Outlook logging was left on for some period of time, no issues, so Outlook logging was turned off and the issues did not reappear.
Outlook logging I believe was on for a few days.
Further questions. What the OS of these device? Windows 10? Prior to this conclusion that turning on/off for Outlook Logging, did you actually check the Reliability Monitor (Control Panel\System and Security\Security and Maintenance) for the Outlook or EventViewer to see Outlook crash happened again?
Just a bit odd that by turning on/off for Outlook Logging solve the issue. Excellent observation though.
Waiting for the feedback.
