Troubleshooting Retention Policies in Exchange Online

nhawk258 Thanks for the advice. I opened a ticket with support but they seem to doubt it is them and wanted me to manually move mail from the main mailbox to the archive to see if that works.... So basically they want me to be the manual MRM system? I don't think I am getting the Exchange PG support here with that suggestion. Further they told me if I move enough email from the primary box to the Archive things will just start working. That sounds like the biggest BS in the world.

This is what I get with another user of the same tenant who's mailbox is 70GB full and Online Archive is 168GB (which must mean that the Expanding Archive has already kicked in since it is greater than 100GB)
