederstrand/exchangelib.git

exchangelib使用lxml包和pykerberos来支持kerberos身份验证。 要安装这些软件，您可能需要安装一些附加的操作系统软件包。

在ubuntu上：

apt-get install libxml2-dev libxslt1-dev

# For Kerberos support, also install these:
apt-get install libkrb5-dev build-essential libssl-dev libffi-dev python-dev

在CentOS上：

# For Kerberos support, install these:
yum install gcc python-devel krb5-devel krb5-workstation python-devel

在freebsd上，pip需要一些帮助：

pkg install libxml2 libxslt
CFLAGS=-I/usr/local/include pip install lxml

# For Kerberos support, also install these:
pkg install krb5
CFLAGS=-I/usr/local/include pip install kerberos pykerberos

对于其他操作系统，请参考python包的文档 无法安装。

Fault-tolerance# means that requests to the server do an exponential backoff and sleep for up to a certain# threshold before giving up, if the server is unavailable or responding with error messages.# This prevents automated scripts from overwhelming a failing or overloaded server, and hides# intermittent service outages that often happen in large Exchange installations.# If you want to enable the fault tolerance, create credentials as a service account instead:credentials=ServiceAccount(username='FOO\\bar',password='topsecret')# An Account is the account on the Exchange server that you want to connect to.

This cache is shared between processes and is not deleted when your program exits.# A cache entry for a domain is removed automatically if autodiscovery fails for an email in that# domain. It's possible to clear the entire cache completely if you want:fromexchangelib.autodiscoverimport_autodiscover_cache_autodiscover_cache.clear()

代理和自定义TLS验证

如果需要代理支持或自定义TLS验证，可以提供 自定义"请求"传输适配器类，如中所述 http://docs.python requests.org/en/master/user/advanced/传输适配器

下面是一个使用不同自定义根证书的示例，具体取决于 要连接到的服务器：

fromurllib.parseimporturlparseimportrequests.adaptersfromexchangelib.protocolimportBaseProtocolclassRootCAAdapter(requests.adapters.HTTPAdapter):# An HTTP adapter that uses a custom root CA certificate at a hard coded locationdefcert_verify(self,conn,url,verify,cert):cert_file={'example.com':'/path/to/example.com.crt','mail.internal':'/path/to/mail.internal.crt',}[urlparse(url).hostname]super(RootCAAdapter,self).cert_verify(conn=conn,url=url,verify=cert_file,cert=cert)# Tell exchangelib to use this adapter class instead of the defaultBaseProtocol.HTTP_ADAPTER_CLS=RootCAAdapter

下面是添加代理支持的示例：

fromexchangelibimportCredentials,Accountcredentials=Credentials('john@example.com','topsecret')account=Account('john@example.com',credentials=credentials,autodiscover=True)foriteminaccount.inbox.all().order_by('-datetime_received')[:100]:print(item.subject,item.sender,item.datetime_received)

exchangelib提供忽略tls验证的示例适配器错误。自担风险使用。

fromexchangelibimportCredentials,Accountcredentials=Credentials('john@example.com','topsecret')account=Account('john@example.com',credentials=credentials,autodiscover=True)foriteminaccount.inbox.all().order_by('-datetime_received')[:100]:print(item.subject,item.sender,item.datetime_received)

文件夹

所有已知文件夹都可用作帐户的属性，例如account.root，account.calendar， account.trash，account.inbox，account.outbox，account.sent，account.junk，account.tasks和 帐户.联系人

fromexchangelibimportCredentials,Accountcredentials=Credentials('john@example.com','topsecret')account=Account('john@example.com',credentials=credentials,autodiscover=True)foriteminaccount.inbox.all().order_by('-datetime_received')[:100]:print(item.subject,item.sender,item.datetime_received)

日期、日期时间和时区

EWS对日期时间和时区有一些特殊要求。你需要 要使用特殊的类 处理日期时。

fromexchangelibimportCredentials,Accountcredentials=Credentials('john@example.com','topsecret')account=Account('john@example.com',credentials=credentials,autodiscover=True)foriteminaccount.inbox.all().order_by('-datetime_received')[:100]:print(item.subject,item.sender,item.datetime_received)

创建、更新、删除、发送和移动

fromexchangelibimportCredentials,Accountcredentials=Credentials('john@example.com','topsecret')account=Account('john@example.com',credentials=credentials,autodiscover=True)foriteminaccount.inbox.all().order_by('-datetime_received')[:100]:print(item.subject,item.sender,item.datetime_received)

批量操作

fromexchangelibimportCredentials,Accountcredentials=Credentials('john@example.com','topsecret')account=Account('john@example.com',credentials=credentials,autodiscover=True)foriteminaccount.inbox.all().order_by('-datetime_received')[:100]:print(item.subject,item.sender,item.datetime_received)

搜索

搜索是根据django queryset api建模的，并且 支持API。就像在Django，Queryset很懒 在迭代queryset之前获取任何内容。QuerySets支持 链接，以便您可以在多个步骤中构建最终查询，并且 可以对多个子搜索重复使用基本查询集。查询集 返回一个迭代器，当QuerySet完全 第一次迭代。

下面是一些使用api的示例：

fromexchangelibimportCredentials,Accountcredentials=Credentials('john@example.com','topsecret')account=Account('john@example.com',credentials=credentials,autodiscover=True)foriteminaccount.inbox.all().order_by('-datetime_received')[:100]:print(item.subject,item.sender,item.datetime_received)

分页

寻呼EWS服务（例如finditem和）的默认页面大小为100。你可以 如果需要，请全局更改此值：

fromexchangelibimportCredentials,Accountcredentials=Credentials('john@example.com','topsecret')account=Account('john@example.com',credentials=credentials,autodiscover=True)foriteminaccount.inbox.all().order_by('-datetime_received')[:100]:print(item.subject,item.sender,item.datetime_received)

如果您使用的是非常小或非常大的项目，这可能不合理 价值。例如，如果要检索和保存带有大型附件的电子邮件， 您可以根据每个查询集更改此值：

fromexchangelibimportCredentials,Accountcredentials=Credentials('john@example.com','topsecret')account=Account('john@example.com',credentials=credentials,autodiscover=True)foriteminaccount.inbox.all().order_by('-datetime_received')[:100]:print(item.subject,item.sender,item.datetime_received)

最后，在account类中定义的bulk方法有一个可选的块大小 参数，可用于在获取、创建、更新时设置非默认页大小。 或删除项目。

fromexchangelibimportCredentials,Accountcredentials=Credentials('john@example.com','topsecret')account=Account('john@example.com',credentials=credentials,autodiscover=True)foriteminaccount.inbox.all().order_by('-datetime_received')[:100]:print(item.subject,item.sender,item.datetime_received)

会议

日历项类允许您发送会议请求 您发起或取消以前已开始的会议。它 也可以处理接收到的会议请求消息。 您可以使用acceptitem回复这些消息， tentivelyacceptitem和declineitem类。如果你收到 取消您的会议（classmeeting cancellation） 已经接受，然后您也可以通过删除条目来处理这些 从日历中。
