Base my revious discuss about O365 file rotation interval . I change it to 600 (10 mins) to fast check testing event.
then I create O365 policy....each policy set monitor All events.
Then I test common testion cenarios like mail move/delete , user delegation(send as / send on behalf) in 10 mins.
But I find these testing events ....sometimes could be receive...sometimes not receive (I have wait 1 hours).
Who has use O365 module to monitor Exchange Online ??
