We are in process with a staged migration to Exchange Online. Currently have 3 on premise mailboxes migrated to Exchange Online Plan 1. Before going much deeper into the migration I need to understand administration of FOPE.
Postini is our current provider for email filtering. For one of the migrated users i have turned off spam and virus filtering in postini in order to see how FOPE process the inbound messages. I see no quarantine of messages in the FOPE administration center. Nothing for any users for at least a month. I have also created a policy to quarantine inbound messages with "inboundpolicy" in the subject line for all users and all domains. Sending messages from an external email account with the exact matching subject line does not quaratine the message.
So what am I missing here? It seems like basic email filtering but i get no results. Please help.
