AddDelegate support - possible to pass in a custom envelope?

[janczawadzki]

This is an awesome library - thank you! Ran into needing the AddDelegate call, which isn't supported. Is there some mechanism that would allow me to construct a custom envelope and pass it in then parse the results in my code, but leveraging the existing connection/auth etc?

The easiest is probably to just implement the service in exchangelib. You could use https://github.com/ecederstrand/exchangelib/blob/master/exchangelib/services/get_rooms.py as a template to create your add_delegate.py file. Elements needed to construct and parse the XML would be added to https://github.com/ecederstrand/exchangelib/blob/master/exchangelib/properties.py. There are plenty of examples there showing how to implement XML elements as Python classes.

If you want to go more low-level, the .get_payload() method should return an lxml.etree.Element object. You can use exchangelib.util.to_xml() to create such an element from a bytes object containing your hard-coded XML request. Parsing of the response starts in exchangelib.services.common.EWSService._get_elements() but exchangelib.services.common.EWSService._response_generator() may be the one to override if you just want the raw response from the server.
