@Vasil Michev - I have a task to also look for message size for inbound and outbound for every single user. I followed https://gallery.technet.microsoft.com/office/Office-365-Mail-Traffic-afa37da1/view/Discussions#conte...
unfortunately, i can only extract 2 - 3 days worth of data. Since get-messagetrace can retrieve up to 7 days and page-size limitation etc.
How can I go beyond 30days to complete this task?
anyone has any script or tool that could help me with this?
