Office365 Graph API - Mark as Read/Unread not updating lastModifiedDateTime

When emails are marked as read/unread it doesn't seem to update the lastModifiedDateTime attribute, so I'm not sure how my application can pull down this change. I had been planning to use a query with a filter on lastModifiedDateTime to check for all actions/changes to emails.

Steps to reproduce:

1) Perform this query in Graph Explorer

https://graph.microsoft.com/v1.0/me/messages?$orderby=lastModifiedDateTime desc

2) Mark an email as read or unread in Outlook OWA

3) Perform the above query again, and notice that the email you marked as read/unread has not jumped to the top of the list

Any help would be much appreciated!

Marking read/unread has historically not modified the message itself. Are you trying to track changes? If so, take a look at message sync which is in preview. It will send a change event if you mark read/unread.
