X-Originating-IP email header not included with emails accessed through davmail

Firstly, thanks for developing and maintaining such a useful program, much appreciated! However, the "X-Originating-IP:" header does exist in the messages I'm writing about. The outlook web app (https://outlook.office.com) and microsoft outlook desktop app both show the "X-Originating-IP:" header for the messages that have it, while looking at the same emails through DavMail doesn't have it. Is there anything that could be going wrong?

I'm using DavMail version 5.5.1-3299 on macos, and several email headers are missing when I access email through DavMail. The main one I'm looking for is the "X-Originating-IP:" header, but these are missing as well: X-MS-Exchange-Organization-MessageDirectionality: X-Originating-IP: Return-Path: X-MS-Exchange-Organization-ExpirationStartTime: X-MS-Exchange-Organization-ExpirationStartTimeReason: X-MS-Exchange-Organization-ExpirationInterval: X-MS-Exchange-Organization-ExpirationIntervalReason: X-LD-Processed:...
