A Python package to interact with Exchange Web Services

py-ews is a cross platform python package to interact with both Exchange 2010 to 2019 on-premises and Exchange Online (Office 365). This package will wrap all Exchange Web Service endpoints, but currently is focused on providing eDiscovery endpoints.

py-ews has the following notable features in it's current release:

  • Autodiscover support
  • Delegation support
  • Impersonation support
  • Retrieve all mailboxes that can be searched based on credentials provided
  • Search a list of (or single) mailboxes in your Exchange environment using all supported search attributes
  • Delete email items from mailboxes in your Exchange environment
  • Retrieve mailbox inbox rules for a specific account

Currently this package supports the following ServiceEndpoints:

  • Autodiscover
  • DeleteItem
  • GetInboxRules
  • GetSearchableMailboxes
  • ResolveNames
  • SearchMailboxes


OS X & Linux:

pip install py-ews


pip install py-ews

Usage example

The first step in using py-ews is that you need to create a UserConfiguration object. Think of this as all the connection information for Exchange Web Services. An example of creating a UserConfiguration object using Office 365 Autodiscover is:

from pyews import UserConfiguration

userconfig = UserConfiguration(

If you would like to use an alternative Autodiscover endpoint (or any alternative endpoint) then please provide one using the endpoint named parameter:

from pyews import UserConfiguration

userconfig = UserConfiguration(

For more information about creating a UserConfiguration object, please see the full documentation on our ReadTheDocs page.

Now that you have a UserConfiguration object, we can now use a ServiceEndpoint. This example will demonstrate how you can identify which mailboxes you have access to by using the GetSearchableMailboxes EWS endpoint.

Once you have identified a list of mailbox reference ids, then you can begin searching all of those mailboxes by using the SearchMailboxes EWS endpoint.

The returned results will then be deleted (moved to Deleted Items folder) from Exchange using the DeleteItem EWS endpoint.

from pyews import UserConfiguration

userconfig = UserConfiguration(

# get searchable mailboxes based on your accounts permissions
referenceid_list = []
for mailbox in GetSearchableMailboxes(userconfig).response:

# let's search all the referenceid_list items
messages_found = []
for search in SearchMailboxes('subject:account', userconfig, referenceid_list).response:
      # we can print the results first if we want

# if we wanted to now delete a specific message then we would call the DeleteItem 
# class like this but we can also pass in the entire messages_found list
deleted_message_response = DeleteItem(messages_found[2], userconfig).response


The following is an example of the output returned when calling the above code:

Development setup

I have provided a Dockerfile with all the dependencies and it is currently calling bin\ If you want to test new features, I recommend that you use this Dockerfile instead of a virtualenv. You can call the following to build a new container, but keep the dependencies unless they have changed in your requirements.txt or any other changes to the Dockerfile.

docker build --force-rm -t pyews .

To run the container, use the following:

docker run pyews
