I used below procedure to export emails from Office 365 Exchange Online Archive and import them into Mac OS X Apple Mail while doing PST to MBOX format conversion.

If Mac is failing to go to sleep or is waking up unexpectedly, you can run pmset -g log | egrep '\b(Sleep|Wake|Start)\s{2,}' in terminal to inspect last sleep/wake events

$pmset -g log | egrep '\b(Sleep|Wake|Start)\s{2,}'$
