vi /home/install/phx_iso/phoenix/sysUtil.py
Modify the SSD IOPS requirements

SSD_wrIOPS_thresh = 1000
set normal hdrive as ssd
type “fdisk -l’ and identify which disk your SSD is. In my case it was “sdb”
cat /sys/block/sdb/queue/rotational (0 means SSD, 1 means HDD)

search outlook for meeting requests
messageclass:ipm.schedule.meeting
Since both “schedule” and “meeting” are pretty unique for the message class, you can also shorten this to one of the following to get the same results:
messageclass:schedule
or
messageclass:meeting
