It looks like there is nothing that you need to enable per the blog post, so I've updated my initial post. I would recommend that you keep an eye on this log source after 1 Oct just to make sure it does not error out.
------ updated text ------
QRadar calls our log source Microsoft Office 365 Message Trace, but Microsoft calls their feature Message Tracking. Per the blog post, there is nothing for customers to enable or request from Microsoft per this text:
"Reporting Web Service Endpoint
For those of you using the Reporting Web Service REST endpoint to get access to Message Tracking Logs and more, we're also announcing today that this service will continue to have basic auth enabled until Dec 31st for all customers, no opt-out or re-enablement is required. And, we're pleased to be able to provide the long-awaited guidance for this too right here."
-----
So, you should NOT be required to make any special requests at this time as our development teams for QRadar work with Microsoft on a protocol update to resolve the basic auth issues.

We are collecting message trace logs. I forwarded the link to my tenant admin.
