Find who modified Exchange meeting

I have an end user who shows that a meeting on her calendar was last modified by her even though she did not modify the meeting. I've done some testing by having a teammate create a meeting on my shared calendar. The meeting showed that I last modified it. I adjusted the calendar view to show the organizer but it still states that I am the organizer.

So my question is, is there a way to identify a meeting event on your calendar and then to view the properties of that meeting object. For example, what would uniquely identify meeting X and how would I access the properties of meeting X to show the value of something like a lastmodifiedname property. The end goal would be to show when a specific meeting was modified and exactly who modified the meeting.

Right now, we are using Exchange Online (Office 365) in a hybrid configuration... this end user has been migrated to the cloud. Any ideas on commands that I could use to get the information i'm looking for?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

If you have auditing enabled on the mailbox, reviewing the audit trail should give you some idea. If you have not enabled it prior to the modification happening, it will not be of no help as it doesnt include past events.

Other than that you can look at the meeting properties via MFCMAPI or similar.
